Your camera, your call.
HalfBeat estimates pulse, breathing and talking from your webcam, then shows how fast your body settles after a hard interview question.
By continuing you consent to your webcam being used for this session. You can withdraw at any time by stopping the app.
Framing check
Face the camera, upper chest in frame, ordinary room light on your face — no backlight behind you. Pulse works best when you are still; breathing needs your chest visible.
waiting for the SDK…
Sit still, breathe normally, do not talk. This is how the app learns what your calm looks like.

“back down” = seconds from your peak until pulse stayed inside your baseline band. Resolution is one 12-second pulse window; a dash means it never returned inside the window.
