If you're looking to access and install apps you've previously purchased, you'll need to go to the Apple App Store. On the home screen, select App Store. If you use Family Sharing, you can select the name of a family member to view their purchases. Find and select the application you want to download again. Once there, tap the “Updates” button located in the lower right corner of the App Store home screen.
Tap the App Store app icon on the home screen of your iPhone. You'll see shortcuts (officially called quick actions), one of which is the Purchased tab. Tap it and then tap My Purchases to access your list of previously downloaded apps. Next, you'll be presented with a complete list of all the apps you've downloaded or purchased with your active Apple ID. If you've already purchased an app and can't find it in the App Store and following the steps above hasn't helped, you might not have any luck. With a relatively simple method through the iOS App Store, you can quickly and easily restore previously purchased apps from several iOS devices.
On iOS 15 and iPadOS 15, you can easily find, search and redownload apps that you've previously purchased from your Apple ID account in the App Store itself. While Apple allows you to redownload most apps, keep in mind that some of them aren't suitable for re-downloading. In addition, apps that Apple removed from the App Store won't even appear in your purchase history to begin with. Basically, thanks to the cloud-based app backup system used by iOS, you can take your apps anywhere in the world, as long as you have access to your Apple ID. To see all the apps you've purchased on iOS 13, you need to go to your iCloud profile, which is visible in the App Store itself. If you can't find the app you're looking for, you might need to sign out of the Apple ID you're currently using and sign in with the Apple ID that you purchased the app or game with. Now that you know how to find your app's purchase history, you'll probably want to download some of your old favorites. Keep in mind that this tab is a bit misleading because it contains both the apps you've purchased and the apps you've downloaded for free.
The ability to re-download purchased apps both on the same device and on different iDevices gives you true flexibility when it comes to managing iOS apps.
