So you just bought an Apple Watch, you’re ready to start syncing up all your cool health and fitness apps and you need a smart bathroom scale that’s compatible. Using a smart scale is a convenient way to sync up all your data without having to manually enter data into your chosen app whenever you use the scale to measure your weight, BMI, body fat or any other metric. A smart scale can send data directly to your Apple Watch, iPhone or indeed any other device but you need to ensure the devices and apps you are using are compatible with each other. This post discusses the best scales that work with Apple Watch.
Wifi vs bluetooth connectivity
If you having already been doing some research you will know that smart scales either use Wifi connectivity (where the scale send the data to the cloud via Wifi) or Bluetooth connectivity (where the scale transmits data directly to your device using Bluetooth). For Bluetooth connectivity to work the scale has to be able to directly send data to your Apple Watch. While most Bluetooth smart scales can transmit to Apple devices like iPhones and iPads, it’s not as common for these scales to be compatible with Apple Watch (the only we’ve seen recently is the Qardiobase 2). Therefore it’s generally safer to get a Wifi connected smart scale so that it doesn’t matter that you’re using an Apple Watch – the scale will send the data to the cloud which can by synced with your Apple Watch. For wifi scales to work though, make sure there is a good connection in the bathroom or wherever you keep the scale – this means the scale should be within a certain distance to your wireless router.
What health apps do you want to use on your Apple Watch?
Another important thing to consider when choosing a smart scale for your Apple Watch is what fitness/health app you want to use. If you are currently using, say, MyFitnessPal then you want to ensure that the scale you buy can send directly to that app on your Apple Watch. In a nutshell, you want to get a smart scale that talks to your chosen app, regardless of the fact you are using Apple Watch or any other device. So this is what you need to do:
- Think about/decide what app(s) you want to use
- Ensure that the app is available on Apple Watch
- Choose a scale that can sync with that app
Here’s some apps that work well with Apple Watch
Using Apple Health with your Apple Watch
Speaking of apps, if you are generally using Apple products, you might want to consider Apple Health as a central hub for your health and fitness data. Apple Health is Apple’s all-in-one health app designed to be your one-stop shop for all health and fitness information. It consolidates health data from iPhone, Apple Watch, and third-party apps you already use, so you can view all your progress in one convenient place. There are four distinct categories in Apple Health: Activity, Sleep, Mindfulness, and Nutrition.
However, keep in mind that when it comes to data from smart scales not all data can be transferred to Apple Health. Apple Health allows you to store information about weight, BMI and body fat percentage. So if your smart scale and its native app are measuring lots of additional metrics like body mass, water mass etc. you will need to track that within the scales’ native app.
What metrics do you want to measure?
There are different smart scales that can measure different things. These scales can go by different names – body composition scales, body fat scales, body fat analyzers, among others. Most people however want to know 2 basic indicators – weight and maybe BMI. All smart scales should be able to measure these metrics. If you want to measure body fat, body fat percentage, bone mass, or water mass, there are scales for that too. There are some questions about their accuracy and how body composition scales work, but that’s another discussion. Suffice to say the more metrics you want to measure the more complex it gets and the more expensive the scale is likely to cost.
There are numerous features that individual scales may have or not have. This includes how many users can be tracked, can it show trends over time, and other features that you may or may not want. All I can say is that don’t get too caught up in fancy features and metrics that you may never use because that will bump up the price unnecessarily.
So here are the smart scales that I think are best for the Apple Watch. We have generally chosen scales here that sync with a variety of apps but again the most important thing is that the scale works with YOUR chosen app(s), whatever they may be.
Smart scales for your Apple Watch
Nokia Body + Body Composition Scale
Nokia recently acquired the Withings brand so all Withings products are now Nokia (this was previously the Withings Body +). Nokia Body + is a next-generation wifi scale that uses new technology for more accurate weight readings. Nokia scales are integrated with many 3rd party apps (over 100 of them), including Apple Health, so you are likely to find the app you use works with Nokia. The native app for the scale Health Mate is pretty comprehensive and it is available on the Apple Watch. Alternatively you can sync Health Mate to Apple Health and use Apple Health as your main source of data.
I do like the trend screen which shows the previous 8 weigh-ins, so you can immediately see what your progress is like. If you use the Wifi connectivity it even gives a daily weather report so that you can “plan your outfit and day’s activities.” Interesting, but probably not that useful to be honest! Overall, we like this smart scale because of its many features and the fact their app is directly available on the Apple Watch. Nokia Body + comes in white or black. If you are not interested in the advanced metrics and just weight and BMI the Nokia Body is also an option.
Works with these apps: food tracking apps such as MyFitnessPal, Lose It!, and Weight Watchers, or training apps like Runkeeper, Runtastic and MapMyRun. Over 100 integrated apps.

The Qardiobase 2 is the most recent version of the Qardiobase, manufactured by Qardio, a company that specialises in health-tracking devices and apps. The Qardiobase 2 is an interesting product with some unique features. This is a full body composition scale with a sleek modern look and unique visual feedback providing a happy, neutral or sad face depending on your previous measurements. It’s a small but personal touch that adds to the design. It takes 8 AAA batteries to run which is a lot more than normal. Because of the circular shape of the scale, earlier versions of the Qardiobase had some complaints about the stability of the scale, but it seems they have addressed those issues.
Qardiobase measurements can be viewed directly on the Qardio app which is available on an Apple Watch. To view Qardiobase measurements on your Apple Watch just select the weight icon. You will be able to view your most recent weight measurement, as well as your body fat and muscle percentage, if you have Normal Mode enabled. As an alternative you can also sync Qardio data with Apple Health.

Fitbit Aria 2
You will surely have heard of Fitbit, the leading activity tracker company on the market. In a way, Fitbit trackers compete with Apple Watches but don’t worry – this shouldn’t be an issue. The Fitbit Aria scale is integrated with many 3rd party apps so as long as those apps are available on your Apple Watch it should all be synced up.

How to sync your bluetooth smart scale directly with your Apple Watch
While many smart scales work by sending their data to the cloud which indirectly then updates an app on your Apple Watch, there are some smart scales sync directly with your Apple Watch. At the moment the only one we are aware of is the Qardiobase 2, but follow these steps to pair your devices:
- Put your Bluetooth accessory in pairing mode using the instructions that came with it.
- On your Apple Watch, tap Settings > Bluetooth. Your Apple Watch will search for nearby Bluetooth accessories.
- Choose your Bluetooth accessory.
- If asked, enter a passkey or PIN
So just to reiterate – first thing you need to do is to ensure your preferred health app(s) is available on the Apple Watch. If you are using Apple Health as your main health app, then you have lots of options because all you need to do is find a smart scale that syncs with Apple Health and the data will show on your Apple Watch. The Nokia Body + and Qardiobase 2 are options where you can use their own native apps since they are available directly on the Apple Watch.
