Frequently asked questions
How does a smart scale measure body fat percentage?
Smart scales use bioelectrical impedance analysis (BIA) by sending a tiny electrical current from foot pads up through your legs. The current passes faster through muscle and water than fat, and the scale uses the resistance to estimate body fat percentage.
Are smart scales accurate for measuring body fat?
Consumer smart scales are reasonably accurate for tracking trends but may not be as precise as DEXA scans or hydrostatic weighing. However, many models like Withings show good correlation with clinical methods, especially if used consistently under similar conditions.
Can multiple users share one smart scale?
Yes, most smart scales support multiple user profiles. Many automatically recognize users based on their weight history, and the data is synced to individual accounts in the app.
Do I need to sync my smart scale every time I weigh in?
It depends on the scale. Bluetooth scales require you to open the app nearby to sync, while Wi-Fi scales sync automatically when you step on them. Some scales also have memory to store readings until your phone is nearby.
What factors can affect body fat readings?
Hydration levels, time of day, recent exercise, food intake, and skin temperature can all influence readings. For consistency, weigh yourself at the same time each day, preferably in the morning before eating or drinking.
Are smart scales worth it for weight loss?
Yes, they can be valuable tools for tracking progress beyond weight. Seeing changes in body fat percentage and muscle mass can provide motivation and help refine your diet and exercise plan for better results.

The Withings Body Comp takes the top spot for its exceptional accuracy and comprehensive health insights, making it the best choice for data-driven users.
