Turn your Android phone into a heart pulse monitor by using the camera to detect subtle changes in the opacity of your finger as your heart beats. The graph of your heart beat is displayed in real time, and is used to calculate the BPM (Beats per minute) of your heart rate. Monitoring your pulse has never been so easy, accessible, and accurate. To use: - place your finger over the camera, - keep your hand still, - wait at-least 6 seconds for an accurate reading. This is a preview release. - **We are currently improving the algorithm for heart beat detection** - If you don't see the graph then please tell us what phone you are using we will fix it asap. Thanks, and enjoy!
