Smart scales are a great companion to your exercise routine, and Apple Fitness+
Along with Apple’s Fitness app and the Apple Watch’s Workout & Activity apps, a smart scale gives you feedback and data on your current fitness and health.
And if you subscribe to and use Apple Fitness+, smart scales can let you know if your chosen Apple Fitness+ classes are working and helping you accomplish your weight and body composition goals.
What is an Apple Health Scale?
Smart scales can connect with your phone via an app that communicates with its scale and gives you all the information you need.
These apps integrate with Apple Health, which is good if you want to have all your health and fitness information in one app.
And more importantly, smart scales allow you to avoid entering manual weight information by syncing that information automatically with the Health app on your iPhone!
Apple Health scales are just smart scales that offer an app that integrates with the Apple Health app. So, they are just Apple Health-compatible scales.
Plus, if you share your scales with other members of your family or household, smart scales track each person’s weight best when family members’ weights are significantly different.
If you and your family members are within a few pounds of each other, the scales don’t auto-track, and you may need to identify who is getting weighed.
A couple of words of caution:
First, while your smart scale may track a host of body measurements (and some even track your heart rate), Apple limits its Health app to the following body measurements: height, weight/body mass, lean body mass, body mass index, body fat percentage, and waist circumference.
Additionally, research indicates that the body fat composition metric on smart scales often underestimates your body fat percentage.
Use a smart scale to track changes over time
We find that the best way to use a smart scale is to track your body measurement trends over time.
When you consistently use the same scale, a smart scale is great at showing your progress or lack of progress in changing your body composition from month to month or year to year.
Tips to get the most out of your smart scale
- Try to weigh-in at the same time every day.
- Don’t use the scale if you’re dehydrated or overhydrated. And avoid drinking caffeine or alcohol in the hour leading up to your weigh-in.
- Don’t use the scale immediately after exercise or after bathing/swimming. Wait at least 30 minutes post-workout or post-showering.
With that out of the way, let us move on with the reviews!
1: Withings Body+ – Best overall
Out of all the scales on this list, the Withings Body+ may be one of the priciest ones, but it may also be the best.
It’s compatible with the following:
- Google Fit
- Apple Health
- #1 BEST-SELLING SMART SCALE In the US. One of the smartest digital scales for body weight, making it...
- BODY COMPOSITION - The withings scale functions as a bmi measurement tool or body fat analyzer. This...
Like most high-end smart scales, the Withings Body+ can keep measurements for up to 8 users while connecting to your smartphone with Bluetooth and WiFi.
It keeps track of each person based on weight history, and each person can use the same account or create separate accounts (using Withing’s Health Mate app.)
This scale can track fat percentage, muscle, bones, and even water percentage and follow a baby’s weight independently in case you are pregnant.
While the scale has a small display to give you basic information, you can use the Health Mate app to track everything – including the history/progress of all your metrics.
Speaking of the app, you can find it on iOS and Android. Plus, it’s also Alexa-compatible.
Do keep in mind that Withings has tons of other products too. Things like smartwatches, fitness trackers, and more.
You can use the same app to gather info on steps, heart rate, and more. Otherwise, you can rely on Apple Health to do the same with 3rd party smart options.
- Good build quality
- Its app is natively compatible with other smart products
- Tons of metrics with a pregnancy tracker (Or Baby Mode, as Withings calls it)
- Alexa compatibility is a welcome addition
- A bit pricey
2: RENPHO Scale – Best value
Cheap scales that are good are hard to find. Cheap smart scales, even more so. App development on its own is something that costs quite a lot.
But as far as budget Apple Health-compatible scales are concerned, we’d say that RENPHO’s offering is one of the best – if not the best.
It works with:
- Apple Health
- Google Fit
- Samsung Health
- Smart App Works with Fitness Apps. Over millions of happy global users. Easy setup app works with...
- 13 Essential Body Fat Measurements. The RENPHO Smart BMI scale measures weight, Body Fat, BMI,...
