Data is a useful tool in any battle, especially if you’re opting to wage war against your waistline in an attempt to be healthier. Back in 2007, I bought a dirt-cheap scale and drew my own graph sheets in order to chart my weight’s downward progress after a rough year at university. I think that while 2007 me wouldn’t be pleased with my own fitness journey, he would love the fact that the process is entirely automated, and affordable. Consequently, allow me to take you (and him) on a journey to pick the best smart scale to help you on your own journey toward behavior change.


There are valid reasons to weigh yourself, but your self-worth shouldn’t be defined by the number that shows up between your feet. If you’re looking to alter your body shape, that figure could go up as your waistline goes down, since muscle weighs more than fat. Dr. Anne Swift, Director of public health teaching at the University of Cambridge, said that “weighing yourself too often can result in [you] becoming fixated on small fluctuations day-to-day, rather than the overall trend over time.” Swift added that “it’s sometimes better to focus on how clothes fit, or how you feel, rather than your weight.”

(A meta-analysis from 2016 found there may be some negative psychological impact from self weighing. A 2018 study, however, said that there may be a positive correlation between regular weigh-ins and accelerated weight loss. It can be a minefield, and I’d urge you to take real care of yourself and remember that success won’t happen overnight.)

What to look for in a smart scale


A weighing scale that weighs you is probably the top requirement, right? One thing to bear in mind is that, with all these measurements, the figures won’t be as accurate as a calibrated, clinical scale. Consequently, it’s better to focus on the overall trend up or down over time, rather than the figures in isolation.


Most scales will either connect to your phone over Bluetooth, or to your home’s WiFi network, and you should work out your regular weighing routine ahead of time. A lot of lower-end, Bluetooth-only models will only record your weight when your phone is present and don’t keep local records. That means if you routinely leave your phone outside the bathroom, you could lose that day’s stats. WiFi-connected scales, on the other hand, post your stats to a server, letting you access them from any compatible device. But you need to be mindful that there’s a small risk to your privacy should that information be compromised.

Bone density

The stronger your bones, the less you’re at risk from breaks and osteoporosis, which you should keep in mind as you get older. Clinical bone density tests use low-power x-rays but higher-end scales can offer an approximation from your own bathroom. These tests pass a small current through your feet, measuring the resistance as it completes its journey. The resistance offered by bones, fat and muscle are all different, and your scale can identify the difference.

Body fat percentage and muscle mass

Fat and muscle are necessary parts of our makeup, but an excessive amount of either can be problematic. Much like bone density, a scale can identify both your body fat and muscle mass percentages using Bioelectrical Impedance Analysis (BIA). This measurement tests how well your body resists the electrical signal passing through your body. (It’s a rough rule of thumb that you should have a 30/70 percent split between fat and muscle, but please consult a medical professional for figures specific to your own body and medical needs.)


A lot of scales offer a BMI calculation, and it’s easy to do since you just plot height and weight on a set graph line. Body Mass Index is, however, a problematic measurement that its critics say is both overly simplistic and often greatly misleading. Unfortunately, it’s also one of the most common clinical metrics and medical professionals will use it to make judgements about your care.

Pulse Wave Velocity

French health-tech company Withings has offered Pulse Wave Velocity (PWV) on its flagship scale for some time, although regulatory concerns meant it was withdrawn for a period of time. It’s a measurement of arterial stiffness, which acts as a marker both of cardiovascular risk and also other health conditions. I’ve had anecdotal reports that PWV scales have sent people to the doctor, where they’ve found they were close to a cardiac event. It’s worth saying, as with all of these technologies, that there is limited, albeit positive, research into how accurate these systems are.


Less a specification and more a note that smart scales have displays ranging from pre-printed LCDs or digital dot matrix layouts through to color screens. On the high end, your scale can show you trending charts for your weight and other vital statistics, and can even tell you the day’s weather. If you are short-sighted, and plan on weighing yourself first thing in the morning, before you’ve found your glasses / contacts, opt for a big, clear, high-contrast display.

App and subscriptions

You’ll spend most of your time looking at your health data through its companion app, and it’s vital you get a good one. This includes a clear, clean layout with powerful tools to visualize your progress and analyze your data to look for places you can improve. Given that you often don’t need to buy anything before trying the app, it’s worth testing one or two to see if you vibe with it.

Several companies also offer premium subscriptions, unlocking other features – including insights and coaching – to go along with your hardware. Fitbit and Withings both offer these services, which you may feel is worth the extra investment each month.

