Why we chose this
We've used Withings scales for nearly a decade, and the Body Scan is the first one that genuinely changed how we think about the data. The segment composition is medically useful (track muscle mass changes by limb), the ECG is the cheapest FDA-cleared option, and the trends presentation is the right design. For data-driven health tracking, this is the home device we'd buy.
The review
Withings's flagship scale is the only consumer device we know of that combines weight, segment-by-segment body composition (legs, arms, torso individually), a six-lead ECG, vascular age estimation, and a small nerve-health screening. The retractable handle is the trick — you grip it during the measurement, completing an electrical circuit that lets the scale read upper-body composition and heart rhythm in a way a no-handle scale can't. The data flows into Apple Health, Google Fit, and Withings's own Health Mate app, and the ECG is FDA-cleared for atrial fibrillation detection. The display is large, color, and shows weight trends rather than just the current number — which is the right design for actual behavior change. It's a $399 scale, which is a lot, but for people tracking serious cardiovascular or metabolic goals, the data depth is closer to a clinic visit than a bathroom appliance.
