Who Should Buy This#
The Withings Body Smart hits a sweet spot for people who want lab-style body insights at home without paying for a connected gym or a monthly plan. It delivers eight-metric body composition, multi-user tracking and a polished app that brands often gate behind subscriptions or charge $150-plus for.
Most cheap smart scales give you a wobbly weight reading and a clunky app. This one feels like a finished product, from the rigid glass platform to the trend graphs that actually help you make decisions.
Perfect for:
- Weight-loss trackers who want to confirm they're losing fat and keeping muscle, not just dropping water
- Strength and gym-goers who need muscle-mass and lean-mass trends to judge whether training is working
- Busy families who want one scale that quietly recognizes up to eight people and files each profile separately
- Data-minded users already in Apple Health, Google Fit or Fitbit who want clean automatic syncing
Eight-Metric Body Composition#
The Body Smart measures weight plus body fat percentage, muscle mass, bone mass, lean mass, total body water, visceral fat index and basal metabolic rate. That's eight data points from a single 15-second step-on, instead of the one number a basic scale gives you.
This matters because weight alone lies. Lose four pounds and the scale can't tell you whether it was fat or muscle. The Body Smart shows the split, so a steady weight with falling fat and rising muscle reads as real progress rather than a plateau.
Readings come from bioelectrical impedance, the same technique used in gym body-composition machines. Treat the absolute numbers as a guide and the day-to-day trend lines as the real signal.
0.1 lb Precision and Auto User Recognition#
Weight is measured to 0.1 lb (50 g) resolution, fine enough to catch the small weekly shifts that matter on a long fitness arc. Coarser scales rounding to half a pound can hide two weeks of genuine change.
The scale automatically recognizes up to eight users by their weight and body profile, so each person just steps on and their data files itself. No tapping, no choosing a name, no mixing your numbers with a partner's. For households, that removes the single biggest reason shared scales go unused.
Color Screen and Health Mate App#
A 2.8-inch, 320 x 240 color screen sits on top of the platform, showing your weight, a trend arrow and a customizable daily check-in such as the weather or step count. It's readable at a downward glance, even first thing in the morning.
Behind it, the Withings Health Mate app is the real strength. It turns raw readings into clear trend graphs, goals and a weight-trajectory view that smooths out daily noise. Crucially, weight, body fat, muscle mass and BMI are all free. A Withings+ subscription adds coaching and deeper insights, but you are never blocked from your own core numbers.

Connectivity and Battery Life#
The Body Smart syncs over both Wi-Fi (2.4GHz 802.11 b/g/n) and Bluetooth. Connect it to Wi-Fi and every weigh-in uploads automatically with your phone nowhere nearby; prefer to stay off your network and you can sync directly over Bluetooth instead.
It plays nicely with the wider ecosystem too, pushing data into Apple Health, Google Fit and Fitbit so your weight trend lives alongside the rest of your activity. Power comes from four AAA cells rated for about 15 months, so you set it up once and largely forget it.
Design and Build Quality#
The platform is high-strength tempered glass measuring 12.8 x 12.8 inches with a slim 1.1-inch profile, so it sits low and feels planted underfoot rather than tippy. The weight range spans 5 to 200 kg (9 to 440 lbs), covering everyone from a baby weighed in arms to most adults.
The black finish looks clean in a bathroom, though like any glossy glass scale it shows dust and footprints, so expect an occasional wipe-down. The circular brushed center and minimal branding keep it from looking like a gadget.
