Family Sharing on Your iPhone with iOS 9
While in iCloud settings, consider setting up Family Sharing on your iPhone. Up to six members of your family — adults and kids — can partake. One grown-up must take on the role of family organizer. It might as well be you. That means you’ll be the person presenting your iCloud Apple ID username and password, and the one on the hook to pay for iTunes, iBooks, and App Store purchases.
As the family organizer, you can turn on Ask to Buy so that you can approve (or deny) any purchase or download requests from other members of your clan.
When Family Sharing has been implemented, you can all share a calendar, photos, reminders, and your respective locations. Family Sharing may also help find a missing device through Find My iPhone.
Should you leave Family Sharing, your account is removed from the group and you can no longer share content with everybody else. You won’t be able to use DRM-protected music, movies, TV shows, books, or apps that another member purchased. And you won’t be able to access the family calendar, reminders, or photos.
Family Sharing works with iOS 8 and iOS 9 devices, OS X Yosemite and OS X El Capitan, and Find My Friends 3.0, Find My iPhone 3.1, and iCloud for Windows 4.0.
