You’re going to want to delete apps. Whether it’s an Android smartphone or a Windows PC, at some point apps start cluttering your machine and need to be deleted. This is a relatively simple process on all platforms but sometimes it can be difficult to find for new users. None of these platforms make it explicitly clear how to delete apps when you buy a new device, which is why articles like this one have to be written.
On your home screen, tap and hold any app icon until it begins shaking or wiggling. All apps on your screen will be wiggling and an X will appear to the top left of the icons. Tap that X on the app you want to delete. Now tap the red Delete button. This will delete the app from your iPhone. Go to Settings > General > iPhone Storage. Scroll down and you will see the list of all apps installed on your phone, with the apps taking the largest size showing up on top. Tap on the name of the app you want to uninstall. Tap Delete App on the next screen and again tap on Delete App to confirm and delete the app.
