As a medical pro I can't get this to work with any accuracy at all. It just doesn't work I'm afraid. Use your pulse at the wrist and a watch if you're really interested. If you are worried about your heart rate see a doctor.
Garbage app. When run on my huawei watch notification tells me there is no heart rate sensor. All other heart rate sensor apps stop functioning. When uninstalled, other heart rate sensors work again. Terrible sloppy programming.
Huawei watch gets error "no heart rate sensor on this watch. Inoperational." But there is actually a HR sensor. Tapping on lets you actually into the app and it then seems to work. Needs fine tuning to remove that error message. Edit: now not working at all.
On my G4, this app works incredibly well: keeps a graph of the beats for any duration, all available in the history. Best of all, it clearly picks up and displays irregular beats, so you can see, clearly, what you're pulse is doing. I have an ectopic beat, and this app is really useful to keep tabs on it. I've only used the inbuilt flash - but it works flawlessly. The only thing I can't get to work is the exporting of data in PDF. Highly recommended: the best of its kind that I've tried.
Need manual on what certain things mean like little heart and circle. Cool if it picked up arrhythmia. On tablet it crashes quite often. Haven't got it to work yet.
Never use it if you don't want to kill your battery. It is functional that's true the app is very good but it almost kills battery permanently.
