Your Camera Can Read Your Heartbeat
Every heartbeat pushes a faint wave of light through your skin. Your browser camera can detect it — and from that single signal, measure your heart rate, breathing, and stress level in real time.
Remote photoplethysmography — the same science behind hospital pulse oximeters. Your camera detects tiny color shifts on your skin caused by blood flow. All processing runs in your browser. Nothing is recorded. Nothing leaves your device.
  • 60-second scan — heart rate, HRV, and breathing in real time
  • Completely private — nothing is uploaded or recorded
  • No app, no wearable, no account required
  • We ask because it's your camera — not every site does
