HeartPeek: Heart Rate Monitor

HeartPeek is a heart rate monitor that uses your phone camera. Rest your fingertip on the lens, and in about 30 seconds you see your pulse in BPM, with the live heartbeat wave drawn as you measure.

No account, no sign-up and no paywall before your first reading: tap the heart and measure. HeartPeek checks the signal quality of every reading and tells you honestly when it is good, fair or too weak, so you never get a made-up number. Your readings stay on your phone.

HEART RATE HISTORY AND TRENDS
- Every reading saved with its time, signal quality and pulse wave
- Your daily average, lowest and highest heart rate at a glance
- A clear trend chart for your resting heart rate
- Tags such as resting, just woke up, after exercise, before sleep or after coffee, so resting is compared with resting

BLOOD PRESSURE LOG
Keep your blood pressure next to your heart rate. Type in the numbers from your own blood pressure monitor in two taps: systolic, diastolic and pulse, with arm, position, tags and a note.
- Colour bands based on the American Heart Association categories, for information only
- Day, week and month charts with morning and evening averages
- Daily morning and evening reminders
- A clean PDF report to show your doctor, and CSV export
HeartPeek does not measure blood pressure. It only keeps the values you enter.

HRV AND STRESS CHECK
Take a one minute check to see your heart rate variability (HRV) and a simple stress estimate from 0 to 100, shown as low, normal or high.
- HRV as RMSSD and SDNN, from the beat-to-beat intervals of your pulse
- Stress compared with your own usual HRV and resting pulse once you have a few checks
- Movement or a lifted finger? You get a clear measure again message instead of a guessed number
- A one minute guided breathing exercise after a high result, then measure again
- HRV and stress trend charts next to your heart rate
The HRV and stress values are wellness estimates, not medical measurements.

HOW TO GET A GOOD READING
Sit down and rest for a minute, cover the back camera and flash with one fingertip, touch lightly and keep your hand still. Warm hands give the clearest heartbeat signal.

IMPORTANT
HeartPeek is for general wellness and fitness only. It is not a medical device and does not diagnose, treat or prevent any condition. The camera measures heart rate only, never blood pressure or blood oxygen; blood pressure entries are values you type in, and their bands are for information only, not medical advice. Readings can vary between phones. If you feel unwell, contact a doctor.
