Pulse: Heart Rate Tracker

Pulse is a simple, local-only wellness pulse checker. Place your fingertip gently over the rear camera and hold still. Pulse estimates your pulse from derived brightness changes in about 30 seconds. A result always prioritizes BPM and signal quality. PRV, estimated breathing rate, and recovery appear only when a longer, denser, Good-quality signal supports them. Add context or how you feel only when it is useful to you. FEATURES Quick camera pulse Use the rear camera and torch on supported devices for a guided pulse reading. Only supported results See BPM and signal quality without empty metric cards. Additional estimates appear only when they were actually derived. Optional context Add resting, after-exercise, or other context and an optional feeling without blocking the result. Local history Save up to 100 readings on this device with available metrics, context, feeling, quality, note, and waveform preview. No account Pulse has no account, backend, ads, analytics, cloud sync, or subscription. Wellness only Pulse is for personal wellness and fitness context only. It is not a medical device and is not for diagnosis, treatment, emergencies, clinical monitoring, or medical decisions.