Data portability

Using the same scale or app platform for years at a time means you’ll build up a massive trove of personal data. And it is, or should be, your right to take that data to another provider when you choose to move platforms in the future. Data portability is, however, a minefield, with different platforms offering wildly different options, making it easy (or hard) to go elsewhere.

All of the devices in this round-up will allow you to export your data to a .CSV file, which you can then do with as you wish. Importing this information is trickier, with Withings and Garmin allowing it, and Omron, Xiaomi, Eufy and Fitbit not making it that easy. (Apps that engage with Apple Health, meanwhile, can output all of your health data in a .XML file.)


It’s not a huge issue but one worth bearing in mind that each scale will either run disposable batteries (most commonly 4xAAA) or with its own, built-in battery pack. Sadly, all of our crop of smart scales use batteries, adding an environmental and financial cost to your scale life. That’s just about forgivable for scales that cost under $100, but this stretches even to the highest-end models. When you’re spending more than that on a device, the lack of a rechargeable cell feels very, very cheap indeed.

The smart scales we tested

For this guide, I tested six scales from major manufacturers:

Mi (Xiaomi) Body Composition Scale 2 ($29.99)


Our cheapest model, Xiaomi / Mi’s Body Composition Scale 2 is as bare-bones as you can get, and it shows. It often takes a long while to lock on to get your weight, and when it does you’ll have to delve into the Zepp Life-branded app in order to look at your extra data. But you can’t fault it for the basics, offering limited weight and body composition for less than the price of a McDonald’s for four.

Fitbit Aira Air ($49.95)

Fitbit, now part of Google, is the household name for fitness gear in the US, right? If not, then it must be at least halfway synonymous with it. The Aria Air is the company’s stripped-to-the-bare bones scale, offering your weight and little else, but you can trust that Fitbit got the basics right. Not to mention that most of the reason for buying a Fitbit product is to leverage its app anyway.

Anker Eufy Smart Scale P2 Pro ($79.99)

Eufy / Anker

Eufy’s Smart Scale P2 Pro has plenty of things to commend it – the price, the overall look and feel (it’s a snazzy piece of kit) and what it offers. It offers a whole host of measurements, including Body Fat, Muscle Mass, Water, Body Fat Mass and Bone Mass, as well as calculating things like your Basal Metabolic Rate (the amount of calories you need to eat a day to not change weight at all) all from inside its app. In fact, buried beneath the friendly graphic, the scale offers a big pile of stats and data that should, I think, give you more than a little coaching on how to improve your lifestyle.

Shortly before publication, Anker – Eufy’s parent company – was identified as having misled users, and the media, about the security of its products. Its Eufy-branded security cameras, which the company says does not broadcast video outside of your local network, was found to be allowing third parties to access streams online. Consequently, while we have praised the Eufy scale for its own features, we cannot recommend it without a big caveat. 

Omron BCM-500 Body Composition and Scale with Bluetooth ($89.99)

Given its role in making actual medical devices, you know what you’re getting with an Omron product. A solid, reliable, sturdy, strong (checks the dictionary for more synonyms) dependable piece of kit. There’s no romance or excitement on show, but you can trust that however joyless it may be, it’ll do the job in question. The hardware is limited, the app is limited, but it certainly (checks synonyms again) is steady.

Joking aside, Omron’s Connect app is as bare-bones as you can get, since it acts as an interface for so many of its products. Scroll over to the Weight page, and you’ll get your weight and BMI reading, and if you’ve set a goal, you can see how far you’ve got to go to reach it. You can also switch to seeing a trend graph which, again, offers the most basic visualization on offer.

Garmin Index S2 ($149.99)

Garmin’s got a pretty massive fitness ecosystem of its own, so if you’re already part of that world, its scale is a no-brainer. On one hand, the scale is one of easiest to use, and most luxurious of the bunch, with its color screen and sleek design. I’m also a big fan of the wealth of data the scale throws at you – you can see a full color graph charting your weight progress, and the various metrics it tracks in good detail. If there’s a downside, it’s that Garmin’s setup won’t hold your hand, since it’s for serious fitness people, not newbies.

