The Future of Heart Health
EKG being taken on a desk with Kardia Mobile and the Kardia App

If you are one of the millions of people who experience heart rhythm abnormalities, you know that having immediate access to EKG data, and the ability to share that information with your doctor is potentially life changing. For these reasons, AliveCor has pioneered the creation of mobile devices to enable proactive heart care, and transform cardiac care as we know it. Recognized around the world, KardiaMobile is the most clinically validated mobile EKG solution on the market and is recommended by leading cardiologists.

Our simple-to-use mobile device and app-based service provides both accurate and instant analysis for detecting atrial fibrillation (AF) and normal sinus rhythm in an EKG. Using advanced artificial intelligence, mobile, cloud, and microelectrode technology, AliveCor empowers users to proactively manage their heart health, and provides the potential to vastly improve the quality of care in the fight against heart disease.

Customer questions & answers


Do I need a subscription plan to use Kardia? Is there a monthly fee?


No, the subscription plan with KardiaMobile is optional. Basic service allows unlimited recordings of EKGs with instant analysis and the ability to print or email the recording to anyone right after you take it. You can also track your blood pressure if you pair the Kardia device with a compatible Omron BP monitor. The Premium membership comes with additional features like unlimited cloud storage of your EKG history, a customized monthly report mailed to you to share with your doctor, and the ability to track activity and weight. All new Kardia customers receive a free 30 day trial of Premium service. You have the option of upgrading to Premium within the app at any time ($9.99/month or $99/year, No commitment required).


Will Kardia work on my smartphone or tablet?


Kardia is compatible with many popular smartphones and tablets. Since KardiaMobile is a medical device regulated by the FDA, rigorous testing must be completed before we can claim compatibility. Compatibility information is located here. This list is updated regularly.


Does the EKG detect PVCs, PVACs, or any other arrhythmias besides "Normal" & "Possible Afib"?


No, at this time the Kardia algorithm can only classify your recording as “Normal” or “Possible AFib.” It is not cleared to communicate other rhythm types. Rhythms that could not be classified into these two categories are marked “Unclassified.” Note that all rhythms below 50 bpm and above 100 bpm even if they are normal sinus rhythm are marked unclassified. You always have the option to share your EKG with your physician to get their interpretation, or submit it for a Clinician Review directly from the Kardia app to be reviewed by a team of clinicians.


Is Kardia FDA cleared and approved by cardiologists?


Yes. KardiaMobile and the Kardia application are FDA cleared and CE marked. Federal and international bodies have reviewed and cleared it for detecting presence of atrial fibrillation and normal sinus rhythm. Many cardiologists recommend it to their patients for arrhythmia assessment, early AFib diagnosis and post-cardiac surgery monitoring.


Is KardiaMobile covered by my health insurance?


KardiaMobile is not currently covered by insurance. However, they are eligible for payment using a Flexible Spending Account (FSA), Health Savings Account (HSA) or Health Reimbursement Account (HRA).


How long does the battery last?


The internal battery in the monitor will last 1-2 years of normal use (2-3 recordings a day). Replace the dead battery with a new coin cell battery, 3.0V size ‘CR-2016’. These batteries can be found at most general-purpose stores.


Do you need to attach this device to a cell phone at all times?


No, some people prefer to keep it attached to the phone using the phone attachment clip (included). Others just carry it in their bag/pocket. Your KardiaMobile just needs to be within 6 inches of your phone/tablet when you are taking a recording (no Bluetooth pairing required!).


Information about your first EKG


Due to regulatory necessity, AliveCor needs to perform a review of the first EKG for all new U.S. accounts through AliveCor contracted U.S. board-certified cardiologist service (free of charge). You will be blocked for up to 24 hours from EKG features until the review is complete (although it is often much faster).The entire process happens with-in the app without any extra action on your part. This will only happen with your first EKG, all future EKGs on your account will give you instant analysis, and allow you to review your EKG immediately.


I have a pacemaker or ICD. Can I still use KardiaMobile?


Our devices have not been tested for and are not intended for use with pacemakers and ICD’s.

For people with cardiac arrhythmia, this is extremely valuable. It can confirm, or exclude, a rhythm problem as a cause of symptoms. It is easy to download a strip and send to your physician. It has allowed me to document infrequent rhythm problems, and then change medical management (and keep me out of the ER!).

Highly recommend!

February 23, 2018

I found out I had A-Fib just weeks before surgery. I had to have a cardio-version and luckily my heart went back into rhythm. Every time I felt a little “out of sorts” with my heart it made me nervous, so the nurse at my cardiologist gave me the info on KardiaMobile and I ordered it. It gives me comfort in knowing that things are well and I don’t have to make an appointment so often. Time and possible life saver!

