Q: How do I delete apps from my iPhone but keep them on my iPad?

When you delete apps from one device, it never will be deleted from another device.

You can then delte the app from your iPhone and it will remain on your iPad.

Yours

DELETING APPS

1)  Settings>General>Usage>Storage>Delete App

2)  Touch the app and hold your finger down until all the apps start to jiggle. You will see a circled "x" in the upper left corner. Tap it to delete an app. When done press the Home button.

You cannot delete any pre-installed iOS app.

If there is No 'X' on any apps you have Downloaded... then check in Restrictions...

And...

1. Sign in with the Apple ID that you used for the original purchase. See which Apple ID you used to download an item.

2) See if the content is available for redownload. Previously purchased items might not be available if they're no longer on the iTunes Store.

Note:

Anything Downloaded with a Particular Apple ID is tied to that Apple ID and Cannot be Merged or Transferred to a Different Apple ID
