Are you running low on space on your iPhone or iPad and you are you using iOS 11? Apple has added a quick way to free up storage space by removing unneeded apps making this problem easier to deal with than you may think. All you need to do is go to Settings > General > iPhone/iPad Storage. You’ll see a Recommendations section. This section may include an option to Offload Unused Apps with an estimate of how much space you could save. Now just tap Enable to allow iOS to remove apps that you haven’t launched in a while—this happens only if you’re low on space.
The good news is your iPhone or iPad will preserve any documents or data associated with the offloaded app. This way if you re-download the app, you will still have all your documents and data for the app. How do you re-download it? Well when an app is offloaded, the app’s icon still remains on the Home screen, but you’ll see it with a cloud badge. Tapping the app icon reloads it from the App Store, assuming it’s still available. If you find yourself waiting for apps to reload often and you can clear space in other ways, you can disable the feature in Settings > iTunes & App Store > Offload Unused Apps.
