The app measures oxygen saturation changes in your blood. On every heart beat your blood becomes more oxygen rich which causes a slight change in the color of your skin. Camera in your mobile tracks that changes and calculates your heart rate. It works similar way as a medical pulse oximeter but without a dedicated light source.

In order to measure, place your index finger gently on the camera lens. Hold it steady for at least 10 seconds. Your heart rate will be shown. Give it a couple of seconds to stabilize. Don't press too hard as this can stop the blood flow on the surface of your finger.

It is important that you use this application with good lightning. For best results turn the back of your mobile towards the run or a lamp.