March 2, 2018

Had a heart transplant just over one year ago. I check my EKG with the AliveCor every morning and have checked the AliveCor for accuracy against several hospital EKG’s. The heart rate on the AlivorCor has always matched the hospital EKG +/- 1 BPM. After seeing my AliveCor, my wife bought one too.

Awesome and Effective

February 13, 2018

The KardiaMobile has been my BEST FRIEND ever since I obtained it. I have persistent aFIB and until recently was a-symptomatic. I mentioned that I had seen something about the KardioMobile to my Cardiologist and he said he had seen a demonstration and would support me trying one out. SO, I bought one last February. I try to use mine daily as it tells me if I go back into aFIB. When I go into aFIB, I require cardioaversion to come out of it. I used to have to schedule an appointment to verify I was in aFIB, then schedule a date to be cardioaverted. Now, all I do is send a report from my KardiaMobile to my cardiologist; they schedule me for cardioaversion and just before taking me to the procedure room, they run an EKG to verify what my KardioMobile has told them - take me in and cardioaverted me. This has lessened the workload on my cardiologist and greatly enhanced my free time instead of waiting for appointments; sitting waiting to be called, etc. It is my on little Godsend piece of technology.

It's a source of comfort for me

March 5, 2018

I can use it to check not only my heart rate but also rhythm whenever I want to - especially when I feel like I might be in afib again. It’s comforting to know it’s there all the time. It works great. I’ve had mine for a couple years now and have only had to change the batteries once, which was very easy to do. I have absolutely no complaints.

I was so excited when my Electro Cardiologist recommended Kardia as a way to monitor

March 1, 2018

I was so excited when my Electro Cardiologist recommended Kardia as a way to monitor, and to educate myself, on the different types of irregular heartbeats that might be my problem instead of AFib. And, it did a great job at that. However, I had to spend a fortune in additional “analysis” by Kardia to learn what a not normal reading actually meant. And, even when it came back as AFib, I would then have to send it to my Electro Cardiologist, who would say “NOT AFib.” And, it turns out that all of the “not normal” readings were perfectly fine, without risk to me. And, lastly, the poor quality of trying to get an EKG from a cell phone power source is just going to fall short. The “static” caused really scary looking readings, which turned out to be just that … poor quality of using the power source from a cell phone with two points of contact, versus a higher quality reading you might have with a real EKG machine at the doctor’s office or the hospital. BUT, given all of those constraints (outlined above) which cost me a great deal in “extra analysis” by Kardia before I figured out what was a concern, and what wasn’t, it still beats rushing to ER for an EKG. I now know to ignore a great deal of the “artifact” (static like readings caused by the poor power source of a cell phone, even a new iPhone), and to learn what I could from this tool … the difference between a life-threatening AFib run like what killed my grandfather, father, aunt, and permanently damaged by brother, and the vast range of irregular heartbeats that are quite normal as we age. So, I now infrequently use the Kardia Mobile, and only use it if I have an irregular heart beat for a period of time. And, even when it gives me the impression I should keep paying for extra Kardia-provided analysis, I’ve learned that I can skip that stage, and just go to my Electro Cardiologist if I am concerned. It turns out that my Electro Cardiologist was right all along, that I don’t have an AFib problem. And, I suppose it was worth all that I spent at Kardia to learn what he thought all along.

The shape of tech to come.

March 1, 2018

My cardio guy told me about this device when during a routine checkup I asked him if there was any way of doing monitoring at home to see if there are any patterns to irregular heart patterns occurring. I’ve been using this for about 2 years now and coupled with a blood pressure cuff, can give some really solid day to day results you can use for better heart health.

Won’t let you see your first strip or measure again until a cardiologist reads it!

February 27, 2018

So, I’m a physician and ordered the Kardia device. When you create an account, it doesn’t show you your first measurement and it prevents you from measuring your rhythm until your first one is read by a cardiologist. So I own it but can’t use it until it’s read by cardiologist. There are cheaper devices available that don’t put this restriction. I read my own ecg in my practice daily but apparently am not qualified to read this one. I have an ekg machine in my office but can’t read the kardia rhythm.

Very helpful

February 22, 2018

I am an early adopter of the Alivecor technology (long before it was on Amazon). It was recommended by my cardiologist, I think I served as part of their data collection and testing, and the device proved very helpful to me. How is it helpful? It provides some objective evaluation of my heart function and some subjective peace of mind that I can test what I cannot see or feel. This technology has allowed me to send PDFs of my EKG to him for review if I am puzzled by the results. (Complaints? When it was in the testing phase, the user interface was functionally simple. Having gone commercial, the user interface is colorful and cluttered. I preferred functional simplicity.)

