While fitness trackers are a great tool to keep track of your steps, heart rate and exercises, smart scales are a great companion as they can help you monitor your weight too.
In fact, many of the companies that make fitness trackers and other wellness wearables also make smart bathroom scales to give you even more information about your body.
Smart scales don't just provide more metrics about your body, but connect up to the internet too. This means you can keep an eye on your weight or body fat percentage from your phone. With many apps allowing you to set goals, chart your progress over time and share your stats with other apps and services.
But it's not just the fact they can pair up with an app that makes smart scales worth your time and money. Many aren't just focused on weight, but tell you all kinds of things, such as your body fat percentage, muscle mass, bone mass, BMI and much, much more. This is a much better way of seeing the big picture of your health – your weight can only tell you so much.
We've been working hard to find the best smart scales for you. Throughout the list of products below, we've taken into consideration the features on offer, the design and the price of each product. That means below you should find the best option for your next pair of scales.
The best smart scales overview:
- Withings Body+
- Withings Body
- Eufy Smart Scale
- Fitbit Aria 2
- Garmin Index Scale
- Fitbit Aria Air
- Withings Body Cardio
1. Withings Body+
Our favorite pair of smart scales
Metrics: Weight, BMI and body mass | Connectivity: Android and iOS app, Wi-Fi and Bluetooth | Display: 2.4 x 1.6-inch display | Battery life: 18 months, uses AAA batteries | Dimensions: 12.8 x 12.8 x 0.9 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes, up to eight
Our favorite pair of smart scales on the market right now used to have the Nokia branding on them, but now it has switched backed to the Withings title that you may remember.
Withings offers three different scales – you’ll learn more about the other two below – and this is the mid-range option in terms of feature set and price. We like the extra features you get here over the cheapest model, and it also comes with a more premium design.
It's light enough that you can easily move it around your bathroom, it will sync all of your data directly to an app called Health Mate that’s available on iOS and Android, and it will track some interesting stats too. For example, it will be able to monitor your weight like you'd expect but it can also track your BMI as well as your body composition.
It’s able to give you an idea of the amount of water, bone and muscle in your body. That’s something you won’t get with every pair of smart scales, and if you’re looking to build up some muscle rather than just lose weight you’ll find this a must-have metric.
2. Withings Body
A cheaper alternative
Metrics: Weight, BMI | Connectivity: Android and iOS app, Wi-Fi and Bluetooth | Display: 2.4 x 1.6-inch display | Battery life: 18 months, uses AAA batteries | Dimensions: 12.8 x 12.8 x 0.9 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes, up to eight
Our second favorite choice also comes from Withings, and while the feature set isn’t as extensive as the choice above it does have a much more attractive price that many will be happier with when buying bathroom scales.
This is the pair you'll want to buy if you just want an easy way to track your weight within an app with relatively little hassle. It will connect to the Health Mate app, so whatever scores you’re getting will be recorded there and it will give you extra insight over time as you weigh yourself.
That’s the app you’ll use if you have a Withings fitness tracker too, so you can have all of your details in the same space. If you have a Withings wearable you can even have yesterday’s step count appear at your feet as some motivation on a morning too.
This isn’t capable of the extra body composition features we’ve seen on other products like the ones coming up below, but it’s that bit more affordable, making it an appealing budget option.
3. Eufy Smart Scale
One of the best (and cheapest) you can buy
Metrics: Weight, body fat, water, muscle mass, bone mass, BMI, BMR | Connectivity: Android and iOS app, Bluetooth | Display: 3.1 x 1.3 in / 80 x 32 mm **Battery life:** AAA batteries | Dimensions: 12 x 12 x 1 in / 300 x 300 x 26 mm | Colors: White or black | Units tracked: Pound / Stone / Kilogram | Multiple users?: Yes, up to 16
Generally considered one of the best smart scales on the market, Eufy has proved yet again you don't need to pay over the odds for good tech (the brand also has an affordable and awesome range of robot vacuums).
For under £30 / $30, these smart scales allow you to keep tabs on all kinds of metrics, including weight, BMI, BMR, muscle mass, bone mass and more. All of the data is stored in the Eufy app, which is easy-to-use and allows you to benchmark your stats with other users.
