The Best Smart Scales

As our society grows more and more health-conscious, our home fitness tools need to keep up. Long gone are the days where one's health was judged based solely on body weight. From body mass index (or BMI) to body fat percentage and bone and muscle mass to metabolic age, there's a heap of other metrics that paint a picture of what's going on below the surface. That's why traditional bathroom scales just don't cut it anymore. Instead, smart scales — which sync and track your data via WiFi or Bluetooth — help you effortlessly create a long-term health profile that consists of more than just counting pounds. Below, we've weighed the different smart scale options available today to get you in the know in no time.

Frequently Asked Questions

Do I need to calibrate my smart scale?

Digital scales that are stationary and used daily really only need calibrating every few months. But if you’re moving your scale around a lot, or you’ve just replaced the batteries, then we recommend recalibrating it. While some smart scales automatically calibrate, others will need a bit of help every now and again, so check the instructions your particular scale came with.

How do I calibrate my scale?

Most of the time, you just need to step on the scale, let it read zero, and then step back on to get accurate results. In some cases, like if your scale comes with a “Cal/Mode” button, you’ll need to press the button and wait until the display reads “0” or “Cal.” Then place an object or series of objects that weigh a known amount on the middle of the scale until it reads out the correct number. After you get the reading, press the calibration button again to end the session, and you should be good to go.
