⚠️Wellness estimate, not a medical device. This measures your real pulse from the camera. It is not for diagnosis — see a clinician for medical decisions.
Which lens & finger: use the pad of your index finger to cover the main (wide) camera — the lens nearest the flash. Easiest: rest your fingertip flat over the whole camera bump so it fully covers that lens and the flash. Press gently and hold still. (We also use the mic to estimate breathing — allow mic if asked.)

How to scan
- Tap Begin Bio Scan and allow the camera (and mic, for breathing).
- Cover the main (wide) lens nearest the flash with your index fingertip — or just rest your finger over the whole camera bump. See the diagram above.
- Hold the phone still and breathe normally for ~25 seconds. You'll get heart rate, breathing, HRV, a calm/stress read, steadiness, and a plain-language summary.
Method: photoplethysmography — the camera reads tiny color changes in your fingertip as blood pulses through it. Every number here is computed from your real signal. No camera, weak signal, or too much movement → it says so, never a fake number.
