The 11 Best Smart Scales of 2022

Verywell Fit / Jessica Juliao

Smart scales can help measure and track body weight as well as other metrics, like body mass index (BMI), body fat percentage, muscle mass, and more. While standard scales typically only display weight from their screen, smart scales often wirelessly connect to your smartphone via compatible apps, record data from multiple users over time, and even help track health goals.

Tested & Approved

Our top pick is the eufy Smart Scale P2 because it can monitor unlimited users and measure and track 16 different body metrics. The RENPHO Body Fat Scale measures similar metrics at a lower price point.

A significant advantage of using a smart scale is the ability to create a digital, long-term health history by transferring and storing data in a user profile. Compared to the passé “dial” scale, Dr. Katie Rosenfeld, Weight Loss Clinic Physician with DuPage Medical Group Obesity Medicine, says smart scales tend to be much more accurate for routine weight management.

We tested 20 top-rated smart scales in The Verywell Testing Lab to find the best on the market. Five testers evaluated each scale for setup, accuracy, precision, and readability. They scored each product on a scale from 1 (would not recommend) to 5 (highly recommend) based on these attributes, as well as data storage, ease of use, and overall value. 

Based on our testing insights, here are the best smart scales on the market.

Who else recommends it? Tech Radar also picked the eufy Smart Scale P2 Pro.

What do buyers say? 92% of 5,300+ Amazon reviewers rated it 4 stars or above.

After receiving a perfect score for five out of six of the key attributes we tested for, the eufy Smart Scale P2 was an obvious top pick. Our tester loved this smart scale and gave it high marks for overall value. We like it for its easy setup, intuitive app, sleek design, and overall positive experience.  

The eufy’s P2 Smart Scale earned a perfect score of 5 out of 5 for setup, precision, data storage, ease of use, and overall value. Our tester found that the scale was easy to set up, seamlessly paired with a smartphone, and quickly connected to the corresponding app. The scale can also link to Apple Health and Fitbit. 

When our tester weighed herself multiple times (with and without a control weight), the reading was consistent each time. It was also simple to add and switch between users with just a few quick taps. 

What’s more, the compatible app has two different modes for weighing pets and babies, and it allows you to make separate profiles for each. On the app, you can track 16 different metrics—including BMI, heart rate, muscle mass, bone mass, and water—set specific goals, and export your reports for easy viewing and tracking. 

Readability is the only attribute this scale didn’t receive a perfect score for, only earning a 4.5 out of 5 for the attribute. Our tester said that the display was very easy to read and that changing between units was simple. But additional measurements (like heart rate, visual representation of weight trends, and other metrics) are only visible on the app and are not displayed on the actual scale, which is why it lost points in the readability department.

Weight Capacity: 397 pounds | Connectivity: Wi-Fi and Bluetooth | Metrics: Weight, body fat, BMI, muscle mass, bone mass, water, protein, BMR, visceral fat, body fat mass, lean body mass, body age, body type, skeletal muscle mass, subcutaneous fat | Users: Unlimited

What Our Testers Say

“This scale is a bargain! I was shocked by how low the price was—especially with all the features and functionality it offers. I expected it to cost well over $100. Get this if you're looking for a smart scale!”—Sarah Felbin, associate commerce editor, Verywell Fit product tester

Pros

  • Easy to read 

Cons
  • Readings may be slightly inconsistent

Although this scale was the third least expensive among the 20 we tested, it scored among the top six—scoring higher than many of the more expensive options. The RENPHO Smart Scale is a great budget-friendly option. Our tester found it to be easy to set up, read, and use—giving it a perfect score of 5 out of 5 in those three areas. 

When testing for precision, this scale performed considerably well. Our tester noted a 1-pound difference in her weight from a standard scale to the RENPHO Smart Scale. However, her weight remained consistent on the smart scale through multiple weigh-ins. 

