Best smart scales 2025: expert tested and rated
As a fitness editor, I’m the first person to tell you that there are far more important metrics to track than your weight alone. That’s why I recommend the best smart scales, which can track your body composition, heart rate, and BMI, and can show you your progress over time, over traditional bathroom scales.
All of the best smart scales have a connected app that is easy to navigate and understand. Most models also 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.

Best smart scale overall
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 easy to navigate, 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
Wyze has a history of launching budget-friendly smart scales, but the Scale X is a huge improvement over the older scales, as it also has 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 this does it for you.
It’s compatible with Fitbit, whereas the previous Wyze Scale S wasn’t. All of your in-depth body data is displayed clearly within the app, with a body weight trend graph and dedicated sections for each metric.
Tapping 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 downside with this cheap 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 you can see your muscle mass, it doesn’t give you any context, like whether it’s in a good range. This is nit-picking though — all-in-all, it’s a fantastic, affordable scale.
Best premium smart scale
This is one of the priciest smart scales on the market right now. But it’s also one of the most comprehensive, 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 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.
The downside here is that, unlike other models, you can only see your body weight on the scale itself, you’ll need to use your phone to see the rest. Plus, If extreme accuracy is vital for you, the Renpho only tracks in 0.2 lbs increments, rounding up.
In some cases, this could hinder your ability to know whether a weight loss or gain goal is on track. If this is the case for you, it might be worth looking into more expensive smart scales, such as the Withings Body Smart, which tracks in 0.1 lbs increments.
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.
Which Withings smart scale should you buy?
Should you buy the Withings Body Smart, the Body Scan, or the Body Comp? This depends on your budget, and the metrics you care about. The Body Smart is the most affordable, and has most of the body composition metrics most people would need. It doesn’t have things like the advanced heart rate features, or the nerve health score, but I’d argue most people don’t need these, making the Body Smart my 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.
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.
Are smart scales Wi-Fi or Bluetooth?
The difference between a smart scale and a regular bathroom scale is that these smart models sync your data to another device. They need to do this with a wireless connection, either Bluetooth or Wi-Fi.
Generally, you find that cheaper models only use Bluetooth, so you’ll need your phone with you, connected to the scale, and an app to receive the data open. These usually only work with a single account as well, so are less ideal for multi-person households.
If you have the budget for it, a Wi-Fi scale is the more versatile and convenient option. You need to set up the network connection initially, but then you can leave your phone elsewhere, step onto the scales, and the data automatically syncs.
Because the process is automated, you need to set up individual users on the scale. So while this is useful for regular household measurements, it means that it’s a bit less suited to casual weigh ins from visitors, as the data syncs to the owner’s account.
