Listen to your own heart beat. HearBeats streams your live heart rate from Apple Watch to your iPhone, which plays a synthesized stethoscope "lub-dub" in real time, at exactly your current rate. No account, no data collection — your heart rate goes straight from your Watch to your phone and nowhere else. • Live mode: pairs with Apple Watch for real-time heart rate sonification • Demo mode: hear how it works without a Watch • Mix with your music or listen on its own, with adjustable heartbeat volume • Nothing is saved to Health or anywhere else — the workout session used to read your heart rate is discarded • Feel your heartbeat: haptic taps on iPhone and Apple Watch, in time with every beat
