Refuses to detect my finger – Heart Rate PRO Review

This is the only camera-based heart rate app I’ve ever tried that cannot get a reading from any of my fingers. It insists that I’m not doing it right, even when I do it the exact way the in-app help says, and the same way that other heart rate apps accept with little trouble. I’ll stick with the very old, but still completely functional, heart rate app I’ve been using for years.
