About Qaly | ECG Reader
Irregular heartbeat? Inconclusive ECG?
On Qaly, get your ECG read by certified experts within minutes. 500,000+ ECGs read so far!
All ECGs on Qaly (formerly ReadMyECG) are analyzed by certified cardiographic technicians - trained to read ECGs for palpitations and abnormal heart rhythms like Afib, SVT, PVC, PAC, PR Interval, QT Interval, and more.
Join 200K+ heart heroes signed up with Qaly (formerly ReadMyECG) — the only app where human experts analyze ECGs from your Samsung Watch, Fitbit Watch, Withings Watch, KardiaMobile, WHOOP, Garmin Watch, or any other device within minutes, day or night.
Qaly is built by Stanford engineers and physicians, including Dr. Marco Perez, Stanford Associate Professor of Medicine and Stanford Clinical Cardiac Electrophysiologist.

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 smartwatch 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

Qualy *was* a great 3rd party app for me since I have a Samsung watch and pixel phone. But now, it appears Samsung is no longer supported. F- on that decision.
