The Withings Body Smart and the RENPHO Bluetooth Body Fat Scale are two connected scales that track weight and body metrics through an app. This comparison helps you see which one fits your day-to-day tracking best.

This comparison covers the Withings Body Smart: do not confuse it with the Body Scan and Body Comp ranges. The RENPHO compared here is the RENPHO Bluetooth Body Fat Scale, corresponding to the Elis 1 model.

This comparison is based on documented sources only: the published product sheets and the manufacturer-announced specifications. We have not run independent tests and we make no body-fat accuracy claims. Current pricing can change, so check both before deciding.

Strengths

  • Wi-Fi and Bluetooth connectivity with the Withings app
  • Body-composition estimates via bioelectrical impedance (BIA)
  • Withings app ecosystem, suited to long-term tracking

Limitations

  • Body-composition measurements are estimates, not clinical measurements
  • Some features may depend on the app and a Withings account
  • Check phone compatibility and the number of supported users

Strengths

  • Bluetooth-connected scale with companion app
  • Tracks multiple body metrics over time
  • Easy to integrate into daily routines

Limitations

  • Impedance readings are estimates, not medical measurements
  • Results depend on consistent conditions and regular use
  • Check the manufacturer sheet for capacity and accuracy

In summary

Both scales track weight and body metrics in an app, and both rely on impedance estimates — never clinical measurements. The Withings Body Smart adds Wi-Fi on top of Bluetooth and leans on the Withings ecosystem. The RENPHO works over Bluetooth with its companion app, built for simple everyday tracking.

Verdict

Choose the Withings Body Smart if you want a Wi-Fi + Bluetooth scale integrated into the Withings ecosystem for long-term tracking. Choose the RENPHO if a Bluetooth scale with a companion app is enough for your tracking. Both answer the same basic need: neither is universally better, and neither replaces medical advice. Before deciding, check phone compatibility and the current prices on the official sheets.
