The short answer: Neither scale is universally “more accurate” because accuracy depends on how you use it and what you measure. For raw weight, the Eufy P2 Pro offers 0.1 lb increments and a high-precision sensor, but the Withings Body+ is renowned for its consistency and clinical validation. For body fat and other metrics, both use bioelectrical impedance analysis (BIA), which is inherently approximate. If you want a scale that syncs seamlessly with health apps and has a proven track record, the Withings Body+ edges ahead. If you want a budget-friendly scale with similar features and a smaller price tag, the Eufy P2 Pro is a solid choice.
When we talk about “accuracy” in smart scales, we’re really talking about two things: how close a reading is to your true weight (absolute accuracy) and how consistent it is over time (repeatability). No consumer scale is a medical device, so even the best ones can vary by a few tenths of a pound due to factors like hydration, food intake, and even how you stand.
Both the Eufy P2 Pro and Withings Body+ use strain gauge sensors to measure weight. The Eufy advertises a 0.1 lb (0.05 kg) resolution, while the Withings also offers 0.1 lb resolution. In practice, that means both can show the same level of detail, but the internal electronics and calibration matter. Eufy claims a high-precision sensor, but Withings has a longer history in the health tech space and often receives praise for its stable readings across multiple weigh-ins.
For body composition metrics (body fat %, muscle mass, etc.), both scales use BIA, sending a tiny electrical current through your body. This method is notoriously sensitive to hydration status, skin temperature, and even foot calluses. So if you take a reading after a workout or a big meal, you’ll see different numbers. That’s not a flaw in the scale; it’s the nature of the technology. The best you can do is weigh under consistent conditions.
The Eufy P2 Pro has a sleek, minimalist design with a white or black finish. It’s made of tempered glass, which is common, but some users report that the surface can feel a bit slippery. The display is an LED segment that’s bright and easy to read, but it doesn’t have a backlight that stays on for long.
The Withings Body+ also uses tempered glass but has a more premium look, with rounded edges and a clean, Scandinavian design. It comes in black or white, and the display uses a large LCD with a backlight that can be activated by tapping the glass. The build feels sturdier, and the scale is a bit thicker, which likely houses better internals. If you care about aesthetics, both are fine, but Withings feels more polished.
For durability, both are rated for around 400 lbs (180 kg), but the Withings has a slightly higher weight capacity (up to 396 lbs) and a better weight distribution. The Eufy has a smaller footprint, so if you have large feet, you might find it cramped.
Accuracy isn’t just about the hardware; it’s also about how the data is processed and presented. The Withings Body+ works with the Health Mate app, which is one of the most mature health apps on the market. It syncs with Apple Health, Google Fit, and many third-party fitness apps. You can track trends, set goals, and even get weather-based suggestions. The app also offers a “baby mode” and “athlete mode” for more tailored body composition readings.
The Eufy P2 Pro uses the Eufy Life app (or the older EufyHome app). It also syncs with Apple Health and Google Fit, but the app is simpler. It shows your weight, BMI, body fat, muscle mass, and a few other metrics, but it lacks the depth of Health Mate. For example, Withings provides detailed graphs and explanations, while Eufy just gives you numbers.
When it comes to accuracy, the app can help you interpret trends rather than obsess over single readings. Withings’ app automatically recognizes each user and can handle multiple profiles seamlessly. Eufy also supports multiple users, but it sometimes mixes up readings if two people have similar weights.
In real-world use, the Withings Body+ tends to give more consistent readings. That means if you step on the scale twice in a row, you’ll get the same number almost every time. The Eufy P2 Pro is also consistent, but some users have reported occasional jumps of 0.2-0.3 lbs without any logical reason, which can be frustrating if you’re tracking small changes.
Another factor is how quickly the scale locks onto your weight. The Eufy P2 Pro gives a reading almost instantly, but the Withings takes a second or two longer, which is actually a good thing because it allows the sensor to settle, improving accuracy.
Battery life is also a consideration. The Eufy uses 3 AAA batteries that last about 6 months with normal use. The Withings uses 4 AAA batteries that last up to 18 months. That’s a significant advantage for Withings, as you’ll replace batteries less often.
Pricing can vary, but generally the Eufy P2 Pro is priced lower than the Withings Body+. The Eufy is a budget-friendly option, while the Withings sits in the mid-range to premium segment. That’s a big difference. If you’re on a tight budget, the Eufy is a fantastic value. It gives you all the essential metrics and app integration at a fraction of the cost.
However, if you’re serious about tracking your health long-term, the Withings is worth the extra investment. The build quality is better, the app is more powerful, and the consistency is superior. Plus, Withings has a reputation for software updates that add new features over time, whereas Eufy rarely updates its scale firmware.
Before you decide, also consider that neither scale is a medical device. If you have specific health conditions, you should rely on professional measurements. For general fitness tracking, both are sufficient. If you want to see how they stack up against other models, check out our best smart scales guide for more comparisons.
Neither is truly accurate for body fat percentage because BIA is a rough estimate. However, the Withings Body+ tends to be more consistent in its body fat readings due to better sensor calibration and a more sophisticated algorithm in the app. If you use the scale under the same conditions (e.g., morning, before eating), you’ll see similar trends with both.
No, you should avoid using any smart scale that sends electrical currents (BIA) if you have a pacemaker or other electronic medical implant. The current could interfere with the device. Both Eufy and Withings include warnings about this in their manuals.
Yes, both scales sync with Apple Health and Google Fit. The Withings Body+ also integrates with many other apps like MyFitnessPal and Fitbit, thanks to its robust API. The Eufy P2 Pro has basic sync with Apple Health and Google Fit, but fewer third-party integrations.
