How to Scan

Follow these simple steps to perform your non-contact health scan

01
Open Camera
Click OPEN CAMERA and grant camera access.
02
Position Face
Sit comfortably in a well-lit space facing the camera.
03
Enter Body Data
Input Height & Weight for precise BP calculation.
04
Select Meal Mode
Choose Post-Meal or Fasting for Glucose assessment.
05
Start Recording
Click RECORD. Don't blink and stay stable, look at the camera.
06
View Results
Hold steady until scan completes to see your 12 vitals.
FACE POSITIONING: Ensure your face is properly aligned inside the three yellow guide boxes (forehead in the top single box, cheeks in the lower adjacent boxes).
STABILITY ADVICE: Don't blink and stay stable, look at the camera directly throughout recording for accurate signal capture.
Best Accuracy Tip: Keep constant ambient lighting, avoid direct backlighting, and minimize facial movements during the measurement.