Highly recommended for afib sufferers, easy to use

February 21, 2018

I have had afib since 2013 and found Alivecor since 2014. Love this portable ecg reader, i can measure my ekg daily and or weekly and save them to my samsung phone and the cloud. The process take 30 sec, painless, just hold alivecor device with both hands for 30 secs. My cardiologist gave the nod of approval to this device. After 3 ablations, i am afib free for over 15 months now. It is so nice to be able to check m. y own ekg at home on a weekly basis forthe one time price for 150 $ and now $99. So far, i only had to change the battery 1 time with a readily available battery from a local Walgreens or Home Depot.

A must for an A-Fibber

February 20, 2018

What a piece of technology! And the price is reasonable. I have A-Fib, and with the touch pad, I can check my ECG any time. If I feel a flutter, or anything out of the ordinary, I can check it. I send a copy to my cardiologist once a week unless something stands out and I feel it needs attention. My cardiologist loves it. I had a failed conversion, and now I am waiting on additional treatment. By sending in my weekly sample, I have avoided additional trips for office EKGs. Since I am in flux as to treatment/outcome, I decided to enrolled in the Premier plan for the year. It gives me more detail, history, and a monthly summary. Which is important at this time. The Heart Education in the app is very informative and easily understood. I wonder if at some time there might be a place that I can enter my oximeter readings. I am surprised at how many ‘heart people’ don’t know about this thing. I am showing everybody and everyone love’s it! Now if we only had something like this for Diabetes. Got A-Fib….get one!

Incredible technology.... my Doctor recommended the unit

February 18, 2018

It gives me immediate feedback. After a walk, workout or any activity I can see immediate feedback of a irregular rythum and can recheck often to see when it stops. Only thing I have an issue with is if you don’t purchase the $99 Premium service you can’t recall your history or get a monthly report.

Probably worth the cost ...

February 15, 2018

Upgrading from 1 to 3 stars(see below). Being able to at least get some kind of a read on my EKG is worth $99. I just hope they seriously reconsider how the app works and looks.

I showed it to my PCP. She thought it was useful but had nothing to compare it to for me at the time of course. Next time I get a strip run we’ll see I guess.

Oh, I finally noticed a link to the user guide here on Amazon. I suggest you read that before you buy. To be fair to Alivecor, I may have missed that. If they just added it, kudos for listening. I still think that needs to be more obvious given what this is.

Prior Review: Virtually nothing is said about the first reading needing to go off to a board certified cardiologist and that I would have to wait up to 24 hours before I could see my first result until you actually go to use the device. If my readings don’t work with the device am I out $99. Unbelievably frustrating. I really am beginning to feel like this is being operated as s hook to pull people into paying for a bunch of “services” that they don’t want.

Potential life saver

February 14, 2018

My chronic atrial fibrillation was treated by cardiac ablation after two failed conversion attempts. Now I check my EKG every day and can rest assured when Kardia reports no abnormalities noted. Any questionable readings get sent to my cardiologist (who uses one himself) for follow up. I keep it attached to my iPhone and can also easily check if I am feeling any adverse symptoms during my daily activities.

Necessity for Afib Patients.

Necessity for Someone with afib. I am not without the device. I have it with the phone case. This tells me whether I am in afib. Only three diagnoses allowed by FDA so I did learn a bit about reading ECG with my doctor’s help. The response time is quick. I can also emailed the readings to a doctor and have printed them myself. If I am not feeling quite right I will take a reading just to restore confidence that I am not in afib. Recommend to anyone with afib.

Provides peace of mind

February 9, 2018

As I heart failure patient I often feel palpitations and strange rhythms in my heart rate. Have been using KardiaMobile for couple of years (back when it was AliveCor) and am trilled with what it provides. I can now see and identify the strange sensations within my heart rate (Premature Ventricular Contractions show very well as do other arrhythmias). By reading and discussing with my Cardiologist I can now identify many of these arrhythmias via KardiaMobile. I have an implanted cardio version defibrillator (ICD), and as long as it is not pacing I get good readings. Very convenient to use as it is attached to my phone and always available. I take summaries to my doctor appointments. Provides real peace of mind. Have recommended to a number of folks.

A must have medical device for those with AFIB

January 16, 2018

I absolutely love this Kardia. I use it all the time to confirm whether or not I’m in AFIB. I also use secondary devices to confirm what Kardia is telling me, but Kardia will do the trick on its own. They offer an upgraded plan where one can have a “Clinician” read your results, I partook of this, but I found the Clinician’s review was nothing more than what Kardia had already said, so in my opinion a waste of time and money. I do like it though that you can get your results on their Server for an extended period of time. The Kardia can now be paired with the Apple Watch, I got one, but I haven’t set it up yet and when I do, I will report back. BTW, I came across an ER Doctor who keeps one attached to his iPhone, when a patient comes in who has questionable or no insurance, he can use the Kardia for a quick mini EKG without cost to the patient or the hospital to triage out the patient.

It will cost you 99 for the device and 10 a month if you want to use it. I can’t recommend it for anyone.

