What's My Heart Rate allows you to measure your heart rate by just looking at your screen. It's easy and convenient, without the need to press your finger on your camera lens. Your heartbeat causes micro color changes on your face. What's My Heart Rate uses the front camera and a software algorithm to detect these micro changes, with beat-to-beat accuracy. The algorithm is based on the non-contact photoplethysmography concept.
