3-minute analysis

HRV Spot Check

A fingertip scan of your heart rate and heart-rate variability, right from your phone's camera.

1. 1 Cover the camera and flash. Place your fingertip gently over the rear camera and flash.
2. 2 Hold still for 3 minutes. Breathe normally and rest your hand on a table if you can.
3. 3 Wait for the ring to complete. Keep your finger in place until the countdown ring finishes.

Not a medical device. For personal curiosity only, not diagnosis or treatment.

Cover the lens and flash with your fingertip pad

This camera has no flash the page can control. Turn on your phone's flashlight yourself (or use a bright lamp), then cover the lens and the light with your fingertip.
