You can delete an app from your iPhone in two ways: in iTunes on your computer or directly from your iPhone. To delete an app in iTunes, click Apps in the source list and then click the app’s icon to select it and then choose Edit→Delete or right-click (or Control-click on a Mac) the app’s icon and choose Delete.
For example, if you are trying to delete an app called 'LEMON,' you would enter the following command: sqlite3 /Library/Application Support/Dock/.db 'DELETE from apps WHERE title='LEMON';' && killall Dock. You can find the exact name of the App by going to the Applications folder and searching for it. Sometimes, though, they still don't work the way iOS apps do. For example, if you want to delete an app, but it doesn't have an X when you trigger jiggle mode, or when you try to delete it old-school style in Finder, you get a message that reads, 'The item 'app name' can't be moved to the trash because it's open.'
Either way, you see a dialog asking whether you’re sure you want to remove the selected app. If you click the Remove button, the app is removed from your iTunes library, as well as from any iOS device that syncs with your iTunes library.
How to delete an app on the iPhone
While deleting an application via iTunes on your computer is a great method, you’re not always by an iTunes accessible computer. No worries – you can uninstall or remove any apps directly on your mobile phone. Here’s how to delete any third-party app on your iPhone:
1Press and hold down any icon until all the icons begin to jiggle.
How To Uninstall Apps On Mac
You can’t delete any Apple apps that came with your iPhone (for example – Messages, Settings, Clock, and Camera applications cannot be uninstalled or removed).
2Tap the little x in the upper-left corner of the app you want to delete.
A dialog appears, informing you that deleting this app also deletes all its data.
3Tap the Delete button.
Deleting an app from your iPhone this way doesn’t get rid of it permanently. The app remains in your iTunes library until you delete it from iTunes. Put another way: Even though you deleted the app from your iPhone, it’s still in your iTunes library.
How Do I Delete App From Mac
If you want to get rid of an app for good and for always after you delete it on your iPhone, you must delete it also from your iTunes library. Even then it’s not really gone forever because you can download purchased apps again for free.
