This application 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 change and the Application calculates your heart rate.
It works in a similar way as a medicalpulse oximeter but without a dedicated light source.
Place your left index finger gently over the camera lens. 'Press' button. Your current heart rate will be displayed in a few seconds.
