By Turning on automatic app updates, you will not have to manually update the app once a new version of the app is released.
To set your iOS device to automatically update its installed apps, follow these steps:
1. Tap the Settings app icon on your Home Screen.
2. In the Settings app, tap your name at the top of the menu.
3. Scroll Down on the Apple ID screen until you see the "iTunes & App Store" menu item and tap it.
4. On the iTunes & App Store screen, tap the "Updates" toggle switch in the "AUTOMATIC DOWNLOADS" section. It will turn green when it is toggled to "On."
All of your iOS apps will now be automatically updated whenever an update hits the App Store.
