Best Smart Scale for Body Fat Tracking

Weight alone tells you almost nothing during fat loss. A scale that tracks body composition tells you whether you're losing the right kind of mass.

How we picked

We ranked by number of electrodes (segmental > foot-only), app quality, trend visualization, and multi-user support.

#1 Editor's pick
Withings

4.7
$399
- Segmental readings (leg vs arm vs trunk fat/muscle)
- 6-lead ECG built in — screens for atrial fibrillation
- Best-in-class Health Mate app with automatic Apple Health / Google Fit sync
