You can check which devices and apps update specific health categories and choose the sources Apple Health uses first. Here's what you need to do:
- Open the Apple Health app on your iPhone.
- Tap a category (steps, activity, active energy).
- Scroll down, then tap Data Sources & Access. Only the sources that contribute to that data type will appear.
- Tap Edit.
- Touch and hold the Change Order button next to a data source, then drag it up or down in the list.
- Select the check mark at the top right.
Sync Changes: Open the Sonic Boom app on your iPhone to sync the changes.
