The best smart scales allow you to monitor your health and fitness goals, sync to your smart or fitness watch, all while tracking your overall body metrics. Traditional scales only tell you your weight, which is just a part of your total health picture.
Controlled by easy-to-install apps managed by your smartphone, smart scales are a sleek, wireless addition to your digital fitness lifestyle. As any fitness tracker or smart watch owner can attest, using technology to track your fitness goals can help motivate you to stay on track. Turning your daily walks and workouts into a game where you earn rewards and can beat your own stats makes exercise more fun. Smart scales use the same technology as fitness watches/trackers to measure electrical impulses that translate into body metrics like weight, body fat percentage, water weight, bone density, and muscle mass. Use a smart scale to watch in real time as your body transforms into a leaner, healthier machine.

How We Selected These Products
We arrived at our recommended products by carefully comparing popular models with excellent consumer ratings. Specifically, we considered the overall look and design of each scale, the scale’s available features, the app controls, the ease of using, the price, and customer comments. We compared smart scale models offered by Pohl Schmitt, Withings, Garmin, Qardio, Fitbit, and Xiaomi.
We were able to personally test the Garmin Index S2 Smart Scale as well as two models offered by Withings: the Body+ and the Body Cardio scales. We downloaded and installed the apps and compared metrics between the devices. We also considered the ease of set up and navigation within the app for the Garmin and Withings smart scales. Scales we weren’t able to test in person were compared based on customer comments evaluating ease of use, metric accuracy, and app control.
The Best Smart Scales: Reviews & Recommendations
Best Overall: Withings Body+ Digital WiFi Smart Scale
Why It Made The Cut: Withings Body+ scale came in as our top choice because of the ease of installation, use, and connection with other fitness apps. The app imports Apple Health or Google Fit, and is also compatible with over 100 other fitness apps.
- Weight Capacity: Up to 396 pounds
- Dimensions: 12.8 x 12.8 x 0.9 inches
- Weight: 4.4 pounds
- Automatic synchronization via WiFi
- Bluetooth Smart Ready
- Withings’ Health Mate app is easy to use
- Most useful for smartwatch fitness users
The Withings Body+ is a capable smart scale which offers up to 8 users metrics to track weight and body composition, with an athlete and non-athlete mode. Users can track their fitness goals noting the changes in their body fat, body water, muscle mass, and bone mass. Withings does manufacture and sell their own smartwatches, but the Withings Health Mate app easily syncs with other popular fitness tracking devices including those that use Apple Health and Google Fit. It’s compatible with iOS 14 and higher, and Android 8.0 and higher.
Withings sells three models of smart scales depending on how many features and metrics you’re interested in gathering. Withings Body provides weight and BMI metrics only, but the Body Plus+, which is the model we tested and recommend, offers additional metrics which offer a more complete analysis of your health, including water weight, muscle mass, fat mass, and bone mass which are useful when training. We also tested the Body Cardio scale which is Withings most advanced and most expensive smart scale. The additional metrics of that model are primarily for gathering data to track heart health. This extra feature may not be necessary for average users.
Because of the easy syncing capability of the Withings Health Mate app, we recommend this scale for people already using fitness trackers and smartwatches. The combined metrics and data tracking will help manage and motivate you to achieve your health and fitness goals.
Best Budget: Pohl Schmitt Smart Digital Scale
Why It Made The Cut: This affordable scale can track 24 users, making it perfect for small fitness studios, personal trainers, or others who want to measure data for a large group.
- Weight Capacity: Up to 400 pounds
- Compatibility: Works will all smartphones
- Materials: 8mm thick tempered glass
- Step-On technology, no tapping or power button required
- Easy-to-read large LCD display
- 13 measuring functions
- Affordable price
- You’ll need a third party app to sync to Apple
- Must manually transfer data to Fitbit and Google Fit
If you’re curious about trying a smart scale but you’re on a budget, the Phil Schmitt Smart Digital Scale is available for much less than the others on our list. The overall look and design is surprising given the price.
The scale offers four sensors that provide metrics on your weight, BMI, Body Fat Rate, Fat-free Body Weight, Subcutaneous fat, Visceral Fat, Body Water, Muscle Mass, Skeletal Muscle Rate, Bone Mass, Protein, BMR and Body Age. To enable this data collection you have to first set up your profile to include personal information including your height, sex, and age.
