Description by Qaly, Inc. (from the App Store)
Heart feels off? Inconclusive ECG?

Get your ECGs read by certified experts within minutes, for peace of mind. 500,000+ ECGs read so far. Qaly is the leading ECG app for Apple Watch, Fitbit, Kardia, and other devices.

On the Qaly app, get your ECGs reviewed by certified cardiographic technicians, trained to read ECGs for 30+ palpitations and abnormal heart rhythms like Afib, SVT, PVC, PAC, short or prolonged PR interval, short or long QT interval, WPW, and more. Track your heart rate variability (HRV) to monitor stress and recovery.

The Qaly app (formerly ReadMyECG) is built by Stanford cardiologists and engineers, including Dr. Marco Perez, a Stanford Associate Professor of Medicine and Stanford Cardiac Electrophysiologist.

Join 200K+ heart heroes signed-up with the Qaly app today, the only app where human experts analyze and interpret ECGs from your Apple Watch, Fitbit Watch, Withings Watch, KardiaMobile, WHOOP, Garmin or any other device within minutes, day or night.

Qaly members stay heart healthy:

“I would like to thank everyone reading the ECGs on Qaly. Because of Qaly, I went to my doctor and was diagnosed with SVT and was told it was probably never an anxiety disorder. I have lived 15 years of hell thinking I was having intermittent panic attacks and agoraphobia. Getting set up for an ablation. I will be forever grateful.”

— Marcie D. from Alabama

“Qaly was so helpful in quickly identifying signs of a potentially serious heart condition … Without Qaly, I would have blown off the ECG and maybe shown it to my primary care doctor at my next appointment a few months away.”

— Lori B. from Virginia

“My Apple Watch categorizes my arrhythmia as normal or inconclusive, which makes me question what I’m feeling. Without Qaly, it would’ve taken me another 6 months to a year to take this to a doctor. With Qaly I gained valuable information. Qaly is the key.”

— Jessi I. from Washington
