I recently discovered the world of smart scales while researching how to use FSA/HSA funds to buy fitness trackers. I found that some Withings smart scales in particular are marketed as medical devices rather than just stylish fitness trackers. After all, compared to any old scale or smartwatch, smart scales promise detailed body composition analysis. In theory, using data on muscle mass, body fat percentage, and other body metrics, you can tailor your workout and nutrition programs for faster results. Unfortunately, when it comes to what smart scales can tell you, the reality is a bit disappointing .
With all these features that most scales simply don’t offer , the biggest reason to buy a smart scale is simple: the ability to sync your data with your favorite health app. If that sounds promising, we have good news: The Withings Body Comp Smart Scale is currently on sale for $169.95, down 26% from its regular price of $229.95.
This Withings scale is compatible with Health Connect, Apple Health, MyFitnessPal, Strava , and more . Instead of keeping a fitness tracker on your watch for everyone to see, you can do more personalized weigh-ins and get all the same information: heart rate, body composition, bone mass, and, of course, weight . If you find that your readings are consistent enough to track over time, keep weighing and have fun.
If you’re a smart scale fanatic and want to spend your FSA/HSA money on one, the Withings Body Scan Smart Scale is also available for $349.95 (was $499.95). Its standout feature is supposedly its segmental body composition analysis feature, which is said to identify muscle imbalances and excess fat in the arms, legs, and torso. A more tangible benefit is that this scale is battery-powered, while most models run on AAA batteries.
On the other hand, if you prefer a simpler alternative, their Body Smart scale is only $89.95.
