Try OCTON · no signup required

Read your vitals from a 30-second camera scan.

OCTON uses remote photoplethysmography to read your heart rate, HRV, and oxygen saturation from the tiny brightness changes blood pulses create in your skin or fingertip. Your video stays on your device — we only receive the aggregated colour signal (~22 KB). No signup required.

Optional · clinical-grade accuracy

Pair your Bluetooth devices for ground-truth readings.

Pair a BP cuff, pulse oximeter, or thermometer to complement the camera scan. OCTON treats the device reading as ground truth and uses it to calibrate the rPPG model for future scans.

Browser not supported

Web Bluetooth is available in Chrome / Edge / Opera on desktop (Mac, Windows, Linux) and on Android. Use one of those browsers, or enter readings manually below.

Step 1 · Choose your capture mode

Step 2 · How to capture

1. On your phone, place your fingertip gently over the rear camera lens.
2. We'll turn the flash on (if your browser allows it).
3. Hold still for 30 seconds. Light pressure only.

Honest disclosure

Camera-based vitals are decision-support, not a substitute for a medical-grade BP cuff, pulse oximeter, or thermometer. Anything abnormal — call your clinician. Body temperature is not measurable from a visible-light camera.

Heart rate (rPPG) is clinically validated. SpO2 and blood pressure are surfaced as research-grade with explicit confidence pills.
