Best smart scales in 2020

Best smart scales

The best smart scales can be used to help you keep tabs on your weight, whether you're looking to achieve fitness goals, maintain your current form or get insight on your body. When you’re trying to stay on track, you might even find yourself stepping on your scale every day.

Like most of the devices in our lives, the boring bathroom scale has received a digital facelift and can now connect to your smartphone and show you a collection of metrics, like your body mass index (BMI), body composition and your heart rate. While you're shopping for any of the best smart home devices, why not upgrade to one of the best smart scales?

Several of the best smart scales also pair with your wellness program of choice, whether you use Apple Health, Google Fit or any of the best fitness apps. This way you can see how your workout and diet routines have affected your weight. Plus, like with any of the best fitness trackers for your wrist, you can check on your heart rate in seconds when you step on some of these smart scales. 

See all of the best smart scales below.

What are the best smart scales?

After testing several of the best smart scales ranging in price from $20 to $180, our top pick is the Withings Body Plus. At $79, The Withings Body Plus is not the least nor the most expensive smart scale, and it measures far more than just your weight. The Wi-Fi based device syncs with the company’s proprietary app, which is an intuitive tool for seeing a complete picture of your body composition. Better yet, Withings Body Plus pairs with all of the top fitness apps, including Weight Watchers and MyFitnessPal. 

Withings also makes a $59 version of its smart scale called the Withings Body. It doesn’t track as many metrics as the Body Plus and can’t read your heart rate, but most people will find it suits their needs. It also benefits from Withings’s Health Mate app, meaning you can see your body’s changes over time. The Withings Body is a great choice if you're looking for a low cost smart scale that syncs with your MyFitnessPal goals. 

Of all the best smart scales, though, the Wyze Scale is what we’d recommend for people on a budget or who are trying out a smart scale for the first time. We're pretty impressed by what this $20 gadget offers.

As one of the best home gym equipment devices that won’t break the bank, the Wyze Scale supports up to 8 unique users, offers 12 different health metrics and even displays some of those metrics directly on the scale’s display. The Wyze Scale’s main caveat is that it’s Bluetooth enabled, meaning your data will only update when your smartphone is within range.

Here are the best smart scales you can buy today

Best smart scales: Withings (Nokia) Body Plus

1. Withings (Nokia) Body+

The best smart scale overall

Connectivity: Bluetooth, Wi-Fi | Size: 12.8 x 12.8 inches | Android/iOS: Yes/Yes | Max Users: 8 | Stats: Weight, BMI, heart rate, weather | Max Weight: 396 pounds | MyFitnessPal Compatible: Yes | Batteries: 4 AAA

Well-designed app
Useful stats on-display
Pregnancy mode
Stylish design
Small display

Overall, the Withings Body Plus is the best smart scale. It sports an attractive design, gathers more information than any other scale and presents the data in an easy-to-understand app. Each and every weigh-in appears in the companion Health Mate app automatically, via Wi-Fi or Bluetooth sync. And with your measurement history available at any time, you can see what parts of your routine are bringing you your desired results. The Withings Body Plus also has a useful pregnancy mode, which can give you readings without raising safety concerns when you're expecting.

For an upgrade, the $150 Withings Body Cardio offers heart health features, including a Pulse Wave Velocity measurement that is only available to users in the European Union. That data can be an indicator of hypertension, but the scale itself doesn't diagnose medical conditions.

2. Wyze Scale

The best budget smart scale

Connectivity: Bluetooth | Size: 12 x 12 | Android/iOS: Yes/Yes | Max Users: 8 | Stats: 12, incl. weight, BMI, heart rate | Max Weight: 400 pounds | MyFitnessPal Compatible: No | Batteries: 4 AAA

Extremely affordable
Supports up to eight profiles
Apple Health and Google Fit integration
‘Safe mode’ for pregnant users
No Wi-Fi connectivity

Of all the best smart scales, the Wyze Scale is our top budget pick because it's loaded with features and costs a mere $20. The Wyze Scale supports a whopping 12 health metrics, including weight, body mass index (BMI), heart rate, muscle mass, body water percentage, lean body mass, bone mass, visceral fat and more. It looks as good as the Withings Body Plus, and while its display and app is a bit more basic, it includes Apple Health and Google Fit integrations that can help you see the full scope of your fitness journey.

We wish the Wyze Scale had Wi-Fi connectivity so we didn't need to keep our phone nearby for data syncing, but that’s a minor qualm. This is a great pick for your first smart scale purchase, and will cost you less than most other fitness equipment on the market.

Best smart scales: Withings (Nokia) Body

3. Withings (Nokia) Body

The best budget scale runner-up

Connectivity: Bluetooth, Wi-Fi | Size: 12.8 x 12.8 inches | Android/iOS: Yes/Yes | Max Users: 8 | Stats: Weight, BMI, weather | Max Weight: 396 pounds | MyFitnessPal Compatible: Yes | Batteries: 4 AAA

Easy set-up
Health Mate app lets you easily see trends
Accurate weight and weather data
Pregnancy mode
Display could be larger

If you don't need a scale with quite as many features, Withings' $59 Wi-Fi scale, Withings Body, delivers the basics in a stylish package. The scale measures your weight, of course, and does so accurately.  We compared it to the $150 Body Cardio and a dumb (er, not Internet-connected) $20 digital scale, and the scale was within 0.2 pounds of both.

