How to delete Watch app after no longer owning Apple Watch

You cannot delete the Apple Watch app from an iPhone. The Watch app is a built-in (system) app in iOS, so Apple does not allow it to be removed — even if you no longer own an Apple Watch.

Since it cannot be deleted, you can remove it from view:

Option A – Remove from Home Screen

1. Long-press the Watch app icon
2. Tap Remove App
3. Select Remove from Home Screen (not Delete)

This moves it to the App Library only.

Option B – Move to App Library Folder

You can drag it into a less-used folder or leave it in App Library so it’s out of sight.

The Watch app is a built-in Apple app.

In most cases, you cannot permanently delete it, only remove it from Home Screen.

Make sure your old Apple Watch is removed from your Apple ID devices list.

I disagree, you can delete it in the usual way, tap and hold, tap Remove app, then tap delete app.
