Cira combines remote photoplethysmography (rPPG) and ballistocardiography (rBCG) to extract heart rate, HRV, blood pressure and breathing rate from a 30-second face video.
A neural 3D face-tracking model isolates skin pixels and removes motion artefacts. A 7-component Estimation Quality Index validates every reading. Accuracy has been peer-reviewed and validated across 33 countries.
All face processing runs on-device — no video ever leaves your browser.