January 14, 2018

I bought this for my husband. Nice device for 30 days. You pay 99 for the device and after 30 days you have to pay 10 a month to be able to save the EKG reading. This should be spelled out in bold and plain language before the product is ordered. It is useless to me now as he has no readings to review with his physician.

Only as good as the doctor reading the reports!

January 11, 2018

This is such a good idea. While I am not sure of the accuracy, as someone with heart issues, it is comforting to have. You can stick it to the back of your phone and always have the ability to monitor your heart. Now, the one drawback comes when you consider what you are doing with the data. I was looking at it myself and gathering ZERO helpful information (as you might expect, I am not a doctor). You can set this up to send the report to your doctor, but this requires your doctor having any desire to receive EKGs from you anytime, 247. And, if by some miracle, he elects to receive the reports, do you think he is actually reading them?? If you do then you found a good doc and you should hold on to him. I showed my doctor the device when I bought it, and when I came back after a month and talked about the device with him, he was amazed (as if we did not discuss the device in detail a few weeks prior). So, it was apparent he was not looking at the reports…

Nice to have to check for afib

January 8, 2018

Sure a nice product to have. It is quite compact and small. You need to download an app to your iphone first. Open the app, place your fingers on the two pads and wait about 30 secs. while it records your heart beat/rate. When you are finished you receive a response as to whether you have an identifiable problem or not. What is nice is that you can email it to yourself or someone else. Then you can print it out and take it to your physician if you wish. You can pay for a premium service that keeps records for you if you want to do so. Very good if you are watching afib.

Afib detection fantastic

January 2, 2018

I have written very few reviews for products, but I believe strongly that Kardia is an excellent tool for people with Afib. I have been using Kardia for a year and it is essential to my heart health. I can only speak to using Kardia with my Afib. For most of the year, I was in AFib and refused to get cardioconverted — Kardia confirmed my Afib consistently and even with my 82 year old mother. Then, once I was converted I saw through Kardia how my heart rhythm would change. My doctor did not think I would stay in sinus rhythm after my conversion because my heart had been out of rhythm for so long. He said I had a 40%chance that the conversion would work and keep me in rhythm. He said that over time, sinus rhythm begets sinus rhythm, and Afib begets Afib— so chances my heart would continue to beat properly we’re slim. I believe that by using kardia consistently, I have figured out several of my Afib triggers and I have avoided cardio conversion every time, as well as avoiding having an ablation. I alwAys have the Kardia unit with me and check my heart rhythm twice a day. And, if I feel “off” I check it immediately. I have learned several of my Afib triggers — such as not using my C-pap machine, what stressful situations precipitate Afib, excess sugar, too much alcohol - and specifically what alcohol, too much red meat, being dehydrated, and over eating. I also learned that drinking lots of camomile tea has seemed to help me self-convert back in rhythm. Over the past six months since my heart was converted, I have been in Afib for no more than 48 hours at a time — six or seven times. I believe that by knowing when my heart rhythm is off, I can be proactive with camomile tea and de stressing which together have gotten me back in sinus rhythm. Once, when I almost exceeded the 48 hour limit in Afib my doctor had put on me for a conversion, i sent his office an email of the Kardia reading. They were amazed at the accuracy and found it very helpful. I think it also helps when Readings are taken properly according to the directions.

This is a great for capturing cardiac events at home and on-the-go.

December 28, 2017

I like this device. I’m a heart patient and it’s great to be able to capture events when I’m on the go. Even though it’s not a 12-lead EKG, it’s sufficient to prove to my doctor that something went down. For example, for the past few weeks, I’ve been having a ton of PVCs, and the last few days I’ve had none that I noticed. So I have all of that data recorded in EKGs that I’ve sent over to my doc.

The iPhone app needs some work in the user experience area. Pressing the “back” button sometimes doesn’t take you back 1 screen, but back to the App’s main screen, which is annoying.

I’m still in the free trial for premium, but I don’t plan to continue the premium membership. I have a Google Apps Script set up so that I when I e-mail the EKG to myself (gmail), the attachment will get stored in a Google Drive folder with my other EKGs.

The price of the device is a little off-putting, but there is nothing else like it (until QardioCore is released, which is more expensive). But it does have FDA approval, so there’s that.

Great health tool for Afib sufferers

December 16, 2017

This is an amazing health tool. It produces an accurate and usable ekg. My cardiologist had suggested the Kardia but was not really familiar with it. After I got it I emailed the first 3 days ekg to him and he was most impressed. The one thing that bothers me most is that any heart rate over 100 is unclassified. As an AFib patient who had an ablation done but still has some rapid irrregular heart rhythms this just seems a downer.

