How to Transfer iPhone Apps to another iPhone
It’s quite easy to transfer apps from an old iPhone to a new one or to share apps with your iPhone family. However, you have to use the same Apple ID as the one on your last iPhone. Activate “Family Sharing” in “Settings” to share apps with family members. You can add up to 5 family members with your account. Sharing apps with those who aren’t family members is a violation of Apple’s Terms and Conditions.
Setting Up a New iPhone
Anything you download from the App Store, iTunes, or iBooks is linked to your Apple ID. This means if you change your device, you can download the same apps again, free of charge. When asked to enter an Apple ID while setting up a new iPhone, enter the same Apple ID as the one on your last iPhone.
When you open the App Store, click on “Updates” and then “Purchased” to find your old apps.
If you synced the apps on your old iPhone using iTunes, then you can also sync your new iPhone to iTunes to transfer those apps. Backups using your Apple ID are also interchangeable. You can use those backups when setting up your new iPhone.
Resetting an iPhone
If you created a new Apple ID on a new iPhone, reset and erase the settings. Backup your files to your computer.
Open “Settings”<“General”<“Reset”<“Erase all Content and Settings.”
When the iPhone restarts, enter an Apple ID. Use your old Apple ID from your last iPhone. Now, you’ll be able to access your purchased apps, iTunes, and iBooks content.
Changing Your App Store Account
One option is to reset an iPhone. Another option is to sign out of both iTunes and the App Store. Then, sign in again with your old iPhone’s Apple ID.
One issue, however, is that Apple makes you wait 90 days before you can change from one Apple ID to another. Open “Settings,” select “iTunes & App Store,” then click on your current Apple ID and select “Sign Out.” Enter your old iPhone’s Apple ID.
Verify your credit card information. Now, you should have access to the purchased apps on your old iPhone.
Sharing Apps With Family
Apple’s Family Sharing feature, allows an adult to share apps, iTunes, and iBooks content, with up to five family members.
Open “Settings” on your iPhone, select “iCloud,” then “Set Up Family Sharing.” When asked to do so, you can send an invitation to that family member. If they have iOS 8, they’ll receive the invitation through iCloud on their iPhone. After accepting the invitation, your purchases will be visible on the Purchased screen of that person’s App Store.
Not all apps are shareable. It depends if the developer has enabled Family Sharing. Anyone you share your apps with is linked with your Apple ID. Any app or iTunes content they purchase will be billed to your credit card. If your family members purchased any app or content before you enabled Family Sharing, it will also be available on your iPhone.