Withings Body Comp ($209.95)

At the highest end, Withings’ flagship Body Comp is luxurious, and luxuriously priced, a figure I’d consider to be “too much” to spend on a bathroom scale. For your money, however, you’ll get a fairly comprehensive rundown of your weight, body fat, vascular age, pulse wave velocity and electrodermal activity. Its monochrome dot matrix display may not be as swish as the Garmin’s, but it refreshes pretty quickly and feels very in-keeping with the hardware’s overall sleek look. If there’s a downside, it’s that Withings ditched the rechargeable battery found in the Body Cardio (its former flagship, and an excellent scale I’d recommend if it were within the parameters of this guide) in favor of AAA batteries. Which, when you’re spending this much on a scale, makes me feel very nickel-and-dimed.

The best cheap smart scale: Fitbit Aria Air, Mi Body Composition Scale 2

It’s very competitive at the low end, and Xiaomi and Fitbit offer dramatically contrasting products for a very low price. Fitbit’s scale has far fewer features, but has better build quality, is faster and more reliable than its cheaper rival. Crucially, it also leverages Fitbit’s own app, which is a long refined and easy-to-use app that offers clean, easy-to understand visualizations.

Xiaomi, meanwhile, offers weight and some basic body composition checks, although this extra data is only visualized inside the app. From a data perspective, the Xiaomi has the edge, but its companion app – formerly Mi Fit, now branded as Zepp Life – is terrible. The lag time for each weigh-in, too, leaves a lot to be desired with the Xiaomi, although I had no qualms about its accuracy.

When I was a kid, and complained about something, my nan would say “look, you can either have a first class walk or a third class ride.” And Fitbit’s scale here is the very definition of a first class ride – polished, snappy and with a world-class app by its side. The Xiaomi, meanwhile, offers more for your money, and charges less, but both hardware and software lack any sort of polish. It’s therefore up to you if you’d rather the first class walk or the third class ride.

The best scale for people who want features (and aren’t fussed about security): Eufy’s P2 Pro

Most feature-rich smart scale
Eufy Smart Scale P2 Pro


Well, this is awkward. Not long before this guide was published, it was revealed that Eufy is in the midst of a massive security issue. Researchers found that its security cameras, which were promised to be secure, allowed internet users to access the stream using VLC player. Consequently the high praise for Eufy’s P2 Pro I have as a scale will need to be moderated by the fact that we don’t yet know how deep the company’s promises around privacy and security really run.

It’s unfortunate, as the scale does leap head-and-shoulders above the competition at this level, and it surpassed my expectations by quite a bit. The ease of use was one thing, but the depth of data made available in the app, and the way it presents that information, is fantastic. While I don’t think the Eufy Life app is better than, say, Withings’ class-leading Health Mate, it offers exactly what a would-be weight-watcher would need.

The fact you can get plenty of your vital statistics graphed by hitting two buttons helps you visualize your progress, but the stat dashboard laying out everything, including your BMR, is so useful. If you’re going all Quantified Self, you could theoretically calculate your daily calorie intake to the finest of fine margins looking at this thing every morning.

The best scale for athletes: Garmin Index S2

Garmin’s scale impressed us with its hardware, and we think it’s the best scale for those that already calculate their BMR on a daily basis.

$149.99 at Amazon

I’m very partial to Garmin’s Index S2, but I also think it’s the sort of scale that needs to be used by people who know what they’re doing. Almost everything about the hardware is spot-on, and the only fly in its ointment is the low refresh rate on its color screen. I can’t say how upsetting it was to see the display refresh in such a laggy, unpolished manner, especially when you’re spending this much money. But that’s my only complaint, and the rest of the hardware (and software) is otherwise pitch-perfect. If you’re looking to alter your body shape, this probably isn’t the scale for you – it’s the scale you buy once you already calculate your BMR on a daily basis.

The best scale for the worried well: Withings Body Comp

Naturally, if you’re looking for a machine that’ll cater to your every whim and hypochondriac urge, then Withings’ Body Comp is the way forward. It’s a luxury scale in every sense of the word, and you should appreciate the level of polish and technology on show here. Apart from the batteries, which I’ve already said is a cheap and nasty way to save money given that you’re dropping this much money on a product.

The group of people who think it’s reasonable to spend $200 on a scale is, especially with food and energy prices spiking, a fairly small one. But if you’re the sort who already spends hand over fist to keep your body in check, this is probably justifiable as an “investment.” Knowing all of the extras about your nerve health and arteries is a bonus, but let’s be clear and say this isn’t the scale for everybody. Hell, you might have second thoughts even if you do have a subscription to Good Yachting Magazine.
