These days, the humble bathroom scale can do much more than simply show your weight. Smart scales measure various body composition metrics like your body fat percentage, muscle mass, and water weight, and track your results in an app, serving as useful health and fitness companions. We’ve been testing smart scales for more than a decade, in our actual homes, using our own bodies. Our top pick, the Etekcity HR Smart Fitness Scale, is highly accurate and offers features generally reserved for more expensive models, including 14 tracked metrics, Wi-Fi connectivity for remote app syncing, and a rechargeable battery. That said, we also have five other top options on this list, all excellent in their own ways. Read on to find the perfect fit for your household.

Do Smart Scales Work With Fitness Trackers?

Unsurprisingly, the best smart bathroom scales are compatible with the best fitness trackers. When you pair a Wi-Fi- or Bluetooth-connected scale with a fitness tracker, you typically use just one app to see data from both devices. Add in a heart rate monitor or an at-home blood pressure cuff, and you have even more information on hand without the need for a spreadsheet or notepad.

Maybe you don't want to track your weight over time, but chances are your doctors and healthcare team do. Or maybe it's not you, but someone in your family who needs to keep an eye on their weight. Smart scales are smart enough to know the difference between a few different users and can track their weights separately and privately. Sharing data among family members and doctors is usually an option, too.

Smart bathroom scales automatically log your weight every time you step on them. Many of the best scales also measure body fat, while others track bone density and water percentage. Some can even read your heart rate through your feet.

What Do Smart Scales Track?

Although many people want to track their weight and the number of steps they take in a day to get a better sense of their health, some people are looking for more than that. Athletes and people who train regularly likely want a scale that has not only great features but also a companion app and tools that can help them on their journey.

We note in our reviews which fitness and health tracking apps each of these scales supports. Some work with apps that calculate your training intensity and chart your VO2 max, lactic acid threshold, and more. But if all this talk of VO2Max makes your head spin, you might prefer a smart scale with a simpler user experience.

Should You Get a Bluetooth or Wi-Fi Scale?

Smart scales typically use either Bluetooth or a combination of Bluetooth and Wi-Fi. Wi-Fi scales generally cost more because they require more components to work. They're also much more convenient.

To get your daily weigh-ins from a Bluetooth scale to the app for tracking, you need a Bluetooth device by your side. If you leave your companion smartphone, fitness tracker, or running watch in the other room, you're out of luck until it's within Bluetooth range. (Some scales can save a recorded weight until the next sync, but the cheaper ones do not.) A Wi-Fi-enabled scale doesn't have this problem. It syncs your data as long as it has a signal from your Wi-Fi router. In our testing experience, Wi-Fi syncing is also more reliable, whereas Bluetooth syncing fails from time to time.

How Does Pregnancy Mode Work on Smart Scales?

Women who are pregnant or who might become pregnant have unique needs when it comes to tracking their weight. Many pregnant women probably don't want BIA measurements (think body fat, bone density, and water percentage) because scales calculate those by sending mild electrical impulses through the feet. People who have a health device implant, such as a pacemaker, should also likely avoid smart scales that use BIA scanning.

Some but not all scales that support BIA measurements have the option to turn them off. If available, a pregnancy/weight-only mode typically disables the BIA function so the scale measures just your weight.

Fitness Underfoot

If you're looking for a new bathroom scale, we highly recommend buying one that's smart. There's real value for individuals, families, and healthcare providers to be able to track weight accurately and effortlessly over long periods. No matter your needs, you're sure to find a scale that suits them on this list.
