Withings WS-50 Smart Body Analyzer Review
Bottom Line

The Withings WS-50 smart scale is a top choice for the tech-savvy user that want's a connected scale to keep track of their weight and more. It's versatile, with both Wi-Fi and Bluetooth connectivity, and the ability to play nice with third party apps -- though reviews say that its own app is powerful enough for most users. Testing shows that the WS-50 is highly accurate when it comes to weight measurements, and no less accurate than other home scales when it comes to measuring body fat. While most users are satisfied, those that run into issues say that customer service is often unresponsive.

  • Accurate weight measurement

Breaking it down


A high-tech, accurate performer. The Withings WS-50 Smart Body Analyzer is no ordinary scale. It's a connected smart scale that can share its measurements via Bluetooth or Wi-Fi. You can use your favorite third party app to track your progress, or use Withings' own app, which draws praise for its usefulness and versatility, including the ability to accept data from other apps and devices. For those with massive self-confidence, the Withings app can even tweet out your progress to the world, if that's something you'd actually like to do. When it comes to measuring weight, no scale does better in expert reviews, and TheSweethome.com calls it the most accurate scale it's tested. It's also one of the few scales that testing shows to be reliable on a variety of floor surfaces and coverings, including carpeting, according to Elizabeth Palermo at Livescience.com. Body-fat measurements, on the other hand, are no more accurate than other home scales -- a limitation of the technology they all use -- in other words, fair at best, though that's still better than many body-fat scales. The scale can also capture and record room air quality and temperature data, and even display that day's weather forecast.

Ease of use

Setup is a cinch -- most of the time. Connected devices often pose challenges to users when it comes to getting that connectivity to actually work, and the WS-50 is not immune from that -- and, no surprise, the challenges are especially steep for those connecting via Wi-Fi rather than Bluetooth. However, if you don't run into those issues -- or can overcome them -- everything else seems to go as smooth as silk. "Setting up the Withings scale was refreshingly simple," says Palermo, who adds that Bluetooth pairing with her smartphone was actually easier than with other smart scales in the Livescience.com test. The WS-50 can automatically track up to eight users, with the initials of the user appearing in one corner of the 2.9-inch backlit display so you know you are using your profile rather than someone else's.


Spotty customer service. Although Withings offers a one-year, limited warranty, some owners indicate that customer service is slow or completely nonresponsive. Reports of units that failed prematurely are not uncommon, though don't appear to be higher than with similar products.


Appealing, sleek, modern and shiny look. Reviewers agree that the Withings WS-50 is attractive, with an elegant glass surface. "We like its sleek all-glass top, which will look up-to-date on any bathroom tile floor for years to come," says Laptop magazine's Mike Prospero.

Scales, Editors of ConsumerReports.org, Not Dated

ConsumerReports.org includes six body-fat scales in its latest round of testing, including the WS-50. The site remains unimpressed with body-fat scales' performance on that measure, but allows that "they offer other features you might like, such as sending your measurements to your computer or smart phone so that you can keep track of your weight." Testing includes ratings for performance when measuring weight and body fat, as well as the repeatability of the measurements, the quality of the display, and ease of use, but the details are only available to subscribers.
