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.
