Kardia works with the FDA-cleared KardiaMobile or KardiaBand ECG devices— the most clinically-validated mobile EKG solution on the market.

Just touch the sensors on your Kardia EKG device for 30 seconds to capture a medical-grade EKG anytime, anywhere - no probes or wires necessary. Get an immediate result from Kardia's Instant Analysis of Normal, Possible AF, Bradycardia, Tachycardia or Unclassified. Additionally you can choose to send the recording to your physician or to one of our partners for a paid Clinician Review. (Clinician review available in U.S., U.K., Ireland, and Australia only).

SmartRhythm workout monitoring is a system that takes your heart rate and activity data gathered from the Apple Watch during workouts, and evaluates it using a deep neural network to predict your heart rate pattern. If your heart rate differs from the neural network prediction, SmartRhythm will notify you to record an EKG with your KardiaMobile or KardiaBand. Kardia integrates with Apple Health to monitor users heart rate during workout.

New U.S. accounts will have their first EKG sent to our partners for review by a U.S. board-certified cardiologist free of charge (a $19 value within the app). You will be blocked for up to 24 hours from EKG features until the review is complete. This will only happen with your first EKG, all future EKGs on your account will give you a Kardia Instant Analysis, and allow you to review your EKG immediately.

The Kardia app, paired with Kardia Mobile, is recommended by leading cardiologists and used by people around the world for accurate electrocardiogram (ECG or EKG) recordings.Record your heart health data with the medical accuracy your doctor can trust.

NOTE: Requires KardiaMobile or KardiaBand hardware to record an ECG

This wonderful Device for people who have heart you can you can write my self now I did my own EDG

This device is wonderful expressionally how little it cost £99 I suffer with a condition called Hypertropic cardiomyopathy, I have an ICD implanted in my chest, but now I’ve got this device, and when I get chest pains I will know how serious it is and it calls me not to call an ambulance which could be saving someone else’s life, I have an iPhone and an Apple Watch 3, my heart beats what Apple go great to your device plus I’ve got her blood pressure machine which does go to my device quite expensive and also I have giving me readings if I’m hot or cold or have a temperature which goes directly to my device then I got this temperature that goes directly to my app and most important of all I now own a kardia and got a fantastic app, and believe you me it is very accurate as I had been in hospital and because my ICD is pacing my heart as well you can see The difference because when my I tested it on my wife counterfactually a different reading amazing so I would highly recommend it the app is absolutely beautiful and that’s all I can say about this wonderful app & device, highly recommended, 100%

Kardia has been a reassuring tool to have, my doctor, David Jackson in Jersey Channel Isles Britain first suggested it two years ago after I thought J might have overheard some nurses mentioning atrial fibrillation and I thought they were referring to me and had not liked to question them!
Through using Kardia and being told every time that my heart was normal this did a lot to allay my anxiety which was raising my blood pressure adding to other stresses I was feeling.
Now in the last week I Dr Jackson has allowed me to stop taking Atenolol beta blockers after 14 years and has put me on a diuretic instead, this after recording my blood pressure 4 times a day for many months and I can see on Kardia that my resting heart rate has increased from about 67 most days to about 87 and a bit higher which really needs to come down. Chronic fatigue and arthritis are factors so any advice would be useful, thank all very much for your work in producing and maintaining Kardia .

Generally works well

The app generally works well although it occasionally stops responding once an EKG has been taken, requiring a restart of the app / phone. The Apple Watch app is probably as good as apple let it be but has issues. Most problematic is the battery usage - it rapidly drains the watches battery. Also, having to have the App as my watch face is not really good enough. I don’t want to have it in the foreground all the time.
As an aside, charging for a cloud platform when the hardware (Kardia mobile device) has already been paid for is not really on. Only a lack of competition enables this practice to happen and once the trial period is up, I for one won’t pay for the convenience of having a history of my ekgs stored on the cloud (especially when they could be stored locally anyway!).
