How it works
Your iPhone's camera and flash detect the tiny color changes in your fingertip with every heartbeat.
- Open the app. The camera and flash turn on automatically.
- Cover the rear camera and flash gently with your fingertip and hold still.
- Watch your pulse appear in real time while the app measures for 25 seconds.
- Save your result with what you were doing and follow your trends over time.
