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 iPad this fall) 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.

Withings
Body Wi-Fi Scale (Amazon) below $60 Body+ Body Composition Wi-Fi Scale (Amazon) below $100 Body Cardio Wi-Fi Smart Scale with Body Composition and Heart Rate (Amazon) below $180Withings 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 ($179) includes everything from Body+ as well as heart rate readingsWithings 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.
Qardio
QardioBase X (Amazon) below $130If you’re not impressed with the Withings options, Qardio has an attractive but pricey alternative. QardioBase X ($129) captures weight, body fat percentage, and body mass index data for the Health app on iPhone.
QardioBase X 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+. Plus it’s USB-C like most Apple devices.