Don’t get fooled by the low price. RENPHO offers plenty of metrics. In many cases, even more than severely more expensive scales.
This includes fat percentage, water, muscle mass, bone mass, visceral fat, subcutaneous fat, and metabolic age.
You can use the app to track your progress over the last week, month, or year.
You can also set goals, create user accounts for multiple family members, and store data for up to eight users. Renpho’s scale automatically recognizes each user based on their weight.
Unfortunately, RENPHO doesn’t have any smartwatches or fitness bands that we know of – which means that you won’t be able to build a smart RENPHO ecosystem even if you want to.
But since the scale is compatible with Apple Health, you can connect it with any other Apple Health-compatible device and have all your data in one place.
The only downside of this scale is that it only works with Bluetooth (though there is a pricer WiFi version.) This may restrict you in terms of range – but it’s a small price to pay, considering how much you get for less than $30.
- Relatively cheap
- It provides all the essential metrics that you’ll need and more
- Despite the low price, its app is compatible with both Apple Health and other alternatives
- No advanced WiFi features, such as pregnancy tracking (which is to be expected at this price point)
3: QardioBase X – Our high-end pick
Qardio is one of the most popular brands there. So, it’s no surprise that one of its smart scales is among our top picks.
The QardioBase X smart body composition scale is one of the most expensive picks on our list, but it’s also the only one offering many features.
You can use it with the following:
- Apple Health and Apple Watch
- Samsung Health
- Google Fit
- Alexa and Siri
- BODY COMPOSITION SCALE - QardioBase X measures your weight (lb, kg, st), calculates BMI and tracks...
- BEST SMART SCALE - According to CNET, an independent website that reviews technology and consumer...
As you no doubt already expected, the QardioBase X offers everything that its cheaper variants do and more.
Fat percentage calculator, muscle mass, bone weight, support for multiple users, water percentage calculator, and anything related to body composition.
Additionally, there is a large display and pregnancy tracking. And it works on almost any floor surface, including carpets and rugs!
Needless to say that at this price point, you get WiFi or Bluetooth syncing. Another minor plus is the addition of a rechargeable battery.
So instead of replacing AAA batteries, you have to recharge the scale with a standard USB-C cable once per year, and that’s about it.
- The larger display and rechargeable battery are both welcome additions
- Works with all the major health apps (Apple Health, Samsung Health, and Google Fit)
- More expensive than others
4: Withings Body Cardio – Best for heart rate tracking
This is pretty much the Withings Body+, the only difference being that it also offers heart rate tracking and cardiovascular health monitoring. Just like with the cheaper variant, you can use this with the following:
- Google Fit
- Apple Health
- #1 WORLDWIDE - FIRST SMART SCALE WITH CARDIO CHECK-UP. It's a one of a kind weight scale for body...
- HEART RATE MONITOR - Get heart rate with the built-in heart monitor plus an indication of your...
We didn’t pick this one as the best Apple Health scale since most of you will probably use a smartwatch or smart band.
If you already have another device that supports heart rate monitoring, what’s the point in spending the extra money to have it on your scale?
Still, if money isn’t an issue or you are not interested in buying another smart heart-rate monitoring device, Withings’ offering may be worth considering.
Also, unlike the cheaper variant, the Body Cardio comes with a rechargeable battery.
A single charge can give you enough battery life for up to a year, and while this isn’t a huge deal, it’s a welcome addition nonetheless.
- Heart rate tracking
- The rechargeable battery is a welcome addition
- Integrates well with other Withings products
- One of the most expensive picks on this list
- Small display despite the large price
5: Etekcity – Best budget Apple Health scale
This is worth checking out if you are looking for a cheap Apple Health scale. It has all the essential features you’ll ever need and works with iOS and Android.
To be more specific, it’s compatible with the following:
- Apple Health
- Google Fit
- Samsung Health
- And Fitbit
- FSA / HSA eligible
- FIRST RATE QUALITY: Don't settle for less. As the no.1 SELLING BRAND of body weight scales in the...
