Get Rid of the Apps That Just Aren’t Working

On the other hand, if you’re tired of your apps not working as they should, you can just get rid of them. Of course, this will depend on the type of app you have in mind. For instance, you probably can’t get rid of your bank’s app. But if you have faulty apps or games that can be easily replaced, you should eliminate them.
You can delete them by long-pressing the icon and then selecting Remove App. Next, simply tap Delete App, and your iPhone will remove it completely.
You can then search for alternatives online or directly on the App Store.
