Apple can help you stay motivated to practice and improve your health, and smart scales that sync data with the iPhone can be a fun and useful way to track your progress. If you simply want to collect your weight and other measurement data in the Health app on the iPhone, the trick is to find a scale that works with HealthKit. Here are some of the current options on the market:
9to5Mac Happy Hour
HealthKit is Apple's framework on iOS for sharing health data with detailed consent between the built-in Apple Health app on the iPhone and third-party health apps, such as from the creators of smart scales. If you weigh yourself, the HealthKit-compatible scale synchronizes the data with its own app and shares the data in Apple Health's app with other health-related data collected by Apple.
Withings / Nokia
The branding of Nokia / Withings can be confusing. This is because Withings has been purchased by Nokia and has been re-marked and subsequently sold to the founder with the original name. Apart from the fact that the hardware is reliable and works well with HealthKit. Each model comes in white or black.
The $ 60 base model is great for simply capturing your weight and appearing in Apple's Health app – and at that price it will likely quickly disappear. The updated versions contain more data, such as the percentage of body fat and BMI, which may be useful, although the more expensive heart rate model is not necessary if you are wearing an Apple.
- QardioBase 2 Wireless Smart Scale and Body Analyzer ($ 149: Amazon)
If you are not impressed by the Nokia / Withings options, Qardio has an attractive alternative with a few improvements. QardioBase 2 registers weight, body fat percentage and BMI data for the Health app on the iPhone and the round design stands out. Qardio also has a decent Apple app that shows you the latest recorded measurements.
It also includes a built-in rechargeable battery, non-consumable batteries that need to be replaced after a few months. Neither Withings nor Qardio have great iPhone apps, but they require little interaction when the scales are mainly used for filling data in the Health app.
HealthKit support from QardioBase 2 is a bit of a work-in-progress and often requires access to be turned on and off to activate synchronization in my experience. I prefer the design, so QardioBase 2 is the smart scale I use, but I really hope that HealthKit support improves.
iHealth makes many accessories that are compatible with HealthKit, including smart scales. The cheaper Lite model looks like it might be on its way, but it follows both weight and BMI for less than $ 100. The improved Core version also keeps track of body fat and more.
Eufy is not in the same class as other picks, but it does have an attractive price that is not much higher than some basic scales on the market. For less than $ 50 you get weight, BMI, body fat percentage and other measurements that sync with the Health app on the iPhone.