Utilizing bioelectrical impedance analysis (BIA), the scale calculates 13 body composition metrics, including weight, body fat percentage, basal metabolism, and more. Our tester loved that the scale displays a visual representation of your body metric trends each time you weigh in. Its user-friendly app also enables users to save and track progress, as well as sync with many popular third-party fitness apps

What Our Testers Say

Pros
  • Very accurate

  • On sale often

  • Can create baby profiles

Cons
  • Inconsistencies between scale and app reading

We still recommend RENPHO as our top budget pick, but this FITINDEX Smart Scale comes in a close second for its great price tag and consistent accuracy. At each of our testers' weigh-ins (on both carpeted and non-carpeted flooring), the scale displayed the same exact weight. It’s also easy to set up and pairs quickly with the compatible app. 

The app tracks 13 metrics, and you can set specific weight and body fat goals. However, our tester did find inconsistencies between the weight that the scale displayed and what was shown on the app—noting a 10-pound difference, which threw off the rest of the metrics on the app. 

Overall, the app is not super user-friendly, but the scale is a great scale. We found that this smart scale offers a lot of features for a low price point, but it lacks functionality in some areas. If you’re looking for a basic scale for weigh-ins that is super budget-friendly, this is it.

Weight Capacity: 396 pounds | Connectivity: Bluetooth | Metrics: Weight, BMI, body fat percentage, water percentage, skeletal muscle, fat-free body weight, subcutaneous fat, visceral fat, muscle mass, bone mass, protein, basal metabolism, and body age | Users: Unlimited

What Our Testers Say

“I would recommend this scale if you're looking for a basic scale. As a basic scale, this one has a nice design, is easy to read, and is simple to calibrate. But if you're relying on an app to help you track metrics, then I would look elsewhere.” —Sarah Felbin, associate commerce editor, Verywell Fit product tester

For its high accuracy, affordable price, and super-sleek look, this smart scale is our top pick for design. It’s made of tempered glass and comes in white, giving it an elegant look that will blend well with most bathrooms. 

Our tester gave this Arboleaf Smart Scale a perfect score for five out of six of the key attributes we tested for—specifically noting its excellent precision and accuracy. After our tester initially weighed herself and stepped back on the scale while holding a control weight, the scale recognized the immediate increase in weight and prompted her to confirm that it was still her on the scale. 

The smart scale seamlessly connected to our device, and the data was easily transferred over to the app (the scale also is compatible with third-party apps). Our tester loved the layout of the weight breakdown and other health information on the app. She liked that, along with numerical values for metrics, the app also offered written explanations for what each metric stands for.

Cons
  • Can only hold up to eight users

  • Only measures weight and BMI

This smart scale displays useful data (like BMI) right from the scale’s screen instead of having to read it on the app, making it easy and convenient to use. It also pairs with the Apple Health App and over 100 other top health apps, allowing you to track your daily steps. Pregnancy, baby, and athlete modes are also available, making this a truly versatile scale.

The setup took several minutes (only earning 4 out of 5 stars), but our testers found it to be worth the wait for the great features this scale offers. The scale is lined with carpeted feet so that readings are precise on all surfaces. Our tester thought the scale was easy to read—displaying your weight, BMI, step count, weight trends, and even the weather right from the scale’s screen. 

As for the compatible Health Mate App, our tester found it to be extremely helpful and fun to use. You can easily track workouts and meals and connect to Apple Health to retrieve other handy health data. The user-friendly app allows you to add users easily and displays highly useful information to help you meet your goals and make lifestyle choices.

While our tester preferred the P2 version of eufy’s Smart Scale, this P1 version is more affordable and still offers the same compatible app that we loved. As previously mentioned, the user-friendly eufy app allows you to track 16 different metrics, set specific goals, and export your statistics for easy viewing. It also offers two different modes for babies and pets and makes it very easy to switch between users.  

This scale received a perfect score of 5 out of 5 for setup, precision, and data storage for its intuitive functionality and standout accuracy. Our tester found the scale’s screen easy to read but noted that the display numbers disappeared relatively quickly after she stepped on the scale for a reading. 

We found this scale to be fairly priced for its easy-to-use features and amazing app. We recommend it as the more affordable but slightly less efficient option of the two eufy smart scales we tested.

Pros
  • Very accurate

  • Expensive

The Omron Body Composition Monitor and Scale provides full-body sensing to help users gain further insights into their unique body composition. For the highest degree of accuracy, body fat percentage is calculated using a retractable handheld sensor that takes measurements from both the hands and feet. This smart scale measures weight, body fat percentage, BMI, skeletal muscle, resting metabolism, visceral fat, and body age. 

