HEARTshape - Pulse and Fitness

HEARTshape visualizes your pulse like never before. It uses your device camera and flash to measure heart rate and reveals heartbeat-by-heartbeat changes, beat-to-beat intervals, and beat distribution in real time. See how blood flows with each pulse and compare your resting rate to the general population.

Features include an optical measurement via the camera, a live BPM readout, a trend graph showing heart rate changes per beat, beat-to-beat interval tracking, HealthKit integration for longer-term insights, and optional haptic feedback on supported devices.
