Heartthrum – Pulse Monitor

Heartthrum turns your phone into a simple pulse monitor. Place your fingertip on the back camera and see your heart rate in about 40 seconds.

Completely free. No ads. No subscriptions. No in-app purchases. No account. Your data never leaves your device.

MEASURE

Place your finger on the camera and flash. Heartthrum reads the tiny color changes in your fingertip caused by your heartbeat and shows your pulse with a live waveform.

TRACK YOUR WELL-BEING

Save each measurement with an optional context (resting, after activity, morning, evening) and how you feel. Follow your trends by day, week, or month.

BREATHE

Relax with guided breathing at about six breaths per minute. Choose 1, 3, or 5 minutes.

PRIVACY FIRST

Heartthrum collects no data at all. There are no trackers, no analytics, and the app does not even have internet permission. Everything stays on your phone.

Important: Heartthrum is not a medical device. Measurements are for wellness and general well-being purposes only and do not replace professional medical advice.
