Xiaomi - Body Composition Scale S400

The Body Composition Scale S400 measures weight along with body fat, muscle mass, bone mass, BMI, and other body composition metrics using built-in bioelectrical impedance sensors. It syncs readings automatically over Bluetooth to a companion app, building a long-term history that makes it easy to track progress over weeks and months. Support for multiple user profiles lets an entire household track their own metrics on the same scale without mixing up data. A tempered glass platform with a slip-resistant finish and four high-precision sensors deliver consistent, accurate readings every time. Quick step-on activation and auto-calibration mean results are ready within seconds, with no buttons to press before stepping on.
