- Features ITO-coated surface for improved barefoot accuracy
- Supports integrations with Apple Health, Google Fit, and Fitbit
- Foot-only BIA accuracy varies significantly with hydration levels
- Lacks Wi-Fi connectivity, relying on implied Bluetooth sync methods
- Not reliable for users requiring high-precision visceral fat tracking
Best for: Budget-conscious users in the UK wanting basic body composition tracking without premium costs.
How to choose
Choose Wi-Fi models like the eufy P3 or Etekcity if you want background syncing without holding a phone; select Bluetooth-only models like the eufy C20 only if you prioritize on-device display over remote data logging.
If you track visceral fat or vascular age, the Withings Body Comp is the only option in this list providing those specific multi-frequency BIA estimates; other models limit you to standard weight and body-fat percentages.
Households with more than eight members should avoid the Withings Body Comp due to its eight-user automatic recognition limit; the eufy C20 and P3 offer unlimited profiles, though the P3 may struggle with identity confusion if weights are similar.
If your budget is under £50, the eufy P2 Pro is the only viable option; for comprehensive health dashboards, expect to pay ~£230 for the Withings Body Comp, a 4.6x price difference for added vascular-age metrics.
Our verdict
The Withings Body Comp is the definitive choice for 2026 UK users prioritizing data depth, offering unique vascular-age and visceral-fat metrics with eight-user automatic recognition. Budget-focused users should select the eufy P2 Pro for sub-£50 access to 16-metric tracking, accepting lower precision trade-offs.
Frequently asked questions
Which smart scale supports Wi-Fi background syncing?
The eufy Smart Scale P3 and Etekcity HR Smart Fitness Scale support Wi-Fi connectivity, allowing data to sync in the background without requiring a phone nearby during weigh-ins.
Can these scales track heart rate?
Yes, the eufy P3, Withings Body Comp, and Etekcity HR Smart Fitness Scale all track heart rate as part of their 14-16 metric suites, while the eufy C20 and P2 Pro do not explicitly list heart rate in their primary metric sets.
What is the maximum number of users supported by the Withings Body Comp?
The Withings Body Comp supports automatic recognition for up to eight users, which is a hard limit compared to the unlimited user profiles offered by the eufy C20 and P3.
Are foot-only BIA scales accurate for muscle mass?
Foot-only bioelectrical impedance analysis, used by all listed scales, is generally less precise for muscle mass than handle-based scales; accuracy also varies with hydration levels, particularly noted in the eufy P2 Pro limitations.