The Body, which comes in black or white, has a 2.4 x 1.6-inch display that flashes your weight, weight trend (up or down), BMI and the weather forecast. That's useful if you're weighing in at the beginning of the day before you head outside. The screen isn't the biggest, but it's easy to read and the numbers are big and bright.

The scale syncs with the Health Mate smartphone app, which is where its Wi-Fi connection comes in handy. There you can view your data as a dashboard and see how your weight and BMI fluctuate over time. You can also set goals and pair the scale with apps such as MyFitnessPal. And like Withings's higher-priced scales, the Body offers a pregnancy mode.

The Body doesn't measure your heart rate or your home's air quality, but those are bonus features you can do without to save some money. Plus, this scale works with both iOS and Android devices.
  

Best smart scales: Eufy BodySense

4. Eufy BodySense

A reliable and affordable smart scale

Connectivity: Bluetooth | Size: 12 x 12 inches | Android/iOS: Yes/Yes | Max Users: 20 | Stats: Weight, BMI, BMR, body fat percentage | Max Weight: 397 pounds | MyFitnessPal Compatible: No | Batteries: 4 AAA

Sleek, stylish design
Excellent display
Fast results
No pregnancy mode
No Wi-Fi connectivity

Eufy's Bluetooth scale, which pairs effortlessly with the EufyLife app for iOS and Android, displays your weight almost instantly on-screen. As one of the best smart scales, it nailed the weigh-in. The BodySense scale then syncs that number, along with a host of other metrics, to the app. Those other data points include BMI, what percentage of your body fat is made of water, and how much of your weight is muscle mass, bone mass and body fat mass.

Some Amazon reviewers have noted that the measurements appear to be based on percentages rather than actual fluctuations. But the scale highlights trends and lets you know whether numbers are considered normal for your age, height and weight.

There are a few drawbacks, though, when you compare the Eufy BodySense to the Withings Body. Eufy's scale lacks a pregnancy mode, which makes it a no-go for women who are pregnant or who are planning to become pregnant. The scale also doesn't give you a weather report during your morning weigh-in the way Nokia's does.

But it does support up to 20 different users and offers detailed analysis for a $30 scale, which makes Eufy's BodySense an excellent budget pick.
  

Best smart scales: Fitbit Aria 2

5. Fitbit Aria 2

The best smart scale for Fitbit users

Connectivity: Bluetooth, Wi-Fi | Size: 12.3 x 12.3 inches | Android/iOS: Yes/Yes | Max Users: 8 | Stats: Weight, BMI, body fat percentage | Max Weight: 400 pounds | MyFitnessPal Compatible: No | Batteries: 3 AA

Syncs with Fitbit trackers
Works with third-party apps
Small display
Takes too long to display weight

The Fitbit Aria 2 is a refreshed version of the original Aria, though it doesn't look much different with its all-glass body and backlit LCD display. The next-generation smart scale is more accurate than the first Aria, Fitbit says, and that proved true in our testing.

The Aria 2 measures the weight, body fat percentage and BMI of up to eight users, which it then automatically syncs to the Fitbit app. If you use any of the best Fitbit models, the app's dashboard syncs information about your weigh-ins with your daily workouts and the food intake you manually input for a true overview of your body on any given day.

The scale takes several seconds to display your weight, which is annoying. It also lacks support for pregnant women. But if you're deeply embedded in the Fitbit ecosystem, the Aria 2 is worth a look.
  

Best smart scales: QardioBase 2

6. QardioBase 2

Most stylish smart scale

Connectivity: Bluetooth, Wi-Fi | Size: 13.4 inches in diameter | Android/iOS: Yes/Yes | Max Users: 8 | Stats: Weight, BMI, body fat percentage, muscle, bone, water composition | Max Weight: 396 pounds | MyFitnessPal Compatible: Yes | Batteries: Rechargeable (microUSB)

Stylish design
Unique feedback modes
Collects a slew of metrics
Takes several seconds to display weight

The best smart scale for those who care about design, the new QardioBase is about an inch larger in diameter than its predecessor, which makes it more stable. This version is also rechargeable and lasts up to a year on a charge instead of needing all those batteries.

The QardioBase 2 is one of the most stylish scales around, if you care about what you're looking at when you weigh yourself. A scale takes up a not-small amount of space in your bathroom, so at least this one looks good.

Qardio is now integrated with third-party apps such as Apple Health and MyFitnessPal, a long-awaited move that we docked points from this scale initially.

However, one drawback to QardioBase 2 compared with other smart scales is the time it takes to display your weight on the display, which is located in the center of the device (where you stand). In testing, it took about 12 seconds for a number to pop up, rather than the near-instantaneous readings we get from other smart scales.