Kept me from having to go to ER

December 6, 2017

I love that I can keep a check on my A-fib and so does my family. Has saved me from having to go to the emergency room and love that I can print a report for a specific time period and take to my doctor or email to them. I don’t recognize when my heart rate gets out of control until I realize how exhausted I am and by then it is more than double what it should be. LOVE IT!

my cardiologist suggested it

December 5, 2017

got this because my cardiologist suggested it. It’s very sensitive & I have to be in a very quite place to use it. Even then, I have to move it carefully to align with the phone mic in order to get a reading. But eventually I do. I save the reading to drive and then show them to my cardiologist at visits. He gives me great feedback from it. So it use very useful; just a little finicky.

An essential and comforting assist for those with AFib

November 16, 2017

This device is a wonderful assist if you have AFib! I have several tips which will improve the accuracy of your readings: (1) remember to sit quietly for a bit before you take a reading; (2) when start your reading, gently place your fingers on the metal pads (I actually put one hand on the pad and push “record” with the other hand); and (3) the length of the reading is adjustable in the settings and it can be helpful to change the default timing to 1 minute, upward from the pre-set 30 seconds.

This advice is very similar to creating a condition similar to the way a patient should be treated when taking a blood pressure reading – rest for a few minutes and breathe evenly, so that your heart settles down to a normal rhythm. Further, because the measure is taken by metal pads, instead of a cuff, some gentleness should be used; if you heavily plop your fingers onto the pads while the reading is being taken, you will find there is a spike in the reading which is an artifact of the pressure, not of your heart. Setting the timing to a bit longer gives a lessens the proportion of time during which that initial pressure may impact your reading.

The device will basically tell you your average heart beats per minute, as well as give a graph of your heart beats (similar to an EKG). You will also be advised if the pattern is normal, possible arterial fibrillation, or can’t be classified (the latter does come up less often if I follow the advice in my first paragraph).

While everyone’s situation is different, the use of this device allows me to have a medication which I use only when my heart rate goes above a set level of beats per minute (which, so far, has always given me a reading of possible arterial fibrillation). That is called a “pill in a pocket” approach, which I find highly desirable because my episodes are sporadic.

For anyone who has “silent” episodes – where one is unaware of a period of arterial fibrillation – this device would not only be desirable, but just about essential.

One can purchase a “premium” service for $99 per year. It is certainly worth signing up for the free trial for one month. Given your experience and condition, you may not see a need to continue the service (I didn’t but others do). And, if you do have AFib, there are some wonderful and helpful forums on the internet and Facebook.

Fantastice for a-fib and I'm not fibbing

November 15, 2017

Diagnosed like millions of others wsith a-fib. This device lets me to accurately check my heart rate any time of day. I can now check my EKG free as many times as I like and email it to myself at will. I then give printed copies of oddities to my cardiologist for review and discussion. Alivecor wants a ridicuilously priced monthly subscription to maintain records for you so I did not go for that.

Great idea, inconsistent performance

October 8, 2017

Convenient, fast health assistant. My Doctor was upset that she had not previously been told of this device/software, and had to learn of it from a patient—but she was very pleased that it was available, and initially impressed with its capability! After 90 days of use, however, I’ve found that 90% of the EKG’s are found to be either unreadable, or outside of the parameters, or receiving too much interference. This last reference seems related to how recently the phone was on charging station. So my conclusion at this point is that the device/software needs further refinement before I can trust it.

This product seemed like a great instrument to add to my cardiac healthcare

October 7, 2017

This product seemed like a great instrument to add to my cardiac healthcare. However, all the documentation I have read, both on Amazon and on the company’s website, does NOT tell you once you install the application on your phone, that a Cardiologist MUST read the first test before you can access the data. This is not what is advertised - it is advertised that this is a tool you MAY share with your cardiologist and keep track of your rhythm. I am returning it due to the misleading advertising.

Good for what it's designed to spot

August 24, 2017

For a single lead I ECG, it performs pretty well. I got it mostly to try to track what was giving me palpitations and to rule out bouts of afib or atrial flutter, and this does a good job of that. I have no problem spotting PVCs as they occur, and P wave resolution is more than sufficient to spot atrial arrhythmias (fortunately I’ve not seen any but I can clearly see that the P wave is normal). The trace presented is relatively clean. The first few seconds show a noisy trace, but then it smooths out, so the clean trace must be the result of some sort of noise reduction. There is a bit of voltage drift in the trace, so its of limited value for spotting segment elevation or depression, but it’s not designed for that. I think it does t pretty good job for what it’s designed for.

Questionable worth....

July 20, 2017

I did not read the reviews before I came here to complain. My complaints were not about the functioning of the device (or service) but I am glad I did come here before I unwrapped the thing.

First, they require me to set up an account - but they take my privacy seriously.

Second, they require me to consent to the collection, processing and disclosure of my de-identified heart activity data and related information.

