Best Smart Home Scales That Get to Know You

If you’re embarking on a weight loss journey in 2021, you may want to invest in a smart scale. It used to be that stepping on a bathroom scale was for one reason only: to check your weight. But these days smart scales can do a whole lot more than just that. They can measure body fat percentage, muscle mass, and even your bone mass. They can also tell you your basal metabolic rate (BMR) so you know how many calories you’re burning. Here we’ll share our top picks for the best smart home scales that get to know you.

How Do Smart Home Scales Work?

Smart scales use Bluetooth or wifi to send your metrics to smartphone app where you can view and track them. Depending on the scale, your info can also be synced with Apple Health or Google Fit. Paired with fitness trackers like the Fitbit or Apple Watch, a smart scale is a powerful tool to track your fitness progress.

Smart scales measure your body composition by using bioelectric impedance analysis (BIA). This sends a weak electrical current through your body. The electrical current faces resistance moving through body fat but moves easier through muscle. While the body fat reading accuracy of any scale has its limitations, it’s helpful for tracking progress.

The Best Smart Home Scales That Get to Know You

Eufy BodySense Smart Scale

Clocking in at an extremely reasonable $45, the Eufy BodySense Smart Scale gets our vote for best overall smart scale pick. This scale measures weight and your percentages of body fat, BMI, water, muscle, bone, and basal metabolic rate (BMR), as well as visceral fat. (Visceral fat is excess fat that forms around the center of the body and is linked to numerous health problems.)

The Eufy BodySense connects to the Eufy Life app on your smartphone via Bluetooth. Inside the app, you can track even more metrics:  lean body mass, body fat mass, muscle mass, and bone mass. This smart scale integrates with all the big third-party health apps, including Google Fit, Apple Health, and Fitbit. The scale can measure weights up to 396 pounds.

Something to be aware of is that like most other smart scales, Eufy smart scales determine your body composition by sending a weak electrical current through your feet. This is not recommended for people with pacemakers or pregnant women. This scale doesn’t have a way to turn this feature off, so if you fall into either of those categories, check out the Wyze Scale we recommend in this article instead. One other minor area of concern with this scale is a lack of data privacy. This smart scale supports up to 16 different users, however note that because all data is synced from one account, all users will be able to view everyone’s data. This likely won’t be a problem for most smart scale users, but it should be noted if you live with roommates.

ProsCons
Measures 12 different metricsLacks pregnancy mode
Connects to Apple Health, Google Fit & FitbitNo data privacy
Up to 16 different usersNo wifi connectivity

Fitbit Aria Air

The Fitbit Aria Air may seem like an obvious choice for dedicated Fitbit users. It syncs with your Fitbit app, meaning it works in tandem with your Fitbit fitness tracker to help you keep a close eye on your weight. However, that’s about the only thing it does. If you’re looking for more sophisticated metrics like body fat percentage, muscle mass, or bone mass, you’ll want to look at a different smart scale. The Fitbit Aria Air is fairly expensive considering its limited functionality, with a price around $50. However, if you’re just looking for a basic bathroom scale to track your weight, this is a fine buy.

Note that this scale is not compatible with Apple Health or Google Fit. In that sense, it’s really best only for committed Fitbit fans who want to keep a close eye on their weight loss.

ProsCons
Syncs with Fitbit app
Only measures body weight
Easy to read
Not compatible with Apple Health or Google Fit
Accurate weight readingsExpensive for limited functionality

Garmin Index S2

For anyone that already wears a Garmin fitness tracker, pairing it with the Garmin Index S2 mart scale makes for a dynamic duo. This smart scale measures weight as well as BMI, body fat, body water, bone mass, and muscle mass. The Index S2 also has a convenient weight-tracking feature right on its readout screen that tracks weight changes over the last 30 days. This is extremely helpful if you’re on a weight loss journey or simply looking to maintain a consistent weight.

