While sharing an Apple ID for purchases can be useful, it can cause issues like this one when it comes to personal data. The Apple Watch and the Fitness app are designed to work with individual Apple IDs, and that’s why your data is showing up on your wife’s phone.
One way to fix this is to set up Family Sharing. This will allow you to share purchases and subscriptions, while keeping other data, such as health and activity data, separate. Here are the steps to set up Family Sharing:
1. On one of your iPhones, go to Settings > [your name].
2. Tap Set Up Family Sharing, then tap Get Started.
3. Follow the onscreen instructions to set up your family and invite your wife to join.
Once Family Sharing is set up, your wife should create her own Apple ID and sign in to her devices with that ID. You can then invite her to join your family. This way, you can share purchases and subscriptions, but your Health and Activity data will remain separate.
Remember to unpair and then re-pair your Apple Watches with your respective iPhones after setting up separate Apple IDs. This ensures that each Apple Watch is associated with the correct Apple ID and iPhone.
It’s important to note that any data that has already synced with the wrong Apple ID may need to be manually deleted.
Always remember to backup your devices before making any significant changes to avoid any potential data loss.
