You can record a heartbeat in the Bond Touch app or the companion app on your iOS or Android smartphone.
Simply go to the Bond Heart section and follow the instructions on your screen when prompted to record the heartbeat. Note that the recording process works best in a dark room. Remain still and don’t move your phone around, as ambient light differences will affect the recording process.
Place your finger gently on top of your smartphone’s camera until the flashlight and the camera are completely covered. If the flashlight is hot, place your finger 2mm (the thickness of a 5-cent coin) away from the light, covering the camera.
