o CardioWatch can detect your heart beat rate while pressing your finger tip on your backside camera for a few seconds.
o Press the START button to begin recording your heart beat rate. Make sure that you hold your finger on the camera until the app stops recording your heart rate and displays a result.
o For accurate results, make sure that the color inside the top circle that is captured from the backside camera has the same color as the bottom control circle. If your device does not have a backside illumination sensor, be sure to use an external lamp to illuminate your finger so that the captured finger color matches the color in the control circle.
o The results provided by the app are influenced by extrenal factors, such as illumination changes, movements, and so on. Therefore, the results are not always accurate.
