To sync Apple Watch to Weight Watchers, you connect through Apple Health on your iPhone rather than pairing the watch directly with the WW app. This integration lets your Apple Watch activity automatically convert to PersonalPoints™, but you need iOS 16.0 or later on your iPhone and watchOS 9.0 or later on your Apple Watch.
Install the WW app on your Apple Watch
Before syncing can work, the WW app needs to be on your watch. Open the Watch app on your iPhone or iPad, navigate to the My Watch tab, locate the WW app, and select Install. This step is essential for your smartwatch setup and pairing to ensure the watch can later communicate activity data through Apple Health. You can also check blood pressure with Apple watch to build a more complete picture of your overall wellness.
Connect the WW app to Apple Health
This is the core process that enables data sharing. Open the WW app on your iPhone, then tap the person icon (profile icon) in the top right corner. Tap the gear icon (settings icon) in the top right corner, then tap Devices (or Activity Settings then Apple Health, depending on your app version). Tap Apple Health, then tap Connect to Apple Health. On the next screen, tap Turn All Categories On to sync all available data, WW encourages enabling all information for future features, though you can choose to share only steps if preferred.
Set your Apple Watch as the data source
To confirm your watch is the primary source for step data, go to the Health app on your iPhone and tap the Steps graph. Tap Share Data and verify your Apple Watch is listed under Data Sources. When your Apple Watch is connected as a source in Apple Health, the steps from your watch will automatically convert to PersonalPoints™ in the WW app.
Troubleshooting sync issues
If your activity doesn't appear immediately, know that it can occasionally take up to two hours for the WW app to retrieve data from your device. Apple Health data updates every hour from the time you connected to Apple Health. If you don't see your Apple Health steps in your activity log, scroll to the end of the activity log in the mobile app and tap Sync with your Apple Health app, then pull down to refresh or close and reopen the app.
Keep in mind that you can only connect one device or app at a time to ensure accurate activity records with minimal duplication. If you delete and reinstall the WW app, you will be disconnected from Apple Health due to privacy policies and will need to reconnect by following the steps above again.
