Apple Icon - QALY App Store Review

Qaly gave me back some control letting me know what my weird beats were, stating if they were within a normal range and giving me some much needed information about my heart. Peace of mind obtained.

I am impressed! I received a thorough review of 3 ECGs and the technician was so helpful and friendly in their reporting. I've felt more "heard" by this app's technician than in all the time I spent with other doctors. I will be following up with my doctor, though, and I greatly appreciate this app!

With the modern availability of at-home devices that can measure ECGs, it is now challenging for cardiologists to keep up with all of these readings. On Qaly, trained ECG technicians read every ECG you submit.  If you want to learn what your ECG may be telling you, this is the place to start.

Frequently Asked Questions

Who are the experts reading ECGs on the Qaly app?

On the Qaly app, certified cardiographic technicians read your ECG.

Cardiographic technicians are health professionals — like cardiac nurses — who study how to read abnormal heart rhythms from ECGs in hospitals. These cardiographic technicians are trained to identify irregularities like SVT, AFib, PVCs, PACs, Short PR Interval, Inconclusive ECGs, and more.

Now, on the Qaly app, these same technicians read ECGs from your smartwatch or at-home ECG device, 24/7, whenever you need them to.

Most importantly, all cardiographic technicians on Qaly have successfully cleared the CCT exam administered by Cardiovascular Credentialing International, which is considered the gold-standard in heart rhythm analysis credentialing for cardiographic technicians.

I looked for an app that uses real technicians, and not an algorithm to read my ECGs. Luckily, Qaly was there at the right time for me.
