iCloud allows you to back up your iPhone 8 Plus apps
A Wi-Fi connection is required to create an iCloud backup. As a result, double-check that Wi-Fi is turned on and that your device is connected to the Internet. After you've confirmed that your device is connected, follow these steps:
- Go to the main menu and select 'Home.'
- Go to the Settings tab.
- Sign in with your Apple ID if asked.
- To continue, tap iCloud.
- Select the applications you wish to back up by sliding the slider next to them.
- To get to the bottom of the list, scroll down and then tap the iCloud Backup app.
- If disabled, tap the iCloud Backup option to enable it.
- Tap Back Up Now to start backing up the selected apps.
Wait until the backup is finished. Your apps will then be available on iCloud.