Third, they require that I consent to receiving marketing communications from AliveCor.

They say that I may withdraw my consents at any time but, the web site says that if I do withdraw my consent, AliveCor “may not be able to provide to you some of the features and functionalities of the Service.”

Between these requirements and the other comments here, it does not seem to be worth the trouble. Too bad because it looked like a really cool product…

Worth the cost

June 6, 2017

It does detect AFIB. Wet your fingers before touching contacts and you will get good readings. Dry fingers cause an erratic waveform. Had one surprised Medical Professional when I showed them the results. For me the device is worth the money as you can’t always tell you are in AFIB without a means of detection.

Simple to use, an essential tool for AFib sufferers

April 24, 2017

This device was recommended by my cardiologist to use whenever I think I might be in AFib. I’ve used it a few times and I have to say it’s a very impressive piece of technology. For $99, it’s a no brainer if you have AFib or have some other need to occasionally monitor your heart beat. Overall I’m extremely satisfied with the device and still kind of amazed it’s even possible to take your own EKG using a phone.

Together with the Omron 10-series and a HR Monitor (Apple Watch in my case), you can now get a pretty amazing set of data on your cardiovascular health at home for a surprisingly small sum.

A couple of call outs:

1) Kardia charges $10 a month to keep historical records of your EKGs. I’m doing this for now, but it should be free. It’s a terrible business model. And the other things they throw in for that $10 are not valuable (i.e. tracking your BP measurements and weight when I’ve already got other apps doing that such as Omron/Withings/Apple). 2) Taking an EKG is surprisingly easy and I haven’t had an error yet. 3) I would be careful not to get obsessed with the device and start taking EKGs all the time. I’ve only used it a few times and would only think to use it if I felt a bit “off” in some way. 4) I wish the device came with a carrying case. It’s super small and wafer thin, and I’m afraid it will get damaged in some way. 5) I’m not sure why anyone would use the phone case adapter as it will permanently adhere to the case and look ridiculous. Taking a reading with the device next to the phone works just fine

PS: I am eagerly awaiting the Apple Watch band version of this product!

AliveCor Kardia Mobile saved my cousins life!!!!

April 18, 2017

Wonderful to have a tool to be able to record your heart rhythm. I used it on my cousin one night and found his rate was 144 and in A Fib. Which prompted him to get more tests and found he had blocked coronary arteries and had quadruple bypass!!! Saved his life. He was completely asymptomatic and had a pre op eye surgery stress test a few months earlier and passed with nothing noted!! Thanks Kardia, you saved at least one life!! Love this device!! It so small and compact I carry it in my small zipper of my purse just in case someone in the family is not feeling right. Its not a doctor but can alarm you to get in touch with your doctor. GREAT DEVICE!!! Thanks!

Great Breakthrough for home rhythm analysis 24 hrs a day...

April 5, 2017

I am a retired General Surgeon with a 50 year experience with intermittent Atrial Fib. The Kardia Unit performs exactly as advertised. It produces a ONE LEAD EKG Rhythm strip. A complete 12 lead EKG provides vastly more information about many more cardiac functions and diagnoses. This is ONLY going to produce a SIMPLE Rhythm which gives only a LIMITED amount of data, i.e. primarily whether you are in Normal Sinus Rhythm or not. It may for may not be diagnostic for atrial fibrillation or any other arrhythmia. Also, it, just like ALL EKGs, is very sensitive to any movement or placement of leads, etc. If the phone is placed down on a solid surface, the Kardia sensor placed directly against the bottom with the arrow pointing to the phone, index fingers moistened to improve electrical sensitivity, elbows down on table, and absolutely NO MOVEMENT of arms or fingers during the reading, you’ll get a good reading every time. A lot to get right - yes. BUT that is the nature of taking an EKG - whether it’s at your home OR in your doctor’s office. Because I’m a physician, I interpret it myself. They have very good algorhythms to try to diagnose the strip, but it’s extremely difficult to do so. A 12 lead EKG can still be difficult as well. They are going to be conservative on the analysis because of medicolegal limits. Overall, this is a real breakthrough for laymen to get a simple rhythm strip at home without going to and ER or Urgent Care center 24 hrs a day…

Great for tracking your heart rhythm. Tells you when your in AFIB and when your in NSR (normal sinus rhythm). Been in NSR for 23 days since my ablation. Best was to use the device is to hold 2 fingers on each metal pad. Rest your arms on a table and keep steady pressure on the pads. You will get a good signal and a good reading

First week judgment: really poor experience

January 18, 2017

From the start, my experience with the Kardia has been flawed. They won’t let you use it until you have an initial EKG reviewer by one of their remote physicians. After waiting 18 hours for mine to come back the result was simple that the data quality was poor and unusable. Then they let me start measuring additional EKGs, but they bagged me that since my first was unreadable I should request another initial screen. I tried to do that, but they were going to make me pay. Really? When the poor initial instructions and poor first reading resulted in no scan, you want to charge me? But I’ve learned that’s what Kardia is all about. Every time you turn around they want to upsell you with additional services for extra fees. Can’t even begin to enjoy marveling at what a cool device it is (and it is) because you get the feeling that the company is led by used car salespeople.

