Body Fat % Accuracy

Indicates how accurately the scale estimates body composition metrics such as fat, muscle, and water levels

In our 12-participant test, body fat percentage readings were within a mean absolute percentage error of 14.8% compared to corresponding DEXA scans performed within 48 hours.

+1% better body fat % accuracy

Consistently measures within a 15-20% deviation from DEXA scan results for users with 15% or higher body fat. Deviation increases to 20-30% with users with lower body fat.

Muscle Mass Accuracy

Indicates how accurately the scale measures muscle mass compared to true body composition values.

In our 12-participant validation, total lean/muscle mass estimates matched DEXA within a mean absolute percentage error of ~14.0%; same-day repeat tests (3 runs) varied by ≤0.3 kg.

+3% better muscle mass accuracy

Consistently measures within a 15-20% deviation from DEXA scan results for users with 15% or higher body fat. Deviation increases to 20-35% with users with lower body fat.

Segmental Analysis

Indicates the scale’s ability to measure and differentiate body composition across specific regions such as arms, legs, and torso.

In a 12-participant comparison to DEXA regional values, segmental (arms, legs, trunk) lean-mass estimates showed a mean absolute percentage error of ~14–15%, with left–right symmetry differences ≤2% on retest.

InBody Dial H30

Strengths

✓ Superior measurement consistency due to hand and foot electrodes.
✓ Good body composition accuracy compared to DEXA for a home device.
✓ Robust, stable, and durable hardware construction.
✓ Reliable Wi-Fi and Bluetooth auto-sync.
✓ Automatic user recognition works flawlessly for multiple users.

Limitations

× Significantly more expensive than most competitor smart scales.
× Companion app interface is dated, clunky, and unintuitive.
× On-device LCD display looks old-fashioned.

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).

× Premium app content is gated behind an additional subscription (Health+).

Expert Review Summary

Our clinical assessment and verdict for each device

InBody Dial H30

Recommended

"A highly consistent and accurate scale for data-focused users, if you can forgive the dated software and premium price."

The InBody Dial H30 is a specialized body composition scale that uses an 8-point tactile electrode system (feet and hands) with triple-frequency bioelectrical impedance analysis (BIA) to deliver more consistent results than typical smart scales. Our testing confirmed its strong performance, showing a close correlation with DEXA scans for body fat percentage. The hardware is robust and built to last. However, the device is significantly held back by a high price tag, a visually dated LCD screen, and a clunky, unintuitive companion app. While it excels at its core function of measurement, the overall user experience does not feel premium.

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.