You’ll need to install the Fitdays app to collect, analyze, and store data collected from the scale. While the app pairs with other fitness apps used with smartwatches, the data doesn’t sync automatically. You’ll need to manually transfer metrics. Similarly, you’ll need to install a third party app in order to sync Apple health data into your Fitdays app.
Best for Outdoor Fitness Enthusiasts: Garmin Index S2 Smart Scale
Why It Made The Cut: We recommend this scale for outdoor fitness enthusiasts because of the syncing capability and outdoor workout focus of the Garmin Connect app. The software is designed to complement your other Garmin devices such as their smart fitness GPS and watches.
- Weight Capacity: Up to 400 pounds
- Dimensions: 12.6 x 12.2 x 1.1 inches
- Weight: 4.4 pounds
- Supports up to 16 users
- High resolution color display
- Customizable data display
- Works best with other Garmin devices
The Garmin S2 is a second-generation scale that’s an improvement on their previous model in a few ways. Most significantly they’ve added connectability to up to seven WiFi networks, reduced the overall dimensions, and improved the data display. The scale allows you to customize a display name for each user (up to four standard letters), which is helpful when sharing with others. The app makes it easy to customize which data you want displayed on your scale. Simply drag the toggle switch from on to off to hide data you don’t want to see on the screen.
With improved, built-in wireless connectivity, the Garmin S2 Smart Scale works through the Garmin Connect app. While it’s possible to use this scale only with your smartphone app, when you dive deep into the Garmin Connect app you see how well it can connect with other Garmin devices. We tested this scale and found the overall design to be attractive, the color display large and easy to read, and the Connect app easy to install and navigate.
Designed to support data for an impressive 16 users, this might be a good choice to share with members of your cycling, hiking, or running club. This scale will show you the physical results of your hard training, and allow you to set goals and share information with other users. As the most expensive smart scale on our list, this scale makes the most sense if you’re already using other Garmin smart gear.
Best for Fitbit Users: Fitbit Aria Air Bluetooth Digital Smart Scale
Why It Made The Cut: Fitbit is a powerful player in the smartwatch fitness tracking market. If you’re already using Fitbit products, this scale is a great way to automatically sync data and track your progress.
- Weight Capacity: Up to 400 pounds
- Dimensions: 11.8 x 11.8 x 1 inches
- Weight: 3.9 pounds
- Syncs with Bluetooth
- Backlit LCD display
- Easy smartphone set up
- Designed for compatibility with Fitbit trackers and watches
- Measures weight only
The Fitbit Aria Air is the only smart scale offered by Fitbit. The company used to offer the Aria Air 2 (which was more expensive and offered additional metrics) but that model has been discontinued. If you’re already a Fitbit user and most interested in tracking your weight, then the Aria Air is a great scale to consider. It’s reasonably priced and designed to sync wirelessly with the Fitbit app, so Fitbit users can gather weight data and track their overall fitness progress.
That said, there is no built-in WiFi; the Aria Air works with Bluetooth technology that sends your weight data to the Fitbit app. Unlike many other smart scales on our list, the Aria Air only measures weight and doesn’t measure other body metrics like fat or muscle content. However, with the integration of data collected and set up on the Fitbit app, you’ll be able to track your BMI and other data collected by your Fitbit watch or tracker.
Best Design: QardioBase2 Wifi Smart Scale and Body Analyzer
Why It Made The Cut: The QardioBase2 Smart Scale and Body Analyzer is best for design, not only for its circle shape, but also because of its option for users to choose smileys (instead of numbers) for weight display.
- Weight Capacity: 6.7 pounds
- Dimensions: 13.4 inch diameter x 0.9 inch tall
- Weight: 6.7 pounds
- WiFi- and Bluetooth-enabled
- Haptic feedback, vibration once you’re done with each measurement
- Safe for pregnant women and people with implanted medical devices
- Micro USB cable for charging
- Supports up to five users
The QardioBase2 is a second-generation model with a few important improvements from the previous version. The company has improved the scale’s stability (users will no longer find any wobbling issues), and now offers both rechargeable batteries and a micro USB cable for charging. The QardioBase2 is WiFi- and Bluetooth-enabled, and you can control it from your smartphone through the Qardio app. QardioBase2 integrates with Apple Health, Apple Watch, and Android Wear. Qardio is compatible with iOS, Android, and Kindle.
