How to Share Purchase Between Family Members
(With Family Sharing, when anyone in the family buys an app, Apple charges the credit card that’s associated with your Family Sharing group. But, before you buy an app, remember that you can download apps that other family members have purchased, with no additional charge.)
2. Finding other people’s apps is a little tricky. On your device, open the App Store app, tap Updates, and tap Purchased. On the Purchased screen, tap a family member’s name to see and download their apps. Developers can exclude their apps from this free sharing option, so if you don’t see an app, that might be why.
