Heart Cam

Heart Rate Monitor (Heart Cam):     Free, instant, and accurate heart rate monitor. How to use our heart rate monitor app: 1. How to measure     * Please launch this app in a bright environment.     * Gently cover the rear camera with your fingertips and keep it still for a few seconds.     * The app will instantly measure your heartbeat waveform and calculate your heart rate. 2. How to set     * The front or rear camera can be selected for measurement. When the rear camera is turned on, the flash can be used together to obtain a good signal-to-noise ratio measurement signal. If a front camera is used, we will disable the flash to avoid discomfort when it comes to the user's eyes.     * You can set the heartbeat sound enabled, and when the app detect a complete heartbeat pulse, it will play a short sound effect.     * Users can set the measurement time by themselves. 3. Historical records     * Users can view the heartbeat records they have measured in the historical records. 4. Reference     * Users can refer to the normal value of pulse rate for each age group.
