[Update: March 2021] Working out with Apple Watch? These smart scales sync weight with iPhone


Apple Watch can help you stay motivated to exercise and improve your health, and smart scales that sync data to the iPhone can be a fun and useful way to track your progress. If you want to easily collect your 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 Health app

HealthKit is Apple’s framework on iOS for sharing health data with granular permission between Apple’s built-in Health app on the iPhone and third-party health apps like from the makers of smart scales. When you weigh yourself, the HealthKit-compatible scale syncs the data to its own app, then shares the data in Apple’s Health app alongside 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)

Withings branding can be confusing. That’s because Withings was bought by Nokia and re-branded, then sold to its founder with the original name. Any version should work fine. Branding aside, the hardware is really reliable and works great with HealthKit. Each model comes in white or black with Body+ also available in pastel sand.

  • Withings Body ($59) is great for simply capturing your weight plus body mass index and having it appear in Apple’s Health app
  • Withings Body+ ($99) captures weight and BMI in addition to body composition: water, muscle mass, fat mass, and bone mass
  • Withings Body Cardio ($149) includes everything from Body+ as well as heart rate readings

Withings Body+ is my go-to HealthKit scale solution and has been for years. The Health Mate app is great for viewing weight data on charts that can show information in different ways than Apple’s Health app. I never have to worry about weight data showing up in the Health app after weighing either.

The cheaper Withings Body model is my suggestion for customers on a budget or who only care about weight and BMI logging. The pricier Withings Body Cardio adds a rechargeable battery for its premium price, but the built-in heart rate detection is a tough sell in the age of Apple Watch.

Withings also has a cellular smart scale on the way, but consumers shouldn’t pay much attention to this version that’s geared more toward health professionals. The existing Bluetooth + wifi scales are great for home use.


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

If you’re not impressed with the Withings options, Qardio has an attractive but pricey alternative. QardioBase 2 ($149) captures weight, body fat percentage, and body mass index data for the Health app on iPhone. Its round design and clever display makes it look more modern than Withings as well.

QardioBase 2 also features a built-in rechargeable battery that lasts 12 months between charges like Withings Body Cardio, not consumable batteries that need to be replaced after 18 months like Withings Body and Body+.

I purchased one of these a few years back and had trouble with weight data appearing in the Health app, but your experience may vary today.



iHealth makes lots of HealthKit-compatible accessories including smart scales. iHealth Lina ($39.99) tracks both weight and BMI which sync with Apple Health. iHealth Nexus ($79.99) also tracks body fat, body water, plus muscle & lean & bone mass.


Budget Picks

  • Eufy BodySense Smart Scale (Amazon)

While I don’t have experience with Eufy, the brand has sub $40 smart scale. Eufy BodySense captures weight, BMI, body fat percentage, bone mass, muscle mass and other measurements that sync with the Apple Health.
