Very accurate.
Wyze Scale reports weight data within - / + 0.5% of a full scale reading, and Bio-electric Impedance Analysis (BIA) data within - / + 1% of a full scale reading.
This means that if you weigh 150 lbs with a Body Fat Percentage (BFP) of 25%, the Wyze Scale will be accurate within 0.75 lbs and 1%.
Keep in mind
Wyze Scale combines the personal information you entered during set up (gender, age, height) with real time data (weight, body fat) to calculate your body composition measurements.
If you enter incorrect information during set up, your measurements will be incorrect.
