Accuracy & Limitations

Depending on product version and scan quality, moonScan may estimate or interpret:

• heart rate;
• heart rate variability-style metrics;
• scan quality;
• physiological strain;
• recovery readiness;
• sleep-related recovery signals;
• changes relative to your personal baseline.

moonScan does not directly measure:

• sleep stages;
• sleep architecture;
• blood pressure;
• blood glucose;
• body temperature;
• disease state;
• emotional stress;
• mental health conditions;
• arrhythmia;
• cardiovascular disease;
• metabolic disease;
• insurance risk;
• medical fitness for work.

Camera-based physiological sensing depends on signal quality.

If there is too much movement, unstable lighting, poor framing, weak signal, unstable timing, or low confidence, moonScan may show a limited result or no result.

This is intentional. A withheld result is better than a misleading result.

Heart rate is usually easier to estimate than HRV.

HRV depends on reliable interval timing. If timing quality is weak, moonScan may withhold HRV-style insights or interpret them cautiously.

HRV is also highly context-dependent. It can be affected by sleep, exercise, alcohol, caffeine, illness, hydration, stress, breathing, menstrual cycle, posture, medication, and time of day.

Recovery is not one directly measured number.

moonScan recovery insights are inferred from scan signals, signal quality, recent patterns, and baseline-relative changes where available.

Recovery insights should be treated as wellness guidance, not medical truth.

A single scan can reflect your current physiological state, but trends are more meaningful than one result.

moonScan becomes more useful when used consistently under similar conditions.

Do not use moonScan to make medical decisions.

If you have symptoms, feel unwell, or are worried about your health, contact a qualified healthcare professional.
