Whether you're working out with an Apple Watch or just trying to live a healthy lifestyle, smart scales that sync data to your iPhone can help you . will 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 iPad (starting with iPadOS 17), you'll need to find a scale that works with HealthKit.
Sync your weight with the Health app
HealthKit is Apple's iOS platform for sharing granular health data between Apple's built-in Health app on iPhone (and iPad this fall) and third-party ones applications. health apps, for example from smart scale manufacturers. When you weigh yourself, HealthKit-compatible scales sync the data with its own app and then transfer it to the Apple Health app along with other health data collected by Apple Watch.
- Wi-Fi Body Scale (Amazon) Under $60
- Wi-Fi Body+ Body Composition Scale (Amazon) under $100
- Body Cardio Smart Scale with Wi-Fi that measures body composition and heart rate (Amazon) under $150
Withings also has the most advanced smart scaler for $400, but the basic weight sync isn't worth the money.
- Withings Body ($59) is great for Easily determine your weight and body mass. The index and its display in the Apple Health app.
- Withings Body+ ($99) records weight and BMI in addition to body composition: water, muscle mass, fat mass, and bone mass.
- Withings Body Cardio ($179) includes everything in Body+ plus heart rate readings
Withings Body+ is a scalable HealthKit solution that I have been using for many years. The Health Mate app is great for viewing weight data in charts, which may display information differently than the Apple Health app. I never have to worry about my weight not showing up in the Health app after weighing myself. It's tested and trusted.
The cheaper Withings Body model is my suggestion for those on a budget or who only care about weight and BMI registration. The more expensive Withings Body Cardio adds a rechargeable battery for its premium price, but in the age of the Apple Watch, a built-in heart rate monitor is a harder sell.
- QardioBase X (Amazon) under $100
If you're not impressed with Withings, Qardio has an attractive but pricey alternative. QardioBase X ($100) captures weight, body fat percentage, and body mass index data for the Health app on iPhone.

Renpho is available on Amazon, it tracks a number of other metrics besides weight (and as someone who struggled with weight for decades and worked with a weight loss doctor, lost over 100 pounds and kept it off for 5 years, controlled diabetes, etc.) – the ~$20 Refo scale is within 10% across the board on a dozen or so body weight measurements, as is the MD scale, which costs well over $20K. It works with both Android and iHealth and has been for many years. It's Bluetooth, uses AAA batteries, measures in both lbs and kg with an accuracy of 0.2 lbs (again, calibrates pretty well to my MD's scale). Received over 300 thousand five star reviews on Amazon and there's no love here at all. Why?

The QardioBase X also features a built-in rechargeable battery that lasts up to 12 months on a single charge like the Withings Body Cardio, rather than consumable batteries that need to be replaced after 18 months like the Withings Body and Body+. Plus it's USB-C, like most Apple devices.
