HeartPeace funktioniert nicht

Although the camera heart rate monitor works fine it's recommended to use a BLE heart rate monitor because it's more accurate, allows more freedom of movement, consumes less battery, and works while the screen is turned off.  You can use the back camera as a heart rate monitor but it's recommended to use a BLE heart rate monitor because they are more accurate, allow more freedom of movement, work while the screen is turned off and consume less battery.  The feedback is provided by measuring your cardiac coherence using heart rate variability analysis algorithms that determine your parasympathetic vs sympathetic nervous system activation.  Feedback is also presented using sounds so headphones are recommended, if you have low inner peace you will hear a crowd sound but if your inner peace is high you will hear monks meditating and deep sounds.  You can select in preferences the back camera to measure heart rate from your finger.  Only heart rate monitors that accurately measure R-R intervals and have Bluetooth 4. 0 (BLE) are supported.  Therefore, a heart rate monitor is required.  diese App helps you to meditate by providing real-time feedback about your inner peace.  The feedback is given by displaying an animation that resembles your inner state.  The more inner peace, the bigger, slower, and blueish the animation will be.  Place your finger gently over the back camera and flash and try not to move it much.  To better focus on breathing is advised to sit down, use headphones, and close your eyes to minimize distractions.  The app has option to integrate with the Health app by storing sessions as mindfulness sessions.  More info about compatible monitors in settings.
