Delete mindfulness from fitness app

Hello susanfromchicago33,

Thank you for reaching out to Apple Support Communities.

You can attempt to delete the data or prioritize data sources using these steps:

"View your data sources

Here's how to see which devices and apps update specific health categories:

1. Open the Health app and tap the Browse tab. 
2. Tap a category, like Activity. If you don't see the category, swipe down to reveal the search bar, then enter a category.
3. Tap a subcategory, like Steps.
4. Scroll down, then tap Data Sources & Access. Only the sources that contribute to that data type will appear. 

Here's how to see all of your sources for the Health app:

1. Open the Health app. 
2. Tap your profile picture in the upper-right corner . 
3. Scroll down to Privacy, then tap Apps or Devices.

Prioritize data sources

Here's how to choose the sources that Health uses first:

1. Open the Health app, then tap the Browse tab.
2. Tap a category, then tap a subcategory.
3. Scroll down, then tap Data Sources & Access.
4. Tap Edit.
5. Touch and hold the Change Order button  next to a data source, then drag it up or down in the list. 
6. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark next to the source.
7. Tap Done.

If multiple sources contribute the same data type, then the data source at the top will take priority over other sources. Any new apps or devices that you add go to the top of the list automatically, above your iPhone or iPod touch. "

If the issue persists, can you provide a few more details? What happens when you attempt to remove or prioritize data source? Also, what is your exact watchOS and iOS versions?

Cheers!
