Best smart scales in 2024
The best smart scales help you keep tabs on more than just your weight. These scales have sensors to track your body composition, heart rate, and BMI, with the data easily accessible on your phone to track your progress.
Most models even connect to some of the best workout apps so that you can see all your health and fitness stats in a single place, combined with the data recorded by your fitness tracker or smartwatch.
But to see how accurate these scales really are, we put them to the test, checking the measurements against a reference scale and looking at how easily you can sync your data to your phone or fitness tracking app.
Overall, we felt that the Withings Body Smart was the best smart scale for most people, but to get the most from it, you need to be invested in the Withings app and ecosystem. So, if you’re after an alternative, we’ve rounded up our other favorite options to help you find the smart scales that are right for your goals.
The quick list
The Withings Body Smart 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.

If you don’t need a scale with quite as many features, Withings’ Wi-Fi scale, Withings Body, delivers the basics in a stylish package. We compared it to the Body Cardio and a $20 digital scale, and the scale was within 0.2 pounds of both.

Best smart scales you can buy right now
Best smart scale overall
At $99, this may be one of the highest-spec smart scales you can get for under $100. Withings have really outdone themselves with the Body Smart, including visceral fat index, body composition, and even hydration level metrics.
This can be used for casual hydration tracking, general health statistics, or for those in training: the scale comes with athlete, pregnancy, eyes closed, and baby modes, so hopefully all members of the family can join in, if they so desire.
While the Withings app is endlessly usable, with helpful information stuffed into its every corner, some extra features like Health Improvement Score and Body Score are locked behind a paywall. It’s an extra $99 (yearly) subscription if you want to take full advantage of everything Withings offer.
For those getting into fitness, or just wanting to keep a general check-up of their health, the Withings Body Smart is a great place to start, with enough information on the app to teach you everything you need to know.
Best budget smart scale
The Wyze Scale X is among the newest budget smart scales from Wyze, and it’s got one stand-out improvement — the option to track your muscle mass percentage. Of course, you could always figure this number out on your own by dividing muscle mass by body weight.
But if you don’t feel like pulling out your calculator, shilling out an extra $10 is worth it. It’s also compatible with Fitbit, whereas the previous Scale S isn’t. All of this in-depth body data is displayed clearly within the app, with a body weight trend graph and dedicated sections for each metric.
apping on a section will show your results, along with a slider bar and a definition of the specific measurement. It’s an easy-to-use scale, with the option to store eight different profiles. There are also luggage, pet, and baby modes, which we appreciated during testing (especially when packing for a long-haul flight).
The downsides with this cheap and cheerful smart scale is the app, which doesn’t really give you an awful lot of information to support the wealth of data. While it’s great for a user to know their muscle mass, there’s little information there to indicate whether that number is considered acceptable for overall health. This is nit-picking though, all-in-all, it’s a fantastic, affordable machine.
Best premium smart scale
At $399, this is one of the priciest smart scales on the market right now. But it’s also one of the most high-tech, with a built-in ECG, vascular health monitor, nerve health monitor, on top of the standard Withings metrics like segmental body composition, hydration levels, and visceral fat index.
It has a similar feature set to the Withings Body Smart, but with more detailed measurements (it detected our reviewer’s right arm had 4% less muscle than their left) and it generates a 3D image of your body so you can see insights like which is your dominant leg. It’s impressively in-depth.
But the most notable inclusion here is the ECG, which monitors your heart rhythm and can help alert you to irregular patterns or atrial fibrillation. Withings has always focused on the health aspects of fitness tracking, so its not surprising to see the feature pop up on the brand’s most expensive smart scales.
However, it’s questionable how useful it is. Unless you stand on the scales several times a day, you only get a snapshot of your heart health. If this is something you’re interested in tracking and want to stay in the Withings ecosystem, its hybrid smartwatches like the Withings ScanWatch 2 also have ECG built in.
If your doctor has advised you to look into your cardiovascular health, this is a great device to keep-up-to-date with your heart, as long as you pair it with regular check-ins with a licensed medical practitioner.
Best smart scale for body fat
The Renpho Smart Body Fat Scale is the next best thing for most fitness buffs. It’s easy to use and provides a breadth of information for those who want to track their body composition changes.
There are 13 metrics tracked using the scale’s built-in bioelectrical impedance analysis tech to measure body fat percentage, skeletal muscle percentage and overall muscle mass, fat-free body weight, subcutaneous and visceral fat, body water, bone mass, and more.