You can expect to find all the basic body composition metrics such as fat percentage, muscle percentage, BMI, bone density, and more for a total of 13 biometric body composition measurements when using Etekcity’s VeSync app.
There’s also a Baby Mode to help you weigh and track your baby and a zero-current mode to safely measure your weight and BMI during pregnancy. You can even use Baby Mode to track your pet’s weight!
You will only get Bluetooth connectivity at this price point without WiFWiFi AAA batteries instead of the rechargeable ones that premium variants tend to offer.
The app also supports progress tracking to see your results over days, weeks, or months. Alternatively, you can also rely on Apple Health for that.
And that’s about all there is to it. Just a smart scale that offers all the basics that smart scales are supposed to deliver.
- Cheapest offering on this list
- It offers all the “basic” body composition metrics and some advanced measurements, too, such as fat percentage, water percentage, muscle, and more
- Probably the best value
- No rechargeable batteries (which is to be expected at this price point
6: iHealth Nexus Body Composition Scale – Our readers’ favorite scale
If you’re looking for a scale that tracks your weight, body composition metrics, and fitness data, look no further than our readers’ favorite scale, iHealth’s Nexus Wireless Body Composition Scale.
It’s compatible with both:
- Apple Health
- Google Fit
- iHealth smart digital scales for body weight is dedicated to empowering healthier lives. Come and...
- Accurate Readings: The iHealth Nexus Pro body weight scale always keep an eye on your body to help...
This medical-grade level body composition scale not only tracks and measures your weight, BMI, and body fat but also records your body’s water, lean, and muscle mass.
Additionally, it can track changes in your bone mass and tell you how much your bones weigh–an essential measure for women in menopause.
The scale and its companion app, iHealth MyVitals, use all that information and give you a visceral fat rating, helping you keep track of the positive or negative changes in how much belly fat you have.
You can use the iHealth Nexus with the whole family, up to 8 people. And the scale auto-recognizes people based on their weight history. And family members don’t need to use the app each time they weigh themselves!
So all family members need to do is step on the scale, and iHealth Nexus differentiates each person from the others as long as each person’s weight is different by 5 pounds.
If two people have the same weight, they can use their assigned user number on the scale to let it know who is getting weighed.
The scale also uses low-energy Bluetooth 4.0 and can run up to 6 months on four AAA batteries!
- Affordable and reader recommended
- It offers many body composition metrics and some advanced measurements
- No rechargeable batteries
What types of scales are most accurate?
Digital scales are generally more accurate than their analog counterparts – they don’t even have to be smart.
However, just because a scale is digital doesn’t mean it will be accurate. Therefore, it’s always worth paying attention to both user reviews and professional reviews.
Does the Withings Scale work with Apple Health?
Yes. The Withings app can seamlessly integrate with the Apple Health app, and the same goes for all of our picks on this list.
Can body fat scales be wrong?
When it comes to just weight metrics, most scales are generally not deviated by a lot. However, things get more complicated when measuring body fat percentage and other things.
That is because scales send a weak electrical impulse through your body and then calculate your fat percentage depending on the current encounters’ resistance level.
They also need an algorithm–and if the formula is not accurate, the results will not be too accurate either.
According to our sources, the most accurate readings were off by about 21%. Thus, yes, body fat scales can be wrong.
But thankfully, you can still measure with decent accuracy the trends in your body fat percentage, whether it is increasing or decreasing.
Are smart scales worth it?
That’s a question for you to answer. If you want our opinion, the cheapest smart scales worth it come at just a bit more than 20 bucks – which is not much more expensive than a traditional scale. So, yes. We’d say they are worth it.

Could you also describe how each scale manages multiple users? My old FitBit Aria (now died) automatically recognised me from my wife because we have significantly different weights. We don’t want to be firing up phones and apps every morning just to get weighed…
Most of the scales auto-recognize users based on their weight and weight history. However, if two (or more) people are similar in weight, usually less than 5 pounds difference between them, then they may need to either use the app to identify themselves or use a function on the scale itself to change the user id
Withings does NOT auto synch with Apple Health – iOS makes sure of that. You have to open Apple Health, the HealthMate, the swipe down on HealthMate to force a refresh. If you don’t do this, Withings weights will not synch to Apple Health.
