When should you download?
If you have an Apple device with a relatively low amount of storage space, such as a 32GB iPad, and still stumbling over the storage limit, downloading apps is a great idea. Automatic download will free up a lot of space. Also, since it only removes unused apps, you probably never notice that those apps are no longer installed.
How to download applications manually
To manually download apps one at a time, open “Settings” and then tap General> iPhone Storage (or General> iPad Storage on an iPad).
There, you will see a list of all installed apps sorted by size. Touch the one you want to download. On the next screen, tap “Download app”.
The application will be downloaded. If you ever need it again, just tap its icon on the home screen and it will download automatically.
How to automatically download unused applications
To activate automatic download, tap “Settings” and then “App Store” (or “iTunes and App Store” on certain versions of iOS and iPadOS). Scroll down and activate “Download unused applications”.
Give your device time to decide which unused apps to download. Depending on the amount you download, the process may take a few minutes or more. When you come back later, you should have plenty of room to breathe to install new applications or work with documents.
