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, 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

Terrible and dishonest customer support. Wrongly blames GDPR for their poor UI choices.


The app recently requires that you put a password on your pdf export of your data, before emailing it to yourself or your doctor.

The ECG data is my own. I want to email it to myself, but before I’m allowed to it is annoyingly forcing me to assign a password. This impacts my medical viewing software from reading it, I have to them remove the password on a PC.

I sent a letter to customer support asking they make this optional.

The first reply told me there was a “skip” option. I replied back with a screenshot showing there was none.

I was then told this was an intentional feature and the “new GDPR security requirements have made this mandatory for us to do so”

I am very familiar with the GDPR and that explanation is pure nonsense. The data is on my phone and is my data. I am not lawfully required to password protect my own data. Data housed on their servers must already be encrypted and secure, to prevent breach, but none of that had anything to do with me putting a password on a PDF that I am emailing from my mobile.

It’s purely obnoxious and an abuse, in my view, for customer service to simply use the GDPR as an excuse for not making a potential annoyance optional. If they didn’t want to make the adjustment, so be it, but to blame the law is dishonest.

That level of dishonesty/ignorance is concerning, as it raises the question is there anything else?

Does the trick


It works great. It's probably a limitation of the hardware that you can't really record a measurement while on the move. Not a criticism but it would be great. Only thing I would change about the app is the launch/home screen. It should really just be a large 'Record your ECG' button with a duration option (30sec, 1,2min etc). It's lost in a whole list of other things e.g. Apple Watch, Medicine reminder etc which all could be in the top sub menu. Just makes it slightly awkward and slow to take a quick ECG which at times is really important to catch an irregularity really quickly.

Developer Response

Thank you for the feedback, i've created an improvement request to have it looked over by our product and engineering team. As to an "on-the-go" product, you may want to take a look at our recently released KardiaBand product that lets you record an EKG from an always ready Apple watch face using a new watch band EKG. It still requires you stop walking to take the recording, but it is very unobtrusive and discrete, and you never have to even open the phone app.

Please let us know if you have any other issues.

Connection established but no recording


I have had many issues with this app so have been unable to record a palpitation when it happened which defeated the purpose of me buying it in first place. I seem to have a good signal with the Kardia but the count down does not start and this is after changing batteries and restarting the app over and over again! It is an expensive piece of equipment and FDA approved. I do have high expectations.
