Pulse - Heart Rate & BP Log

Pulse turns your phone camera into a heart rate monitor. Cover the rear camera with a fingertip, hold still, and in about 30 seconds you get your BPM. No chest strap, no smartwatch, no account, no ads.

HOW TO TAKE A READING
1. Open Pulse and tap Measure.
2. Rest a fingertip over the rear camera and the torch.
3. Hold still for about 30 seconds while Pulse counts your heartbeats.
4. Read your BPM and your heart rate zone, then tag the reading and add a note.
The camera and the torch are the whole sensor — nothing to pair, nothing to charge.

MEASURED WITH THE CAMERA
• Real-time BPM from the rear camera and torch
• Signal-quality badge and finger detection
• Heart rate zones worked out from your age, so you can see at a glance whether a reading was resting, fat-burn, aerobic or peak
• Tag a reading — Resting, Workout, Morning, Stress — and add a mood or a note

A BLOOD PRESSURE DIARY, AND EVERY OTHER VITAL IN ONE PLACE
These are readings you type in yourself, from your own cuff, oximeter, scales or watch. Pulse keeps them together, charts them and explains what each one means.
• Blood pressure diary with automatic AHA/ACC 2017 classification on every entry
• Blood oxygen (SpO2) log
• Weight log and BMI calculator, in kilograms or pounds
• Manual heart rate entry
• Full history per vital, charted against its reference range
• Reminders, so the diary actually gets filled in

GUIDED BREATHING
• Box breathing, 4-7-8, Coherence (5.5 breaths per minute) and Relax
• An expanding-circle guide with haptic cues and a phase ring
• Session history and weekly minutes

TRENDS AND INSIGHTS
• Daily, weekly and monthly charts for heart rate, blood pressure, weight and SpO2
• Personalised heart rate zones from your age
• Plain-language insights, not just numbers
• Export everything as PDF or CSV

HEALTH REPORT
A written health report over 7, 30 or 90 days: a 0-100 health score with a breakdown per area, flags for values outside their reference range, one narrated section per body system, ranked next actions, and a list of things worth raising with your GP. Generated entirely on your device from your own readings — no network, no account.

APPLE HEALTH
Two-way sync for heart rate, blood pressure, blood oxygen and weight. Import what is already there, and write back everything you record in Pulse.

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, and export is something you choose, not something that happens in the background.

44 LANGUAGES
