Withings Smart Scale: Track Weight, BMI, and Body Fat Automatically

A Withings smart scale looks like any other bathroom scale, but after you step on it, your weight and other body measurements automatically appear in an app on your phone within seconds. There is no writing numbers down, no manual logging, and no guessing. The data is organized into charts so you can see your progress over days, weeks, and months at a glance.

Depending on the model, a Withings scale can measure not just your weight but also your Body Mass Index (BMI), body fat percentage, muscle mass, and even your bone mass. It does this using a safe, low-level electrical signal that passes through your feet — a technique called bioelectrical impedance analysis. This is painless and takes less than a second.

The free Withings Health Mate app stores all your measurements and shows long-term trends in a straightforward format you can read at a glance. You can set a goal weight and the app will show you how close you are and how your trend is heading. Family members can each have their own profile on the same scale — the scale automatically recognizes different users by weight range.

The Health Mate app connects to Apple Health, Google Fit, and many other health apps, so your weight data flows into your overall health picture without any extra steps.

Withings scales connect to your home Wi-Fi, so data syncs even if your phone is in another room. You step on, you step off, and your numbers are already logged by the time you get back to your phone.
