FAQ

  • Is this medical advice? No-always talk to your clinician for personal decisions.
  • Do I need an account? No-free without registration.
  • Is my data saved? Not by us-results live in your session until you refresh.
  • Why does my number differ from the doctor’s office? Different formulas, timing, and equipment-use one method consistently for trends.
  • Can athletes use BMI? Often misleading for muscular builds-pair with performance and body-composition tools.
