Understanding Bioelectrical Impedance Analysis (BIA) and Accuracy

All Wyze scales use Bioelectrical Impedance Analysis (BIA) to estimate body composition. BIA works by sending a weak, safe electric current through your body to measure resistance, which varies between muscle, fat, and water. This data, combined with your personal info (age, height, sex), helps calculate metrics like body fat percentage and muscle mass.

Note: Home-use smart scales like Wyze are designed for reference and trend tracking. Measurements may differ from professional medical devices or gym equipment due to different methodologies. For best accuracy:

• Use the scale barefoot on a hard, flat surface.
  
• Keep feet clean and slightly moist.
  
• Avoid moving during measurement.
  
• Ensure personal data in the app is accurate.
