Inconsistent on signal
Greenscales2
Often it takes many attempts to get a good read / even when I know I haven’t moved it drops a good read at the end. Amplify this when I am trying to take a measurement after a workout. Often that read is off because it takes too much time.
Extremely Inaccurate Optical Heart Rate Measurement Algorithm

Measured 78 BPM when actual HR was 84 BPM. Developer to overhaul & code a new detection engine for Cardio’s red pulsations optical sensing algorithm
Works well - annoying setup

I dropped a full star for the annoying 15 step setup most of which was to please some lawyer in their back office. The app works pretty good on iPhone. Don’t bother on iPad unless you only use it in great lighting.
Very helpful and accurate.

I've been using this app a lot lately. I just had heart surgery, and compared it to the hospital ICU instruments and it was dead on. Now I pay more attention to my heart rate, especially if I feel funny at all. Totally recommend this. I use this A number of times during the week. A few times I had some funny feelings in my heart and it kind of confirmed it and so therefore I was more conscious of what was going on
Wonderful‼️

I love this app it gives me accurate results and lets me see when my heart is going wonky. My only complaint is that it won’t record when my I’m having problems because it believes it’s a weak signal.
