About this app

Kardia works with the FDA-cleared KardiaMobile, KardiaMobile 6L, or KardiaBand personal EKG devices, which can detect the most common arrhythmias in just 30 seconds. The Kardia app is designed to make managing heart care from home easier than ever, giving you the ability to seamlessly record EKGs, share heart data with your doctor remotely, keep track of your health history, and more.

Capture a medical-grade EKG with your Kardia device anytime, anywhere—no patches, wires, or gels required. Get an immediate result from Kardia's Instant Analysis of normal, possible atrial fibrillation, bradycardia, or tachycardia. For additional analysis, you can choose to send the recording to your physician or to one of our partners for a Clinician Review by a cardiologist (US, Australia only) or cardiac care physiologist (UK, Ireland only).

The Kardia system is recommended by leading cardiologists and used by people around the world for accurate EKG recordings. Track your heart health data from home with the medical accuracy your doctor can trust.


NOTE: This app requires KardiaMobile, KardiaMobile 6L, or KardiaBand hardware to record an EKG. Get your Kardia device now at alivecor.com.

The new display following an EKG is poorly laid out. The old display clearly showed the results at the top and was easy to view. I had to look around for my results this time. Not a good change when you're having an episode. Also, there's a typo in the "Unclassified" paragraph outlining the different results one might get with Kardia.

I have been unable to use my app for awhile now. No matter what I do it will not pick up the signal from my Kardia Mobil to read my session. I have followed all of the troubleshooting tips and checked compatibility but no luck. It only hears me moving the device on the table. Super frustrating to have something become useless. I have switched out the battery even and no luck.

We are sorry for the frustration. Since you have already replaced the battery and checked your phone's compatibility, the issue could be related to your phone's microphone settings or a hardware defect. Please reach out to us directly at support@alivecor.com so our technical team can investigate this for you.

My app got updated this morning (as well as 26 others, and some of them again this evening???) and now it doesn't work. I've restarted my phone twice, logged out & back into the app. It shows full battery and good connection, but nothing else happens. The EKG does not show/not recording. 6L device, was working fine last night. If I switch to the single lead EKG, that works. The 6-LEAD is non-functioning.
