Connecting a smart scale to your health apps
Many smart scales store your readings in their own app. Most also offer to share them with a health platform so your weight and other data sit alongside activity, sleep and other information.
Apple Health on iPhone
When you set up the scale’s app, it will ask for permission to write data to Apple Health. You choose which data types to allow, such as weight or body fat percentage. You can change those permissions later in the Health app’s sharing settings or in your iPhone’s privacy settings.
Android: Health Connect and Google Fit
Google has been moving Android health data from Google Fit to a system called Health Connect, and Google has said that the Google Fit APIs are being retired in 2026. Whether a scale connects through Health Connect, Google Fit or both depends on the manufacturer’s app version and your phone. Check the app listing or the manufacturer’s support page for current compatibility before you rely on a specific option.
If readings do not appear
- Make sure the scale’s app is updated and has Bluetooth permission.
- Check that the health platform permissions are switched on for each data type.
- Open the scale’s app after weighing so it can finish syncing.
- Avoid enabling several apps that write the same data, which can create duplicates.
Think about privacy
Review what each app can read and write, and read its privacy policy. You can revoke access at any time in your phone’s settings.
