Horrible!
Don't waste your money. This app does not detect anything but shaking or movement of your arm. It had my heartrate between 40 and 200+ bpm. If I took my own pulse, it was 65-75 bpm. Please don't buy this. I wish there was a way to get a refund!
Doesn't work. Based on shaking

Easy way to figure out your heart rate after exercising.
Works!
Cool app
