Scan your face right now.

Point your camera at your face, hold still for 30 seconds, and watch structured vitals stream out: heart rate, HRV, SpO₂, respiration, stress. No account. No upload. Pure on-device rPPG. The same pipeline powers apps used by 4 million people a month.

Demo mode

Tap start. Stay still. Get numbers.

This is a guided preview that simulates the 30-second scan so you can see what the SDK emits. The real thing runs the same way — just with your actual pulse driving the waveform.

What you'll see

Four of the thirty metrics a real scan returns.

The numbers below update live during the demo. In production the SDK emits 30+ fields plus per-field confidence and a signal-quality score.

How it works

Three steps, thirty seconds.

We track tiny colour changes in the skin of your face caused by each heartbeat. The math is called remote photoplethysmography — rPPG. It's entirely passive. You just sit still.

Step 01 · 2 seconds

Look at the camera

Frame your face inside the ring. The SDK checks lighting, sharpness, and whether your whole face is visible. If any of those fail, it waits.

Step 02 · 30 seconds

Stay still

Breathe normally. Don't talk. The SDK samples 90 frames per second, tracks landmark points, and extracts the pulse waveform from your forehead and cheeks.

Step 03 · under 1 second

Get structured vitals

On-device neural nets convert the waveform into heart rate, HRV, respiration, SpO₂, stress, and 25+ wellness markers. You get a clean JSON object.

Privacy, by construction.

This demo asks nothing of you. No email. No file upload. No telemetry hop to a server in another country. Here's exactly what happens while you scan:

  • No video is stored. Frames live in RAM for a few seconds, then they're gone.
  • Inference runs on-device — WASM in your browser, CoreML on iOS, TFLite on Android.
  • No signup, no cookies, no fingerprinting required to try the demo.
  • The finished vitals stay on this page. You can screenshot them or close the tab.
  • HIPAA BAA available for production use — but for this demo it doesn't matter.
