The 6 Best Smart Scales of 2023, Tested and Reviewed

Today, you can find a “smart” version of just about anything. Throughout the last year, we’ve tested smart TVs, smart couches and smart twinkly lights, to name just a handful of examples. In the evolution of smart home devices, bathroom scales are no exception. The best smart scales do so much more than tell you your weight, and they provide a serious upgrade to your clunky old bathroom scale.

Smart scales measure weight, of course, in addition to various other body composition metrics. In addition, they connect to your devices and an app via Wi-Fi or Bluetooth. When you step onto a smart scale with bare feet, a weak electric current flows through the body, allowing the device to perform a body composition analysis. In this way, the best smart scales of 2023 help you track progress toward your wellness and weight loss goals and encourage you to maintain a healthy lifestyle.

Many smart scales can also connect with other fitness and health apps so that all your health information can be recorded and accessed in one place. This makes it easy to track progress across multiple body composition and wellness metrics. While your scale might traditionally live in the bathroom, these advanced features make smart scales a great addition to your home gym. Along with fitness mirrors, wearable fitness trackers and other smart gym products, smart scales really will make it feel like you’re living in the future.

We’re happy to say the SPY team has just finished testing the best smart scales, and we’ve narrowed it down to a list of five. Several of these products were also featured in the first-ever SPY Smart Home Awards 2022. So to find the best smart scale for your fitness goals, read on!

Key Specs:

Material	Tempered glass, aluminum
Connectivity	Bluetooth, Wi-Fi
Max. Weight Capacity	396 pounds
Body Composition Metrics	weight, BMI, muscle mass, body fat, total body water, bone mass, heart health

The Withings Body Cardio smart scale is the most comprehensive and informative smart scale we tested. While other smart scales measure a higher quantity of metrics, we think the Withings Body Cardio offers the most crucial, useful and accurate information so you won’t be overwhelmed. It automatically detects up to eight users and tracks their health data accordingly. You can even receive a weather report on the scale’s display screen to round out your morning routine. We love that it has a rechargeable battery so you’ll never have to worry about digging through your junk drawer searching for a fresh set of AA batteries.

The best smart scales can easily sync up with fitness trackers, and this is easy to do with the Withings app. The Withings Health Mate app is the most supportive smart scale app that we tested, offering personalized information based on your individual data and trends. The app not only tracks your data, but it also helps you interpret that data so you aren’t weighed down by extra, unnecessary measurements.

This smart scale offers a full body composition analysis in addition to reading your heart rate and calculating your vascular age. The only downside in collecting this data is it takes almost a minute to run through the entire analysis, which means you’ll be spending more time atop this smart scale than your traditional bathroom scale. We also found you have to remain exceptionally still in order to collect an accurate heart rate. Despite that, if you’re passionate about health and wellness, this is the best smart scale for you.

Key Specs:

Material	Alloy steel
Connectivity	Bluetooth, Wi-Fi
Max. Weight Capacity	397 pounds
Body Composition 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, heart rate

The Eufy P2 Pro made a big splash in 2022, and it’s packed with smart features that make it a serious contender for the best smart scale of 2023. We also appreciate that it’s much more affordable than the Withings Cardio. We had no issues with the Eufy Smart Scale P2 Pro app when it came to connecting our devices to the scale’s smart features. This scale has a slim design and takes up much less space than our old scales, so it can fit into even the smallest bathroom nooks. This Eufy smart scale boasts an impressive detailed body composition analysis measuring 16 health metrics for an unlimited number of users.

The Eufy app offers users the unique experience of creating a 3D digital avatar to document progress. While we enjoyed creating 3D models of ourselves in the app, if you have serious weight and wellness goals this feature might become overwhelming or even discouraging if your progress is ever stalled or stagnant. 

Key Specs:

Material	ITO-coated glass, tempered glass
Connectivity	Bluetooth
Max. Weight Capacity	400 pounds
Body Composition Metrics	weight, body fat, heart rate, lean body mass, BMI, muscle mass, muscle mass, visceral fat, basal metabolic rate, bone mass, metabolic age, protein, body water

The Wyze Scale X is a great smart scale option for people on a budget. We found Wyze scales to be more sturdy on our hardwood floors, and they didn’t slide at all when stepping on or off. We love the layout of the app, which makes it easy to access informative descriptions of each of the health measurements this scale can collect. You can view all results at once, or select a preferred time so you can assess only morning readings or night readings which allows for more accurate trends.

