When choosing a bathroom scale, there are three main categories: analog—think old-school dial—digital, and smart scales, which automatically track and store data via Wi-Fi or Bluetooth.

Smart scales also offer additional metrics besides weight, including body mass index (BMI), body fat percentage, muscle mass, and more. This is great news, since body fat percentage is a much better predictor of the potential health risks that come with being overweight than weight alone.

One of the most significant advantages of using a smart scale is the ability to create a digital long-term health history. There is no need to manually record results, as the device wirelessly transfers data to your smartphone or user profile.

Here are the best smart scales on the market.
