[Update: September 2020] Do you train with the Apple Watch? These smart scales sync your weight with your iPhone

The Apple Watch can help you stay motivated to exercise and improve your health, and smart scales that sync data to your iPhone can be a fun and useful way to track your progress. If you want to easily collect weight and other measurement data in the Health app on iPhone, the trick is to find a scale that works with HealthKit. Here are some of the current options on the market:

Sync your weight with the Health app

HealthKit is Apple’s framework on iOS for sharing health data with detailed permission between Apple’s built-in health app on iPhone and third-party health apps from smart scale manufacturers. When you weigh yourself, the HealthKit-compliant scale syncs the data to its own app, and then shares the data in the Apple Health app with other health-related data collected by Apple Watch.

Prices will vary at different times, so check each link for the best cost comparison.


  • Body Wi-Fi Scale (Amazon)
  • Body + Body Composition Wi-Fi Scale (Amazon)
  • Body Cardio Wi-Fi Smart Scale with body composition and heart rate (Amazon)

Note that the Withings brand can be confusing. This is because Withings was bought by Nokia and rebranded, and then sold to the founder with his original name. When it comes to branding, the hardware is reliable and works well with HealthKit. Each model comes in white or black with Body + also available in the Pastel Sand option.

The basic model is great for just capturing your weight and making it appear in Apple̵

7;s Health app. The upgraded versions capture more data such as body fat percentage and BMI, which can be useful, although the more expensive heart rate model is not necessary if you use an Apple Watch.


  • QardioBase 2 Wireless Smart Scale and Body Analyzer (Amazon)

If you are not impressed with the Withings options, Qardio has an attractive option with some improvements. QardioBase 2 records the weight, percentage of body fat and BMI for the Health app on the iPhone, and the round design stands out. Qardio also has a decent Apple Watch app that shows you your latest catch measurements.

It also has a built-in rechargeable battery, not consumable batteries that need to be replaced after several months. Neither Withings nor Qardio have great iPhone apps, but they require little interaction when the scales are primarily used to fill in weight data in the Health app.


  • Small wireless scale (Amazon)
  • Core Wireless Body Composition Scale (Amazon)

iHealth makes many HealthKit compliant accessories, including smart scales. The cheaper Lite model looks like it may be on its way out, but it tracks both weight and BMI. The upgraded Core version also tracks body fat percentage and more.


  • Eufy BodySense Smart Scale (Amazon)
  • Runcobo Weight (Amazon)

Eufy has an attractive price that is not much higher than some basic scales on the market. You get weight, BMI, body fat percentage and other measurements that are synchronized with the Health app on iPhone. Runcobo is an Amazon top seller with 14 measurements in total and a five star rating.

Do you have your own smart scale that syncs with the Health app on iPhone? Share your recommendation in the comments below.
