Pulse: Heart Rate Tracker

A guided camera reading estimates heart rate in about 30 seconds. Available estimates stay local, private, and account-free.

Pulse is a free, ad-free heart rate tracker for quick camera checks and private on-device history.

Place your fingertip over the rear camera and flash, follow the guided check, and hold still while Pulse evaluates the signal. A reading is saved only when the captured pulse evidence passes the app’s quality gates.

FREE, PRIVATE, AND AD-FREE

Pulse has no ads, subscription, in-app purchases, account, analytics, backend, or cloud sync. Derived readings stay on your iPhone. Pulse does not save photos, videos, raw frames, or frame buffers.

CLEAR, SUPPORTED RESULTS

See your estimated pulse in BPM with signal quality. Weak sessions are not presented as successful results, and unsupported wellness estimates stay hidden.

USEFUL LOCAL HISTORY

Keep up to 100 readings on your device. Add optional resting or activity context, how you felt, and a note when it helps you compare similar moments.

WELLNESS ONLY

Pulse is for personal wellness and fitness context. It is not a medical device and is not for diagnosis, treatment, emergencies, clinical monitoring, or medical decision-making.
