Organize your apps
Touch and hold any app on the screen until they all jiggle.
Now you can drag any app to another spot, including the Dock at the bottom of the screen.
Press the Home button to save. Or on an iPhone X, press Done.
If you press firmly, then instead of jiggling, you might see Quick Actions for the app. Tap outside of the Quick Actions list, then touch and hold the app lightly to try again.
Put apps in a folder
If you have a lot of apps, you can put your related apps in folders.
To make a folder, drag an app onto another app.
If you want to rename the folder, tap the name field or and then enter the new name.
Now that you have a folder, you can drag apps into it. Folders can have more than one page.
Move an app to a different page
You start with one page of apps. To make a new page, drag an app to the right edge of the screen. You might need to wait a second for the new page to appear. To delete a page, consolidate all your apps to another Home screen. When there are no apps present the page will delete.
When you have more than one page, a bright dot in a row of dots above the Dock shows you which page you're on. You can move an app to a different page and create new pages:
If there are dots to the left or right of the bright dot, you can drag an app to the right side of the screen to move the app to the next page in that direction. Or swipe left to see the apps on that page.
If there are no dots to the right of the bright dot, dragging an app to that side of the screen makes a new page.