QardioBase 2 has a couple of unique features, such as a smart-feedback mode that shows you smiley faces instead of numbers and a pregnancy mode you can customize according to your due date. You can choose a mode at setup or adjust it later in the Qardio app for iOS or Android. You can use the app to set goals and see charts of your progress over time, as is standard for a smart scale.
  

Best smart scales: RolliBot Rollifit F8

7. RolliBot Rollifit F8

An inexpensive cross-platform scale

Connectivity: Bluetooth | Size: 11.9 x 11.9 | Android/iOS: Yes/Yes | Max Users: Unlimited | Stats: Eight metrics, including weight, BMI, BMR, bone mass, visceral fat | Max Weight: 400 pounds | MyFitnessPal Compatible: No | Batteries: 3 AAA

Google Fit, Apple Health and Fitbit compatibility
Beautiful display
No Wi-Fi connectivity
Bluetooth issues

RolliBot is an unfamiliar name to most buyers, but the company's attractive Bluetooth $30 Rollifit F8 scale is attractively priced. Other scales are worth the extra money, but the F8 is a decent option that works with the biggest health apps: Apple Health for iPhones, Google Fit on Android and Fitbit’s cross-platform app.

The Rollifit F8 has a slightly smaller footprint than most, coming in under 12 inches, and both black and white models of the scale appear to lack a display until you step on the tempered glass. Four bioimpedance sensors take measurements in the background that are synced to the Rollifit app for iOS or Android after you weigh in. The display shows just one metric: your weight.

The additional stats, such as visceral fat and bone mass, are interesting to see in the app's dashboard, although I'm not convinced they're accurate.

Our biggest issue with the Rollifit F8 is its Bluetooth-only connectivity. It took forever to pair the scale with our phone, despite the scale showing up as connected in our Bluetooth settings. The app disconnects itself from the scale when not in use, which makes sense to save power, but then it takes several attempts to reconnect the two.

The good news: You can use the scale as a basic digital scale, no app required. But for deeper metrics and easier use, the Withings Body+ is still our top pick.

How to choose the best smart scale for you

A smart scale isn’t a device you want to replace often, so you want it to be reliable, well-rounded and fill all your fitness tracking needs. In other words, don’t let price be your ultimate decision-maker. It’s worth it to stretch your budget for one of the best smart scales that will last you at least a few years, and supports the exact data you’re interested in following. Review all the metrics a given smart scale offers before buying.

That said, if you’re in temporary living quarters or are working towards a short term fitness goal, a budget smart scale, like the Wyze Scale, is an excellent choice. It won’t last a lifetime but will satisfy your immediate needs. 

Another thing to pay attention to is whether a smart scale has some kind of ‘safe mode’ for people with pacemakers or people who are pregnant. Safe mode, or ‘weigh only’ mode, disables bioelectric impedance analysis (BIA), which uses a weak electric current to determine body fat percentage and could pose a safety threat to certain users.

How we test the best smart scales

For our review of the best smart scales, we take a number of factors into consideration. First, we check that the scale offers an accurate reading using a dumber digital scale, the highly rated EatSmart digital bathroom scale. If the readings are within a fraction of a pound of each other, we can recommend them. The readings shouldn't take more than few seconds, either.

Aside from price, we also explore the variety of metrics a scale offers, how many unique users the scale supports, the scale’s connectivity options and the user-friendliness of the scale’s companion app. We like to see whether the app provides background information on your body’s statistics, too. Plus compatibility with third-party health programs plays a role in our testing.

The last thing anyone needs is more anxiety, so we look for the best smart scales to make stepping on the platform less intimidating. A smart scale’s metrics should reveal to you that your body is more than your weight.

    Thanks for your review. I was researching scales and after going from a regular cheap digital weight scale for $17.85, to wanting one that could sync with myfitness.com and realizing that they are not just scales anymore, I chose the Nokia Body+ Body Composition based on your review. I had rewards built up with a major retailer and was able to get this basically for free. I just had to pay $20.00 to extend the warranty for 2 more years.

    The Nokia Body+ does not monitor air quality. The Smart Body Analyzer WS-50 is the scale that does this.

    The Nokia scales (formally Withings) have lots of software problems. They stop syncing all the time and require you to resync every few days. The Fitbit scale doesn't sync with health kit because they are a backward company and only they want to keep all your data. I would avoid both of these.

    As SGD5026 says. I'm finding nothing that sates Nokia body + monitors air quality. Nor does it measure heart rate apparently. For the heart rate you'd need the Nokia body cardio that sells for $180.

    Your Amazon link to the Nokia Body Plus is wrong.

    I have a withings scale (that I love) but I'm tied to the Garmin ecosystem because I have a forerunner watch (that I also love).

    So I built an app called Smart Scale Sync that syncs weight from Withings to Garmin/Strava/TrainerRoad. I'll be adding support for fitbit scales soon.
