Eufy Smart Scale P3 Review: The Best Budget Body Composition Scale

Design & Build Quality

The Eufy Smart Scale P3 is a 30 × 30 cm tempered glass scale with an LED display and four stainless steel electrodes. Available in Black and White, it is visually clean without being particularly refined — functional rather than elegant.

At this price point, the build trade-offs are apparent on close inspection. The glass feels slightly thinner than Withings, the electrode finish is adequate rather than premium, and the LED display — while readable — lacks the crispness of Withings’ display strip. At 1.5 kg, it is lighter than the Withings scales and can slide on smooth bathroom tiles if nudged; rubber feet help but do not fully eliminate this.

None of this affects function. The scale measures reliably, fits in a bathroom corner, and the glass cleans easily. The build quality is appropriate for the price — you are paying for the data features, not the materials.

Setup & Ease of Use

Setup is straightforward. Download the EufyLife app, create an account, and follow the Bluetooth or WiFi pairing guide. Bluetooth pairing is faster; WiFi setup requires entering your network credentials but enables background sync.

The EufyLife app handles up to 16 user profiles. User recognition works by weight and composition history in the same way as Withings — the scale identifies which profile to assign the measurement to automatically. This works reliably for households with meaningfully different user weights.

Day-to-day interaction is simple: open the EufyLife app, step on the scale, and measurements sync within seconds. If you regularly forget to open the app before stepping on, some readings may need to be manually synced on next app open.

Measurement Accuracy

The P3 uses foot-to-foot single-frequency BIA, the standard for consumer scales. It measures weight to 0.1 kg, which is precise and consistent. The body composition metrics — body fat, muscle mass, bone mass, water percentage — are estimates with the same inherent ±3–5 percentage point margin vs DEXA that applies to all consumer BIA devices.

At the budget tier, there is slightly more day-to-day variability in BIA readings compared to premium scales. This reflects electrode quality, measurement circuitry, and calibration rather than any fundamental difference in the BIA method. The trend picture over weeks is still meaningful; individual readings require slightly more caution than on Withings hardware.

Use athlete mode (settable in the app profile) if you train five or more times per week — standard BIA formulas overestimate body fat for high-muscle-mass users, and the correction meaningfully improves accuracy in this group.

Features & Insights

The P3 measures 16 metrics:

Weight, BMI, body fat %, fat mass, lean body mass, muscle mass, skeletal muscle mass, muscle rate, protein %, bone mass, bone density, body water %, subcutaneous fat, metabolic age, visceral fat index, and basal metabolic rate (BMR).

That is a longer list than Withings Body+ or Garmin Index S2, though some of these are derived calculations (BMR from muscle mass, metabolic age from overall composition) rather than independent measurements. The underlying BIA data that drives all of them is the same single-frequency measurement.

What to focus on from the 16: Weight, body fat percentage, muscle mass, and body water are the four metrics with the most direct use. The derived metrics (metabolic age, visceral fat index at this price tier) are directional rather than clinically meaningful.

Athlete mode is practically valuable for trained users — it is not universal among budget scales and distinguishes the P3 from the Renpho and similar budget competitors.

App & Software

The EufyLife app is clean and functional but a step below Health Mate in design and analytical depth. Weight and body composition trends are available at weekly and monthly views. The interface is straightforward: your latest reading at the top, trend graph below, metric breakdown accessible via tabs.

What works well:

• Clear, uncluttered design with good readability
• Easy multi-user profile management
• Fitbit integration is a genuine advantage not available from Withings
• Apple Health and Google Fit sync are reliable

Where it falls short:

• Trend overlays (e.g. fat vs muscle comparison over 90 days) are absent
• Insight commentary is minimal — the app shows the numbers but provides little context
• Historical data analysis is limited compared to Health Mate’s depth

Data Privacy

EufyLife is an Anker Innovations brand (based in Shenzhen, China). User data is processed on servers in the United States and China. Anker’s privacy practices have come under scrutiny in the past regarding data handling for their security camera products (Eufy Security). The scale app collects biometric data; the privacy policy permits sharing with analytics providers and third-party services. Users who are cautious about biometric data sharing with Chinese-headquartered companies should consider the Withings Body+ instead. Data deletion requests can be made via the app but the process is less straightforward than GDPR-native Withings.

Platform Compatibility

The standout here is Fitbit integration — the EufyLife app connects directly to Fitbit, automatically uploading weight and body composition data to the Fitbit app. This is not available from Withings or Garmin scales and makes the Eufy P3 the natural companion for Fitbit device users who want a smart scale.

Subscription & Pricing

At £49.99, the Eufy P3 is the best-value starting point for body composition tracking. No subscription is required, and no features are gated behind a paywall — 16 measurements, all app functions, and all integrations are included in the hardware purchase.

The value case is strong when the alternative is either paying £99.95 for the Withings Body+ (twice the price) or paying £29.99 for the Renpho (similar spec but fewer integrations, no athlete mode). The Eufy P3 sits in a sensible middle position.

Final Verdict

The Eufy Smart Scale P3 is the best budget smart scale for users who want body composition data, Fitbit integration, and no ongoing subscription costs. The 16 measurements, athlete mode, and broad platform compatibility pack more value into £49.99 than any direct competitor at this tier.

The trade-offs are real: app depth and measurement consistency sit below the Withings Body+ level, and the data privacy considerations from Anker’s history warrant awareness. For users for whom these are not dealbreakers, the P3 delivers solid tracking value. For anyone who wants a genuinely premium long-term experience, the Withings Body+ at double the price is worth the investment.

Who Should Buy?

Buy the Eufy Smart Scale P3 if:

• Your budget is under £60 and you want more than basic weight tracking
• You use a Fitbit device and want native scale integration
• You train regularly and want an athlete mode for more accurate body fat readings
• No subscription costs are non-negotiable

Buy the Withings Body+ instead if:

• Long-term data quality, app depth, and WiFi convenience are worth £50 extra
• You use Apple Health as your primary health platform and want the best integration

Buy the Renpho Smart Scale instead if:

• Your budget is closer to £30 and you just need the basics with a reasonable app
