Pulse - AI Heart Rate Monitor

NEW: AI signal processing for accurate BPM in ~15 sec. Place your finger on the camera - no wearable needed. Free, private, no account required.

Pulse measures your heart rate accurately in about 15 seconds using only your iPhone camera. No wearable needed. Place your finger on the lens, hold steady, and Pulse delivers a clinically-informed BPM reading powered by AI signal processing.

ACCURATE MEASUREMENT WITH AI Pulse uses photoplethysmography (PPG) - the same optical technique used in medical pulse oximeters - combined with Welch's FFT, a Kalman filter, and harmonic verification to filter noise and surface your true heart rate. Designed for precision, not approximation.