January 18, 2017

Have only had it for a few hours. Was allowed to take one reading, then was told that someone would need to interpret my reading before I could use it again! I purchased this to try and determine what activities made my palpitations worse and I already have a cardiologist! The fact that I can’t use it for up to another day is ridiculous. Also, as other reviews state, you only get one reading at a time unless you pay another $10/month on top of the $99 you’ve already paid. I may amend this later, but for now, it seems like they company really takes advantage of you.

Hi Alicia, We aim to make the account creation process as quick and unintrusive as possible, but as a federally regulated medical device, there are steps we must take during the account creation process. The initial lockout of up to 24 hours (but usually much faster) is one of them. In exchange for the inconvenience we provide you with a free ECG analysis by a U.S. board-certified cardiologist (a $19 value within the app). The initial lock is discussed in the app before the process begins, as well as in the Instructions for use and the user manual found at Also, please know with Basic (no monthly charge), you can take unlimited recordings, receive the instant analysis after each 30-second recording and you have the option to e-mail the recording to yourself once completed.

January 14, 2017

At first, it was a great novelty…but then the Kardia kept sending me back “Unclassified” EKG readings. Of course, not being a “Normal” reading, I ordered the review by expert several times at $19 each, and at times, the $9 review by “Technician”. And these “Unclassified” readings came back as “Normal Sinus Rhythm”!

I wrote to the company, and suggested that they either need to update their system with more EKG rhythms so NORMAL READINGS DO NOT COME BACK AS “UNCLASSIFIED”, causing concerned consumers to send the EKG off for expensive readings that come back as “Normal”.

They asked me to send them examples (a reply took three days from Customer Service). I’ve sent the samples and the reviews of the EKG strips and asked for refunds for the mis-classified EKG’s….no response yet.

So, the burden is on the consumer to “prove” their Kardia system is not reading correctly, and when their system shows “Unclassified” EKG’s that you pay for reads on, they come back as “Normal” and you’re just supposed to be happy with that?

Nope. This system needs work. A lot of work…and enough information on their servers to give a true reading of the EKG.

I am left with the feeling that the “Unclassified” readings are somehow designed (whether purposefully or by system fault) to strongly encourage the customer / patient to send the EKG off for multiple expensive “Professional reviews” (as a business model).

This system has been returned for a refund, and I suggest strongly that the company add additional functionality and stop charging for “Normal” readings by the “Professional Cardiologist” and “Technician”, respectively. $19 and $9, respectively add up quickly, and when the system is giving false “Unclassified” readings, which come back from the Cardiologist or Tech as “Normal”, then one wonders whether the system will pick-up an ABNORMAL reading if present?

I would not trust my health to this little machine nor to the “Cardiologist / Technician” readings. For a comparison, I sent the same EKG to the “Cardiologist” for $19 (“Unclassified”) and also to the “Technician” for $9. The technician picked-up an electrical disturbance in my heart…the cardiologist did not!

Finally, I had several readings of “Unclassified” which I knew were tachycardia due to my heart rate on my BP monitor and also my pulse oximeter (both exceeded 100 BPM). Both the “Cardiologist” read and the “Technician” read came back as “Tachycardia”…but that is such a relatively simple finding, based on heart rate, that it cost me $19 and $9, respectively, to find out what I already knew…but the system could not or would not show as a finding?

All in all, the product is a novelty, but it is expensive to use on a daily basis, the readings are not necessarily accurate, and the cost of reading an “Unclassified” EKG is on the expensive side.

Finally, I wonder how much time the “experts” take to read the EKG. The turn-around time on one “Technician” read was less than 20 seconds!! How can anyone receive and review a 30-second long EKG strip in 20 seconds?

I feel this company needs to update the firmware, allow more feedback to the customer / patient, and proactively review the results provided by their cardiologists and technicians, respectively, as a quality control measure.

Seams like a lot for this feature

December 22, 2016

The device seams OK for a single loop EKG. My problem is with the business model of AliveCor. Upon purchase and installing the app, seller advises that “Free trial of premium features through February 2017 including personalized heart health reports.” There is no description of basic vs premium membership, so I called AliveCor. Turns out the difference is that, with basic, you can save only ONE EKG - making historical review and trend analysis unavailable. Only Premium members will be able to store their EKG history. This removes a key feature of the device.

I asked “so, in order to save MY health data on MY phone, I need to pay for premium?” Yes. “How much” $10 per month. Seams like a lot for this feature. Disappointed this is unclear up front.