Withings Health Mate app should auto-sync to Apple Health. If that’s not working, try the following:
1) Make sure you allow the Health Mate app to refresh in the background on your phone. In the Health mate app, open your profile and tap the Settings icon at the top. Choose System authorizations and toggle on Background app refresh or background data.
2) Open the Apple Health app and choose your profile icon. Scroll down and tap Apps > Health Mate and turn on categories for both sections Allow Health Mate to Write and Allow Health Mate to Read. If these are already on, toggle them off, wait 20 seconds, and then back on.
3) After doing the above, restart your iPhone.
If you still have problems, remove the Health Mate app from your iPhone, restart your iPhone, and then open the App Store and reinstall the app–signing in and giving all permissions again.
If those steps
It seems like the ETEKCITY one only syncs the weight data to Apple.
For the rest, you have to load their app and give them significant personal information.
I would like to see more information about which of these would simply work with a standard app (Apple Health) without requiring their own.
I agree, I need another app like I need another hole in my head. A simple, reliable, auto sync with Apple Health would be perfect.
Apple designed the Health app to interact with devices via apps.
So when you weigh yourself using a third-party device that supports Apple HealthKit like a scale, the device first syncs your data to its own app and then shares that data to Apple’s Health app.
So it’s functioning the way Apple intended. Now, if Apple designed their own scale, we assume it would directly work within Apple Health just like any other Apple product, i.e. the Apple Watch.
I know it’s a pain to have to download another app and then wait for that app to then sync to Apple Health.
Hi Beth. I bought 2 Etekcity smart scales and the body fat measurements are off by almost 50%. Do any of the smart scales have accurate body fat measurements?
Oh, that’s terrible. Withings scales are considered the gold standard and have been clinically tested (open link to see Withings research studies.)
Withings offers the body composition feature on its Body+ and Body Cardio scales. Their budget option, the Body scale, does not include body composition.
The main difference between these models is that the Body Cardio also records your heart rate and estimates your vascular age. And the Body Cardio includes a rechargeable battery, while the Body+ requires AAA.
They also just released a premium model, the Body Comp, that offers a host of new features, including a visceral fat analysis, nerve health score, and even an air quality analysis. Of course, it’s also quite expensive when compared to other scales.
Hope that helps,
Do Apple Health sync ALL DATA SETS from analysis scales ? as I don’t see half of the data types synced/option on Apple Health, they seam 2 b well behind !!!
Eg Body Mass Index (BMI), Body Fat Percentage, Visceral Fat, Body Water Percentage, Muscle Mass, Bone Mass, Skeletal Muscle Percentage, Protein Percentage, BMR and Metabolic Age etc etc, that SCALES can now able to analyse
I’m looking for scales that Apple Health sync/take MAXIMUM DATA SETS from, if anyone knows about this scenario ?
Unfortunately, Apple Health doesn’t support many of the metrics that your smart scale can read and track through its own companion app. Additionally, depending on the make and model and how the scale integrates with the Apple Health app, it may only send certain readings to Apple Health.
Yes, it’s confusing.
From reviewing the current Apple HealthKit developer documentation, at this time, Apple Health supports the following body measurements: height, body mass (weight), body mass index, lean body mass, body fat percentage, and waist circumference, along with wrist temperature.
While the list is limited compared to some of the scale’s own apps, Apple is always incorporating more health metrics–usually when the annual update of iOS occurs each year (sometime in September.)
Due to these limitations, we recommend you track your body measurements using the companion app–for example, use Withings Health Mate app if you own a Withings scale. We still advise you to connect to Apple Health so you have the basic body measurement info in the app and when Apple adds additional metrics, those will also sync.
We will update the article to point out the limitations of tracking your body measurements via Apple Health and the advantages of using the companion app.
Thank you for pointing this out!
