Training with Apple Watch? These smart scales sync your weight with your iPhone [July 2023]

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 your weight and other measurement data in the Health app on iPhone (and soon on iPad), the trick is to find a scale that works with HealthKit.

Sync your weight with the Health app

HealthKit is Apple’s framework on iOS for sharing health data with granular permission between Apple’s built-in Health app on iPhone (and iPad this fall) and third-party health apps like those from smart scale manufacturers. When you weigh yourself, the HealthKit-enabled scale syncs the data to its own app, then shares the data in the Apple Health app along with other health-related data collected by Apple Watch.

Withings

• Body Wi-Fi Scale (Amazon) under $60
• Body+ Body Composition Wi-Fi Scale (Amazon) under $100
• Body Cardio Wi-Fi Smart Scale with Body Composition and Heart Rate (Amazon) under $180

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

• Withings Body ($59) is great for simply capturing your weight plus BMI and showing it in Apple’s Health app
• Withings Body+ ($99) captures weight and BMI as well as body composition: water, muscle mass, fat mass and bone mass
• Withings Body Cardio ($179) includes everything from Body+ and heart rate readings

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

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

Withings also has a mobile smart scale on the way, but consumers shouldn’t pay much attention to this version which is geared more towards health professionals. Existing Bluetooth + Wi-Fi scales are great for home use.

Qardio

• QardioBase X (Amazon) under $130

If you’re not impressed with Withings options, Qardio has an attractive but pricey alternative. QardioBase X ($129) captures weight, body fat percentage, and BMI 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, non-consumable batteries that need to be replaced after 18 months like Withings Body and Body+. Plus it’s USB-C like most Apple devices.

Budget choices

• Eufy BodySense Smart Scale (Amazon)
• GE Smart Scale (Amazon)
• While I have no experience with the Eufy, the brand has a $30 smart scale with over 12,000 Amazon reviews and a 4.7-star rating. Eufy BodySense captures weight, BMI, body fat percentage, bone mass, muscle mass, and other metrics that sync with Apple Health.

GE also has a HealthKit-compatible smart scale with a list price of $44.99. The GE model is an Amazon’s Choice product and sometimes offers a 20% coupon in addition to an 11% discount.
