1. Guided capture
The experience asks for camera access and guides the user to a stable position with suitable lighting. Lighting, movement and face position affect signal quality; follow the on-screen guidance during the scan.
2. Signal processing and estimation
The measurement technology analyses subtle, pulse-related changes in facial video. Outputs are generated only where the provider supports them and the scan meets relevant quality criteria. Blood pressure is an estimate rather than a direct cuff measurement.
3. Quality and eligibility gates
Results may depend on age, country, consent, device, camera, lighting, motion and provider eligibility rules. A failed or low-quality scan should not be converted into a confident result.
4. Explanation and trends
The interface separates direct estimates, derived wellness indicators and longer-term risk calculations. It explains limitations beside the result and encourages confirmation where appropriate. Compare check-ins taken under similar conditions and remember that gaps provide no reading.
5. Understanding the limits
A successful scan is not a diagnosis. Camera estimates and calculated wellness indicators answer different questions and must be interpreted in context. Use a validated device or healthcare professional to confirm a result when appropriate.