The large LED display is clear and easy to read, instantly showing weight. To see additional metrics, you’ll need to have the app connected and your phone with you, as the scale’s display only shows body weight.
If detailed and in-depth metrics about your health are important to you, the Renpho scale is an easy choice to make. It is affordable, hassle-free, and extremely informative. The ability to track trends and save or share them allows for informed decision-making when you are working towards various health goals.
Best value Withings smart scale
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 scale for reliability
The Eufy Smart Scale P3 is definitely one to add to your shortlist. If you need a smart scale that offers you comprehensive insights into your health and body composition, the P3 has you covered with 16 bioelectrical impedance analysis metrics.
These are: weight; BMI; body fat; body fat mass; lean body mass; visceral fat; subcutaneous fat; bone mass; muscle mass; skeletal muscle mass; protein; BMR; heart rate; water levels; body age; and body type.
The EufyLife companion app is decent, displaying data and trends, while also including other useful health features like a food and calorie tracker. What’s more, there are numerous modes for pets, babies, pregnancy, pacemaker users and athletes.
This smart scale is let down by a few glaring issues, though, which may make similarly priced rivals from the likes of Withings and Garmin a better choice for you. Onboard controls are extremely frustrating to use, while use detection did not work at all for us in testing.
The P3 can only pair with Apple Health and Fitbit, too, so if you use a different health tracking app, you’ll want to avoid this scale. Finally, there’s no “eyes closed” mode as you’ll find on Withings scales, and the EufyLife app nags you to get on the scale every day — both could be problematic for those who are triggered by weight.
Best smart scales for Fitbit users
The Fitbit Aria Air is the Google-owned brand’s smart scale, designed to integrate nicely with your other Fitbit devices with the data neatly synced to your Fitbit app for monitoring and analysis.
It’s straightforward to use as well, with an easy set up and all you need is 3 AAA batteries for power. However, it doesn’t sync the data via Wi-Fi, only by Bluetooth, so you’ll need to your phone nearby to capture the recordings.
Since it needs a direct connection to the Fitbit app, it also doesn’t create individual profiles on the scales, making set up even quicker. But the major downside to this approach is that the scales can’t measure anything other than your weight.
So, if you’re hoping to get more insights, like body fat or muscle mass, you’ll need to look for an alternative scale. For the price, the Aria Air is disappointingly light on features, so it’s best only for Fitbit users who just need weight measurements.
Best smart scale for Garmin users
Like the Fitbit Aria Air, the Garmin Index 2 is designed to work seamlessly with your favorite Garmin wearable devices. The data syncs via Wi-Fi to your Garmin account, so you can view the measurements alongside your other health and fitness data.
You can set up multiple users (up to 16 profiles) and the scales can automatically detect who is using them. The small display then cycles through your weight, BMI, trends, and other metrics like body fat percentage and muscle mass.
So, it has the edge over the Fitbit device here, but suffers from the same setback or draw, depending on your point of view: its integration with other Garmin devices. There are other smart scales, like the Eufy P1, which capture the same measurements, but without tying you into a specific ecosystem.
Also tested
The smart scales in the guide above aren’t the only ones we’ve tested, as we’re regularly trying out connected bathroom scales so that we can recommend the models that are actually worth your money. But if you’re after more options, these are the smart scales that didn’t quite make the cut.
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.
Fitbit users could even connect one of the best Fitbits to Fitbit smart scale models, helping you keep on top of your daily health and fitness stats.
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.
FAQs
Why get a smart scale?
Smart scales can do so much more than just report back to you on your current weight. Moreover, weight can fluctuate throughout the day based on various factors like water retention. A smart scale can provide feedback detailed metrics to health apps on your phone and send data wirelessly to your devices.
Obsessing over a number on the scales is not a true indication of health, but if your goal is to lose weight, a smart scale could help you understand your body. Many linked apps can also display the data in helpful and motivating ways, which could help you hit your goals.
Not fussed about the numbers? Stick to a simple set of scales and save your dollars.
Are cheap smart scales accurate?
During testing, the budget-friendly smart scales were reasonably accurate. Of course, there’s always some variation between models, but the relative accuracy (measurements on a single device) is the most important factor to consider, as this will help you keep track of changes.
Generally, the main reason that the scales are cheap is that they lack the features of the more premium models. So, some don’t come with Wi-Fi and only sync via Bluetooth, or don’t have multi-user support.