The scale displays your metrics directly on the screen (which our tester found was easy to read) and doesn’t require an app—making it a more low-maintenance option. While the scale is slightly bulky and harder to set up than others we tested, it does a really great job of providing important and accurate body metrics. Our tester gave this scale a perfect score of 5 out of 5 for precision, as it read a consistent weight regardless of our controls. 

Because there is no app, it may be a bit more difficult to track your progress. But all of your metrics are stored directly on the scale and can be accessed on-screen with just the touch of a button.

This smart scale tracks weight, BMI, standing heart rate, and four other key body composition metrics that you can view on its compatible Health Mate App. This helps users track progress over time, creating a digital health history that can be easily shared with family members and healthcare providers. 

Withings reports that users who set a weight goal on an app lose twice as much weight as those who don’t. This scale also syncs to popular apps, including MyFitness Pal, that allow you to track nutrition. Our tester loved this feature because she was able to monitor her food intake while tracking other health metrics. 

Withings Body Cardio Scale also comes equipped with detailed instructions on how to set up the scale and use it for the most accurate measurements possible. However, our tester noted that, while the scale provided extremely precise measurements, the app took a lot of time to configure—earning it a 3.5 out of 5 for setup.

How We Rated The Best Smart Scales

4.8 to 5 stars: These are the best smart scales we tested. We recommend them without reservation.

4.5 to 4.7 stars: These smart scales are excellent—they might have minor flaws, but we still recommend them.

4.0 to 4.5 stars: We think these are great smart scales, but others are better.

3.5 to 3.9 stars: These smart scales are just average.

3.4 and below: We don't recommend smart scales with this rating; you won't find any on our list.

How We Tested The Smart Scales 

To generate a list of our top 10 smart scales, five of our expert product testers evaluated 20 smart scales in The Verywell Testing Lab to see how they performed in key areas—including setup, accuracy, precision, readability, data storage, ease of use, and overall value. 

Setup 

The first attribute we tested for was setup. Testers unboxed each smart scale, downloaded the corresponding app, and paired the scales with their smartphones. They noted how easy the scale was to set up, how intuitive the app was to navigate, and how efficiently the scale paired with their devices. Testers also checked each scale's compatibility with common apps like Google Fit, Apple Health, and more. 

We paid special attention to the seamlessness of the entire setup process—giving smart scales a high rating for this attribute if they involved minimal setup, clear instructions, quick pairing, compatibility with common apps, and the presence of all necessary equipment to get started.

Accuracy 

Accuracy is essential when choosing the right scale. To determine the accuracy of each smart scale, we used a control item—for this test, a bowling ball. Testers used each scale to weigh the bowling ball on a flat surface and then on a carpeted surface, noting any changes in the ball’s weight. Regardless of the surface, the scale should have read the same weight for the bowling ball both times. This simple test helped us to identify the accuracy of each scale. 

Precision 

Next up was our precision test. Our testers weighed themselves three times (first on a standard scale and then on the smart scale) to check for consistency. Then, they held a 5-pound dumbbell and weighed themselves three more times—ensuring that their first number had increased by 5 pounds, as expected. Testers noted whether or not the smart scales read the same as the analog scale and if their weight remained consistent throughout the test, varying no more than two decimal points. 

Smart Scales Test

Verywell Fit / Tamara Staples

Readability 

For any scale to be worth it, you need to be able to clearly read the data that it’s displaying. For our readability test, testers stood on each smart scale to weigh themselves and noted how easy it was to read and interpret the displayed weight. We took special note of how seamless it was to switch between users, if the display was well-lit and easy to read from a distance, and if testers could effortlessly decipher the information the scale provided. 

Smart scales that received a high score for this attribute could switch from different weight units quickly, had a bright display screen with large enough numbers, and offered data readings in pounds, kilograms, and stones. 

Data Storage 

Choosing a smart scale over a standard scale is great if you’re trying to track your fitness goals and improve your lifestyle—making data storage hugely important. Your scale needs to have the capacity to record and store your metrics (like BMI, total body water, muscle mass, and more). 

