📝 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.

Kardia integrates with Apple Health to create a combined view of your health metrics.

Great system it showed I had again and I sent it to my cardiologist and they confirmed the diagnosis and performed an ablation. All is fine with me now…

★☆☆☆☆ Really bad move
How dare you pull the Kardia app out of the Omron app without warning, thus losing all of my EKG history in the process? I had a meeting yesterday with my electrophysiologist, and essential information I needed to share with him was gone. …
★☆☆☆☆ BLOATWARE
Seriously, pare it down. Just do it.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
