Overall Value

Indicates the balance between product quality, features, and price.

The very high price is a major hurdle. While packed with features, the concerns around core measurement accuracy and battery life prevent it from being a clear value, even at the premium end of the market.

Premium pricing offset by unique cardiovascular metrics and multi-year firmware support; no mandatory subscription.

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+).

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

Expert Review Summary

Our clinical assessment and verdict for each device

Withings Body Scan

Recommended

"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.

Recommended

"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.