During our Lab test, we checked each smart scale for its data storage and user abilities. Our testers gave high scores to scales that could be easily understood, provided more than 10 additional data points other than weight (like BMI, body fat percentage, etc.), could easily record data for at least 10 users, and had a compatible app to easily track metrics. 

Ease of Use 

Testers took note of ease of use throughout the smart scale testing process. Scales that did not require recalibration or additional instructions (like tapping your foot on the scale before use) received high scores for this attribute.

Value 

After rating the above attributes, testers were instructed to view the price of each smart scale and were asked, in terms of cost, if they thought the product was of good value. If testers believed the product worked very nicely and would, without reservation, pay the price of the product (or even consider paying more), it received a high score for value.

What to Look for in a Smart Scale

Fitness App Compatibility

Many smart scale models offer their own weight tracking app. For those who already use third-party fitness tracking apps and prefer to sync their existing health stats with weight tracking, look for a smart scale that interfaces with your preferred app.

The Withings Body Cardio Smart Scale, for example, is compatible with over 100 fitness tracking apps, such as MyFitnessPal, Noom, WW, Fitbit, RunKeeper, Apple Health, Google Fit, Strava, and many more.

Bluetooth and Wi-Fi Connectivity

Most smart scales are equipped with Bluetooth connectivity, allowing them to sync data with compatible tracking apps. The downside to Bluetooth scales is that you must have your smartphone within range to successfully log results. While some scales can save the results until the next sync, most low- to moderately-priced scales will not. 

Some smart scales are enabled with both Bluetooth and Wi-Fi connectivity, allowing you to interface with devices such as Alexa or Google Home. Wi-Fi-enabled smart scales, on the other hand, tend to be more reliable and easier to use as Bluetooth can sometimes be unpredictable. If the scale is within signal from a Wi-Fi router, it will sync. The one downside to a Wi-Fi-enabled scale is that they tend to be more expensive.

Metrics

Smart scales offer insight into our body composition, sharing much more than just weight. Features to consider when selecting a smart scale include body mass index (BMI), muscle mass, body fat percentage, bone mass, body water percentage, and more.

Weight Capacity

All scales have a maximum weight capacity. Before purchasing, ensure the scale can hold your weight.

Precision 

When using any type of scale, precision is essential. You want to ensure that each time you step on the scale, the displayed weight is accurate. In our tests, we used controls to check for precision for each of the smart scales we tested—we recommend you do the same when purchasing your smart scale.

Data Storage

One of the biggest perks of choosing a smart scale over a standard scale is its ability to record and track your metrics for later viewing. Smart scales allow you to keep track of your weight and other measurements, which can be helpful in your health and fitness journey. When purchasing a smart scale, you’ll want to check its data storage capacities. Look at how many users it can hold, how many measurements it will record, and how easy it is to keep track of your progress.

Smart Scales Test

Verywell Fit / Tamara Staples

Ease of Use

You want to find a smart scale that can be used effortlessly. The setup process should be straightforward, and the scale should be easily connected to its compatible apps. Readability should be a factor, too—making sure the displayed metrics are clear and easily read is important. Find a user-friendly smart scale that can be easily incorporated into your routine to help meet your lifestyle goals.

Frequently Asked Questions

  • Are smart scales accurate?

    While there are many factors that can affect the accuracy of a smart scale, they tend to be accurate for measuring weight and BMI. That said, there tends to be more variability when looking at the other measurements, such as body fat percentage and bone mass, according to Dr. Rosenfeld. 

    To garner the most accurate weight tracking data, she advises patients to step on the same exact scale each time to gauge the body’s weight fluctuations and trends. "Whenever you are using any body fat composition scale, it is best to avoid eating or drinking three hours prior to weighing yourself, so you can achieve the best possible results," she said.

  • How does a smart scale calculate body fat?

    Smart scales calculate your estimated body fat percentage using bioelectrical impedance. Sensors underneath the feet send an undetectable electric current from one foot through the body to the other foot.

    Vladimir Karpukhin, MSBCR (Medical Bariatric Surgery Clinical Reviewer) at Cedars-Sinai Marina del Rey Hospital, notes that electricity is conducted in the body by the water present in the muscle tissue. “In contrast to water, fat is a poor conductor of electricity.