This scale measures weight, BMI, body fat percentage, and muscle, bone and water composition. It can handle up to five users, which makes it a good choice for a smaller household. The Qardio app allows you to choose the mode that works best for you: a normal mode for seeing all your body metrics, weight only mode, smart feedback mode which generates smileys instead of numbers, and pregnancy mode. Features like the circle design, smiley face option, and vibration when measurement is done, set this scale apart from the others.
Things to Consider When Buying the Best Smart Scale
Compatibility: When you’re considering a smart scale, pay attention to the ability of the scale to sync with your smartwatch or fitness tracker. While you can use basic functions with a smartphone alone, most customers who buy smart scales already own a smartwatch, and are adding this product to an overall digital fitness lifestyle. The Pohl Schmitt scale, Withings Body+ and QardioBase2 scales are the most flexible at syncing with other devices. In particular, the Withings and QardioBase2 scales are good choices if you’re looking for easy syncing, as both sync automatically once set up. The Garmin and Fitbit scales, meanwhile, are best used with the same brand of smartwatch or fitness tracker. When paired with their same brand these scales offer users a lot of options and data, most powerfully seen with the Garmin scale and Garmin Connect app.
Metrics: Another important feature to look for is the amount and type of metrics you want to gather. Full-body metrics use electrical impulses to determine fat, bone, and muscle mass and can help you get a deeper understanding of your overall health. This data is especially powerful when paired with your smartwatch or fitness tracker information. If you’re most interested in keeping track of your weight and syncing to your fitness tracker, there’s probably no need to buy an expensive smart scale that also offers full-body composition metrics.
Multiple Users: Finally, you want to consider the number of people who will be gathering and tracking data. All the scales we recommend are capable of tracking multiple users. The Garmin and Pohl Schmitt can handle the most users if that’s important for you. Multiple users on the Withings scale will be able to set up quick four-letter names to help identify them. Multiple users with the Fitbit scale will each need to have their own Fitbit account.
Q: How do smart scales work?
Full body metric smart scales use BIA (Bioelectrical Impedance Analysis) which sends an electrical current from one foot through the whole body to the other foot. The speed of the current determines the percentage of fat, water, muscle, and bone in the body. Smart scales also rely on your input of personal information, such as your sex, age and height.
Smart scales are designed to be used on a hard, flat surface. If your scale will be resting on carpet, you’ll need to install carpet feet to level it . In order for the scale to collect body metrics, you’ll need to stand on it with dry, bare feet. The scale will then send the data directly to your smartphone using either Bluetooth or WiFi signals. Smart scales are controlled by a smartphone app designed by the manufacturer. Most smart scale apps will also allow for syncing with other apps that gather health data, like Apple Health and Google Fit.
Q: Are smart scales worth it?
If you’re already using a smartwatch or fitness tracker, a smart scale is worth having as a companion to help measure the progress of your fitness routines. Digital fitness tools like smart scales can also help motivate users to stay on track by sending reminders and incentives. Gathering data wirelessly is a quick and easy way to stay aware of your health. Full body metrics can be more useful than simply tracking weight, as weight alone doesn’t always provide a full picture. Noting the decrease of fat and increase of muscle mass can help you see the real-time results of your workouts.
Q: Are smart scales harmful?
Smart scales are not harmful for most users, however individuals with pacemakers should not use full body composition scales. These scales send small electrical currents which can interfere with the implanted electronic device within the body. It is safe, however, for pacemaker users to use weight-only measuring smart scales. The QardioBase2 offers a setting for weight only, which would be a safe choice.
Smart scales are a powerful tool to add to your digital fitness lifestyle. Capable of gathering total body composition metrics — which include muscle, fat, bone, and water content — they can help provide a more complete analysis of your health. Syncing smart scales with your smartwatch or fitness tracker tracks can help motivate you to meet your fitness goals.
