A smart scale can record weight trends, estimate body composition and send readings to a phone app. For UK users, stone display, clear graphs and reliable app support matter as much as the number of metrics.
This guide compares five popular scales by features, price, connectivity and value. Body-composition readings are estimates, not medical measurements. Use our kg to stone converter for readings shown in kilograms.

Check the current Renpho priceThe Renpho Elis 1 is a practical low-cost choice. It tracks weight and body-composition estimates, while its app connects with Apple Health, Samsung Health, Fitbit and MyFitnessPal.
It supports stone display and is easy to use for regular tracking. The app and trend presentation are less polished than Withings.

4. Eufy Smart Scale P2 Pro: Best for Body Composition Detail
Best for body-composition detail
Check the current Eufy priceThe Eufy P2 Pro reports a broad set of body-composition estimates, including body fat, muscle mass and BMI. The Eufy Health app presents results with clear labels and trend graphs.
It uses Bluetooth rather than Wi-Fi, so your phone needs to be nearby during weigh-ins. It supports stone display and works with Apple Health and Fitbit.
Typical price: £50 to £70 on Amazon UK.
Best for: More body-composition detail without a premium price.

5. Withings Body Comp: Best Premium Option
Best premium option
Check the current Body Comp priceThe Withings Body Comp adds advanced body-composition features to the Withings app experience. It supports Wi-Fi sync, stone display and up to 8 users.
The premium price makes sense if you want those extra features. For straightforward weight tracking, the cheaper Body Smart is likely better value.

Best for: People who want a premium scale and a wider set of home health estimates.

Reading Smart Scale Data
Take readings under similar conditions and focus on trends across several weeks. Body-fat, muscle and visceral-fat readings are estimates affected by hydration, food, exercise and the device algorithm.
For height-based context, use the BMI calculator. BMI is a screening measure, not a diagnosis.
