Pulse: Heart Rate Monitor

Pulse is a heart rate monitor that uses your phone camera. Cover the rear camera with a fingertip, hold still, and in about 30 seconds you get your BPM, a live pulse waveform and your heart rate variability. No chest strap, no smartwatch, no account.

MEASURED WITH THE CAMERA
• Real-time BPM from the rear camera and torch
• Live pulse waveform, signal-quality badge and finger detection
• HRV: RMSSD, SDNN and pNN50
• A stress score and an energy score with every measurement
• Tag a reading — Resting, Workout, Morning, Stress — and add a mood or a note

LOGGED BY HAND, IN ONE PLACE
• Blood pressure log with automatic AHA/ACC 2017 classification

AI HEALTH REPORT
A written report over 7, 30 or 90 days: a 0–100 health score with a breakdown per area, red-flag screening, one narrated section per body system, ranked next actions and a list of what to raise with a clinician. Generated entirely on your device from your own readings — no network, no account.

HEALTH CONNECT
Pulse syncs with Health Connect both ways — heart rate, HRV, blood pressure, blood oxygen and weight. Import the history you already have, and write every new heart rate measurement back so the rest of your health apps see it.

PRIVATE BY DESIGN
Your readings never leave your phone. No sign-up, no server, no analytics on your health data. The health report is written on-device.

Pulse is a wellness tool, not a medical device. It measures heart rate and HRV from the camera; blood pressure, blood oxygen and weight are values you enter yourself. Those estimates, the stress and energy scores and the blood pressure classification are for reference only and must not be used to diagnose, treat or monitor any medical condition. If you feel unwell, contact a healthcare professional or emergency services.
