HONEST BY DESIGN
BodyIQ gives statistical estimates calculated from the measurements you enter — it is not a medical device, does not analyze your body through the camera, and does not diagnose. BMI and body-fat figures are general wellness indicators, not clinical results. Always consult a qualified healthcare professional for medical decisions.
