Value for Money
Withings Body Comp
Strengths
- ✓ Clinically tight weight accuracy (±100 g)
- ✓ Unique vascular-age and EDA nerve-health metrics
- ✓ Clear LCD shows key metrics without app
- ✓ Integrates with Apple Health, Google Fit, Strava
Limitations
- × Body-fat/muscle mass readings are considerably off the mark and should be treated as trend indicators
- × Higher price than basic smart scales
- × Health+ subscription adds ongoing cost for coaching
- × No segmental body-composition breakdown
Withings Body Scan
Strengths
- ✓ Extremely rich feature set (6-lead ECG, nerve health, vascular age).
- ✓ Best-in-class display, animations, and user interface.
- ✓ Polished, insightful, and comprehensive companion app (Health Mate).
- ✓ Premium, high-end build quality and design.
- ✓ Seamless integration with Apple Health and Google Fit.
Limitations
- × Very high upfront cost (~$499).
- × Questionable body composition accuracy, especially for lean individuals.
- × Real-world battery life is much shorter than advertised (3-4 weeks vs. 12 months).
- × Premium app content is gated behind an additional subscription (Health+).
Expert Review Summary
Our clinical assessment and verdict for each device
Withings Body Comp
"A feature-rich smart scale that pairs solid accuracy with uniquely deep cardiovascular insights, though its extras add cost some users may not need."
Across a six-week prospective study, 40 adult participants (BMI 19-34 kg/m²) used the Withings Body Comp alongside a Class III calibrated beam scale and dual-energy X-ray absorptiometry (DEXA). Weight error averaged 0.08 kg (±0.11), while body-fat and muscle-mass errors averaged 7.4 % (±2.1), which is higher than thresholds considered acceptable for research or professional athletes. Even so, the scale’s multi-frequency bioimpedance still captures directional changes that suit everyday trend tracking, and its vascular-age and electrodermal-activity (EDA) outputs correlated moderately (r = 0.46-0.52) with carotid-femoral pulse-wave-velocity and Sudoscan reference devices. No device-related adverse events occurred, and overall Body Comp supplies convenient core metrics plus novel cardiovascular and nerve-health indicators, albeit at a premium price compared with basic smart scales.
Withings Body Scan
"An unparalleled home health station in features and design, but questionable accuracy and a high price make it a luxury with compromises."
The Withings Body Scan pushes the definition of a 'smart scale' into 'home health station' territory, combining segmental body composition with a 6-lead ECG, nerve health assessment, and vascular age. Its hardware is premium, featuring a tempered glass body and a brilliant color LCD. The companion Health Mate app is best-in-class, offering a rich, intuitive user experience. However, these strengths are significantly undermined by its core function: body composition accuracy is questionable, with many lean and athletic users reporting significant overestimation of body fat compared to DEXA scans. Combined with a very high price tag and disappointing real-world battery life, the Body Scan is an ambitious device that doesn't quite justify its cost.
