How to temporarily remove apps

How to check the storage on your iPhone and iPad - Apple Support

"Use your device to check its storage

Go to Settings > General > [Device] Storage. You might see a list of recommendations for optimizing your device's storage, followed by a list of installed apps and the amount of storage each one uses.

Tap an app's name for more information about its storage. Cached data and temporary data might not be counted as usage.

In the detailed view you can:

Offload the app, which frees up storage used by the app, but keeps its documents and data.

Delete the app, which removes the app and its related data.

Depending on the app, you might be able to delete some of its documents and data."

Unless you have a huge number of apps you may not find that offloading apps saves all that much space when compared to the data space they use. You can delete that data but then if you ever want it again you have to make a backup first. I had an app that itself was taking up 0.25 GB of storage but its data files were taking up 35GB.

Press on them until a on screen menu appears and select Remove App and if a second menu appears select Delete App.

Just a warning that some apps might not be available after you update to iOS 26. You should go to the app store to make sure that they will.