The Garmin Index S2 connects via wifi or Bluetooth to the Garmin Connect app on your smartphone (Android and iOS). Paired with a fitness tracker, it can give a comprehensive overview of your overall health, including tracking metrics over time like your weight, heart rate and activity level. While this smart scale doesn’t have a rechargeable battery, its expected battery life on 4 AA batteries is up to 9 months. It’s fairly expensive at around $135, but if you use a Garmin fitness tracker, this is a great buy to track your health and fitness.

ProsCons
Up to 16 different user profilesExpensive
Sleek modern designLacks pregnancy mode

Withings Body Cardio

If you’re willing to spend a little more, Withings make some of the best smart scales available right now. Its Withing Body Cardio model is loaded with unique features, but at $149 you’ll definitely pay for them. The Pulse Wave Velocity feature estimates arterial health, a feature we haven’t seen in other smart scales just yet. The scale also measures your heart rate through your feet, although this definitely isn’t as accurate as other heart rate measurement methods. The app is equipped with a Pregnancy Tracker that helps expecting women track healthy weight gain. There’s also “Baby Mode” to track the newest member of the family.

The Withings Body Cardio is both Bluetooth and wifi enabled to connect to the Withings Health Mate app for iOS and Android. It can sync with your Apple Watch as well as more than 100 different health apps including Apple Health, Fitbit, and Google Fit. Additionally, the Withings smart scale also displays the current weather and temperature. It may seem like an odd feature for a bathroom scale, but it certainly helps with getting dressed in the morning.

ProsCons
Rechargeable batteryHigh price
Bluetooth & wifi enabledHeart readings aren't the most accurate
Measures weight accurately

Wyze Scale

If you’re on a budget and want bang for your buck, the Wyze Scale is your best bet. Priced at a paltry $19.99, it’s a fantastic smart home scale for the price. It even has some features, like pregnancy mode, that its far more expensive competitors lack. The Wyze Scale measures weight, BMI, BMR, muscle mass, body water percentage, lean body mass, bone mass, visceral fat, heart rate and protein. It also has a sleek modern design in shiny black that will look great in your bathroom.

Note that the Wyze Scale only displays weight and body fat percentage. To view your other metrics, you’ll have to use the Wyze smartphone app. The app tracks your metrics over time, meaning you can view how your weight, body fat percentage, etc. have changed over the past month or year. The Wyze scale offers app syncing and auto-recognition for as many as eight different people, making it perfect if you have a big family.

One great feature that the Wyze scale has is its Only Measure Weight mode. The minor electric current that scales send through for body for BIA measurement can have an effect on pacemakers. Only Measure Weight mode disables the electric current and only measures weight. Pregnant women may also want to use this mode to alleviate any concerns.

ProsCons
Lowest priced modelLimited app support
Auto-recognition for up toa 8 peopleNo wifi connectivity
Only Measure Weight mode (AKA pregnancy mode)Scale only shows weight & body fat

Features to Look for in the Best Smart Home Scales

Support for Multiple Users

If you have a large family who will all be using the scale, be sure to get a smart scale that supports multiple user profiles. Most smart scales can support 8 or even up to as many as 16 different users. This means that the smart scale will recognize each person when they step on their scale, and keep a memory of each person’s individual metrics so they can be tracked over time.

Pregnancy Mode

If you’re expecting (or expect to be expecting), look for a smart scale with pregnancy mode, as well as one where the BIA measurement can be turned off. Pregnancy mode means the scale keeps in mind normal weight gain during pregnancy and helps you track progress over the nine-month period. Most smart scales use BIA, or a weak electric current, sent through your feet to measure body composition. Some consider this electric current dangerous for pregnant women and recommend avoiding it. Note that the small electric current sent through your body during BIA measurement can also affect pacemakers. If you wear one, you’ll want to look for the same ability to turn BIA measurement off.

Third-Party App Connectivity

When shopping for a smart scale, look for one that specifically works with whatever health or fitness apps you may already be using. For instance, only some smart scales can connect to Apple Health or Google Fit. Others work best with the fitness trackers from their manufacturers, such as with Garmin and Fitbit. By choosing a smart scale that integrates with the app you’re already using, you’ll be able to get a simple comprehensive look at your overall fitness.
