Planning a Fitness Comeback In 2021? Grab One of These Smart Scales

Photos of various smart scales with men and women using them.

Whether you’re still feeling post-holiday-feast guilt or are just determined to make 2021 better than its predecessor (aren’t we all?), getting in better shape is most likely on your list of goals. One way to keep yourself motivated and your habits consistent is with a smart scale.

Smart scales can provide significant insight into your health and help you keep track of your progress. These smart scales combine three useful things into one. First, like you’d expect a scale to do, they help you weigh yourself. Second, they measure the composition of your body using a technology called “bioelectric impedance” to send a low-level electrical current through the lower half of your body to determine its composition measurements. (Don’t worry—you won’t feel a thing!)

While scales that can do those first two things have been on the market for some time, what makes smart scales, well, smart is that they take all that handy information and shoot it over to your smartphone via Bluetooth. What good is getting all that body data every morning if you have to manually write it down, after all?

Once the data—typically your body mass index (BMI), body fat percentage, muscle mass, and water weight—is on your device then it’s simple to graph changes over time, share it with your health apps, or otherwise get more use out of it than simply staring at it on the little display each time you weigh in.

If you’re ready to invest, below are some of our favorite smart scales. We’ve also divided them by category to help you find the model that’ll work best for you.

Best Overall Features: Withings Body+

The Withings Body+ smart scale and its companion app on a phone.

This smart scale has been a best-seller since it first came out. While it’s not the cheapest option out there, the Withings Body Plus scale offers excellent features and a high level of accuracy. With its patented Position Control technology, the scale guides you through every weigh-in and syncs all the information with its companion app.

The app also pairs with over 100 health, food, and fitness apps, like MyFitnessPal, WeightWatchers, and Runkeeper. The system supports up to eight people, and everyone can set their weight goals and daily calorie budgets. It also features a “Pregnancy Tracker” and “Baby Mode” for expectant mothers and infants.

Recently, the company released an upgraded (and more expensive) model called Withings Body Cardio. On top of providing you with the basic body composition information, it also tracks your standing heart rate, which is an important indicator of heart health.