Up to 16 people can use the Eufy smart scales, which is likely more than you'd ever need. But it's great there's no tiny limit like there are with other products.
4. Fitbit Aria 2
Limited scope, but a lovely design
Metrics: Weight, BMI, body mass | Connectivity: Android and iOS app, Wi-Fi and Bluetooth | Display: N/A | Battery life: N/A, uses AA batteries | Dimensions: 12.3 x 12.3 x 1.3 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes, up to eight
Already own a Fitbit fitness tracker or smartwatch? It's likely this will be the best option to track your health in full as the Fitbit Aria 2 connects directly into the official app to give you a full insight into your fitness.
Most of the features from the Body+ are available here, so you'll be able to keep an eye on your body fat percentage and lean mass here as well. All of this data will then be plugged into the Fitbit app, and it will give you insight into your health over time.
The price is where the Withings scales win out here, but you may be able to find a suitable deal on the Aria 2 and if you already own a Fitbit product it's a great choice as the two will work seamlessly together.
5. Garmin Index Scale
The best option for Garmin fans
Metrics: Weight, BMI, body mass | Connectivity: Android and iOS app, Wi-Fi and Bluetooth | Display: N/A, LCD | Battery life: 9 months, uses AA batteries | Dimensions: 13.8 x 12.2 x 1.2 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes, up to 16
Much like the Body+ scales, the highlight here is that these scales are capable of measuring your body fat and water percentage as well as your muscle mass and bone mass.
The Garmin Index Scales work well, but the price is higher than the Body+ so we've put it lower down this list. If you're looking for some top-end features and you like the design of these scales, these are a perfectly suitable option for you.
We particularly recommend these if you already have a Garmin fitness tracker or running watch, as the integration with the app works remarkably well and allows you to have all of your health stats in one place.
If you're an amateur athlete who wants insight into their body beyond what a fitness tracker strapped around your wrist can offer, be sure to consider these smart scales.
Fitbit Aria Air
Fitbit's budget smart scales
Metrics: Weight, BMI | Connectivity: Android and iOS app, Bluetooth | Display: LCD display | Battery life: not stated, uses AAA batteries | Dimensions: 12.3 x 12.3 x 1 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes
If you're a Fitbit user who doesn't want to splash out on the Aria 2, or just doesn't need all its features, there's an alternative in the Aria Air, which is more of a budget version of the 2.
The Aria Air might not have some of the features of the Aria 2 like body composition monitoring, and the ability to change users and view different stats on the scales (instead you can only see weight), but most people might not care about these features, making the Air the preferable choice.
Add to that the fact the scales automatically sync to your Fitbit app, it's a great companion to people who already use Fitbit fitness trackers or wearables, as it lets you track your weight as well as your exercise.
6. Withings Body Cardio
More expensive, and we're not sure why
Metrics: Weight, BMI, body mass and heart rate | Connectivity: Android and iOS app, Wi-Fi and Bluetooth | Display: 2.4 x 1.6-inch display | Battery life: A year, rechargeable | Dimensions: 12.8 x 12.8 x 0.7 inches | Colors: White or black | Units tracked: kg, lb, st lb | Multiple users?: Yes, up to eight
The Withings Body Cardio scales are some of the best-looking that we've seen that could adorn your bathroom, but a lot of what's useful here is also in the Body+ at the top of this page.
When the Body Cardio scales launched, they had a feature called Pulse Wave Velocity that measured the stiffness of the aorta, which is something that can lead to further health issues.
In January 2018, the company was asked to remove the feature by the FDA in America, and that means you can no longer use this feature and there's no clear word on whether it will return.
That means a lot of the benefits of this scale are lost, apart from that slightly more premium design and the fact these scales can also measure your heart rate. If you already own a fitness tracker or smartwatch, it's likely you'll have a heart rate tracker so you won't need this feature on your smart scales.
We do like the design of the Body Cardio, but we don't think that the look and heart rate feature is a big enough upgrade to justify the extra money you'll be spending compared to the Withings Body+ scale. That said, if you really prefer the design and you don't mind spending more then this is a good pair of scales all the same.