But, are you able to email yourself the results of each ekg you do? If so, you can save them in a folder in your email and pull them out when needed at the doctor or hospital, right?

Laura Hastings-Brownstein

I would just like to say that if you send it as an email, you can save those EKGs on your own computer or laptop and make the analysis yourself. It seems to me if the company saves them (I say that because the device itself is not large enough to save a bunch of EKGs), it will just be harder for you to access. Does the company provide trends or other analyses of the EKG data, or just the EKG itself?

D Feynman

To clarify, it's not my website, I have nothing to do with the product, I'm just interested in one for myself. If you are going to compare comfort, you need to compare it to the alternative. A Holter monitor requires multiple electrodes attached to your chest, and a heavy contraption to carry around with the battery and monitoring equipment. So this looks like nothiing short of a delight compared to that. I assume it goes around your chest so it can get proper readings from multiple points, but that's just a guess. It also requires enough space for a battery and so on in order to last 24 hours. So not possible with a small thing taped to someones chest.

Trying hard

It is easy to email yourself a copy of your electrocardiogram; you can store it yourself and send it wherever you like. I don't see the reason for the griping about data storage fees. I am happy with the performance over the past several months.

Really cool product that can help with your health

December 13, 2016

This thing is really cool. The electrocardiograms are decent quality (I say that as a non-medical person with absolutely no training so what I say doesn’t really count). Anyway, my doctor wants me to monitor my heart and he recommended this. He said that catching atrial fibrillation as soon as it returns makes it less damaging because it leads to prompt treatment. It’s not hard to use and it takes about 30 seconds to get a scan. That’s quick.

Works just as described!

September 3, 2016

This device works exactly as advertised. I occasionally have episodes of atrial fibrillation. I can usually tell when that is happening, but am never sure. This quickly does an EKG, and it telly you if you are in afib, The first time you use it you have to wait for their doctor to email you before you can use it again, but that is a one time thing. Once you get that first report back you can use it as often as you like. It saves the results each time so you can examine them or email them to your doctor for analysis. You can also email the results to their doctor for analysis for a fee. My only complaint is that the app won’t run on my iPad. It works fine on my iPhone 6s Plus.

I’m a physician and my father in law has been having some dizzy spells. His physician didn’t seem particularly concerned and scheduled an appointment for several weeks out, which was concerning to me. I ended up getting this device to see what his heart rate and rhythm looked like when he was having the dizzy spells. It was useful in detecting that he was in sinus bradycardia, and was on too high of a dose of beta blockers.

I love the idea but it's way too buggy to rely on, especially when you're having rythm issues.

April 11, 2016

Our doctor suggested this for my wife. She’s been having some heart beat irregularities lately and he told us we could use this device to capture EKG strips at home and send them to his office. What a great idea! We’ve been using it for a month now and unfortunately it’s far from perfect.

Pros: + We have been able to catch some weird arrhythmia’s with this device and we were able to send them to her cardiologist. + Capturing the rhythm is easy, just put your two thumbs on the metal and hold it down onto a table.

Cons: - It’s so touchy. When her heart is beating normally the EKG typically works fine but as soon as she starts having a heart problem the device sometimes gets confused and will just stop working. The EKG will cut out completely. I’m pretty sure we’ve lost some pretty important arrhythmia’s from this bug. - The phone case you can buy with this thing is practically worthless. Unless your hands are as steady as Chuck Norris, don’t expect to get anything close to an accurate reading holding the phone case and putting your thumbs on this thing. - The desktop software is crazy buggy and the website isn’t perfect either. Here are a couple bugs we’ve found. 1) You go in and make a recording, 50% of the time the recording cuts off when there is an arrhythmia. When the heart rhythm is normal the device seems to operate just fine. 2) In-order to play back the rhythm you’ve just captured on the desktop app you have to log out of the app and back in, you can’t view rhythm strips you’ve just imported. 3) In the desktop app, after viewing your rhythm if you try to view your history the app blacks out completely. Log out and back in to view your history. Then if you view another rhythm, again you can’t view your history again until you log out and log back in. Do this until you’re sick of the desktop app and you turn to the website. 4) The website works fine for some things but doesn’t work at all for others. For example, If you want to make a note to talk about what happened during an episode you cannot do this on the website. You are forced to write the notes through the phone. This limitation doesn’t make sense at all. It makes you not even want to write notes because it’s such a pain to type out exactly what was happening on your phone.

Overall I really like the concept of this device. I wanted to love it but it’s got so many problems it’s almost unusable. You need the patience of a monk to get an accurate reading that you can actually have analyzed by your doctor. The only reason this didn’t get 1 star is because we have managed to capture some interesting hearth rhythms on this device that we gave to her doctor. We will continue to use this until someone else releases a better product.
