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

It provides a good service with a fair price (all things considered). However, this app tends to get real buggy at times and crashes a lot. It appears to me they need to update it in such a way that subscribers don't lose their data afterward, and the app doesn't keep crashing. They accomplish that, and it's a 4-star app at the least. NOTE: I own a Samsung 21 Ultra, so my phone isn't too too old.

Results were fast. Technician was very helpful and friendly. I was expecting something automated and got someone who seemed to care and personalized my interpretations with how I was feeling. I think this is a great app that can truly help a lot of people. I hope more will be offered on it soon. Unfortunately, it is a bit pricey and I am unsure of how often people will use it who subscribe.

Great app, gives access to EKG function on non-Samsung devices. Unfortunately it doesn't support orientation changes, so the only way to get an accurate reading on your right arm is to wear the watch upside down. It should adjust the scan based on the device orientation settings, since the built-in EKG mode does this. If it did that, it would be a 5-star app. But because I have to take it off and wear it upside down on my other arm to perform a scan that isn't inverted, it's useless.
