How to choose
If you need clinical-grade insights, choose the Withings Body Comp for multi-frequency BIA and visceral fat estimation. For casual tracking, single-frequency BIA in the Body+ or Renpho is sufficient.
If you own a Garmin watch, the Index S2 is the only logical choice for unified data. For other users, prioritize scales that integrate with Apple Health or Google Fit, such as the Withings or Eufy.
The Eufy P3 and Renpho offer all features without a subscription. The Withings Body Comp may require a subscription for full history access to advanced metrics, adding to its higher upfront cost.
The Renpho supports unlimited user profiles, making it ideal for large families. The Garmin Index S2 and Eufy P3 support 16 profiles, while the Withings scales typically support fewer users depending on the model.
Our verdict
The Withings Body Comp is the best smart scale for weight loss in 2026 due to its multi-frequency BIA, segmental analysis, and unique nerve health sensors. For Garmin users, the Index S2 offers the best integrated experience, while the Eufy P3 provides the best value for those avoiding subscriptions.
