Heart feels off? Join 25K+ on QALY, the only app where human experts interpret your ECGs for arrhythmias and palpitations within minutes.

On QALY, cardiographic technicians monitor ECGs 24/7 from your Samsung watch, Fitbit watch, Kardia or any other at-home ECG device. Cardiographic technicians are experts in heart rhythm analysis who review ECGs for abnormal heart rhythms, or arrhythmias like Supraventricular Tachycardia (SVT), Atrial Fibrillation (AFib), PVC, PAC, and more.

With QALY, discover possible new cardiac arrhythmias and palpitations, track known arrhythmias and irregular heartbeats, and unlock deeper insights about your heart health through human technician monitoring.

Moreover, same-day delivery for every ECG interpretation on QALY means getting continual peace of mind before the next available doctor’s appointment.

“I would like to thank everyone reading the ECGs. Because of this app, 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, Alabama

“QALY was so helpful in quickly identifying signs of a potentially serious heart condition … Without this service 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, Virginia

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

— Jessi I, Washington