This smart scale cannot collect heart rate, but the app does offer a unique heart rate collection option using your fingers and your phone’s camera and flashlight. We found this to be surprisingly accurate, though possibly inconvenient since all your health data can’t be collected at once. During testing, we thought we had a few instances of connectivity issues when some of our weight readings didn’t appear as data points on the graph. Once we clicked on the trend lines, however, we found our data had been collected and documented as trends on the graphs rather than specific data points. Still, for the price, this is a great option.

Key Specs:

Material	ITO-coated glass
Connectivity	Bluetooth
Max. Weight Capacity	400 pounds
Body Composition Metrics	weight, body fat %, heart rate, lean body mass, BMI, muscle mass, visceral fat, basal metabolic rate, bone mass, metabolic age, protein, body water %

We love stepping on this Wyze Smart Scale. It offers a satisfying sort of click as you sink into it which reminds us of a more traditional bathroom scale. It’s sturdy, small and doesn’t slip on hardwood floors. It comes with all of the same features as the Wyze scale above, with the option to measure heart rate directly on the scale with bare feet. It does require an extra step to open the app and select “Measure” when you desire to collect a heart rate.

It presents information the same way as the other Wyze scale, in a graph depicting only a few specific data points. This Wyze smart scale offers the same informative descriptions of the body metrics, but we found navigating the app to be a little less intuitive than with the Wyze Scale X.

This smart scale collects 12 body composition metrics and offers the average healthy-standard measurements to compare your metrics against. For this price, this scale is a great entry-level option for people who are curious about their health but don’t really need the bells and whistles of our other top picks.

Key Specs:

Material	Tempered glass
Connectivity	Bluetooth, Wi-Fi
Max. Weight Capacity	396 pounds
Body Composition Metrics	weight, body water %, BMI, muscle mass, bone mass, fat mass

This smart scale from Withings is another great choice if you’re looking for a scale with smart features but don’t want to break the bank. Aside from measuring heart rate, this Withings smart scale can measure all the same metrics as the Withings Body Cardio.

We did find that this scale wasn’t particularly sturdy on hardwood floors, but if your bathroom floor is tiled, you should be fine. This scale can be programmed to display daily weather reports, a convenient Withings perk that we love. This scale was easy to set up and easy to use, though slightly bulkier than the ultra-sleek Withings Body Cardio. If you want a Withings scale for a slightly lower price, this is the best smart scale for you.

Key Specs:

Material	Tempered glass
Connectivity	Bluetooth, Wi-Fi
Max. Weight Capacity	400 pounds
Body Composition Metrics	weight, BMI, skeletal muscle mass, bone mass, body water %, body fat %

There’s a lot of attention to detail in the design of the Garmin Index S2. It’s sleek, constructed from premium materials like tempered glass with a customizable display that can even show the weather and temperature conditions when you’re weighing yourself.

When it comes to monitoring your body’s changes, the Garmin Index S2 offers a myriad of metrics that serious users will appreciate. For example, we loved how the Garmin app for mobile was able to break down all of the data it gathered from our weigh-ins. In fact, after using it for a month, it was able to provide us with details about our weight trend.

How We Chose the Best Smart Scale: About our Testing Process

Our SPY team tested each scale multiple times per day, at various points throughout the day, for several weeks. During the testing process, our product reviewers considered the following criteria:

Accuracy and consistency: Our team evaluated each smart scale’s accuracy in measuring weight by testing each scale at the same times each day at several points throughout the day. We used 3-pound and 5-pound hand weights to increase our weight to test how our measurements would change. Each of the five scales was extremely accurate in measuring weight and never differed from each other by more than .1 pounds. We also tested heart rate measurements and found the camera and flashlight collection method used by Wyze to be the most consistent and accurate.

Ease of Use: We considered how easy it was to set up each smart scale and connect to the app’s features. We evaluated how easy it was to program the scales to collect different measurements and sync to multiple apps. We have included screenshots of the Withings Health Mate app and the Wyze app taken during our testing process below.

Quality of Materials: We considered how each scale felt. Does it feel sturdy and support our weight? Does it slide around when stepping on and off? Does it look aesthetically pleasing sitting out in our bathrooms?

Special Features: Do the measurements automatically sync to the smart scale’s app? Does it sync to other health and fitness apps? How many users does the smart scale support? How many special modes does the smart scale offer?
