Bottom line

The Withings WS-50 is a highly accurate body-monitoring device geared toward the tech-savvy consumer. The scale automatically transmits readings to a free app for iPhone or Android, and it can track multiple data lines for several family members. Although some might find a few features superfluous (for example, the ability to tweet one's readings), overall, the Withings WS-50 paints a detailed picture of one's health. However, there are those who complain about faulty and defective units and a lack of responsiveness from Withings' customer support team.


A high-tech, accurate performer. The Withings WS-50 Smart Body Analyzer is no ordinary scale -- a high-tech bathroom scale that analyzes and tracks your health by sending measurements wirelessly to your Android or iPhone. From there, you can view graphs and tracking information and use Withings' software to get more health information. A number of expert reviewers and contributors to note that the scale's progress-tracking feature was a great motivator, making weight loss feel more like a game.

Among hundreds of owner-written reviews on, we did find some complaints that the scale offers unreliable and inaccurate readings, even when used on a hard, flat surface.

Ease of use

Setup is a cinch. An expert reviewer at and contributors to agree that the setup for Wi-Fi connection is seamless -- the scale can automatically copy your phone-stored password so there's no need to input it again. "The true beauty of this scale is its convenience. It logs your weight effortlessly for you," one Amazon user says. Another user says that weight capture and BMI measurement take about one to two seconds, while it takes about 10 seconds altogether to gather the data for body fat and heart rate.


Spotty customer service. Withings offers a one-year, limited warranty, although some owners indicate that customer service is slow or completely nonresponsive to emails and phone calls. Some Amazon reviewers report receiving faulty units and being unable to reach customer support for replacements. Battery life is also reported to be an issue for some users, but like the scale's accuracy, opinions are split. One consumer review says, "The Withings website even allows the user to see the estimated battery charge remaining in the scale. After six months, 73 percent remaining. Not too shabby for using the scale, on average, of twice a week."


Appealing, sleek, modern and shiny look. Reviewers agree that the Withings WS-50 is attractive, with an elegant glass surface. A reviewer at praises the scale's "sleek Apple-like design." Its appearance looks modern, in accordance with its technical functionality, and won't detract from any room's décor.
