Create Your Own Apple Id. Click sign in, then click create apple id. To start, open the settings app and then tap on your name at the top of the screen.

Once you create your apple id and sign in, you can use it for any apple account or service, including purchases associated with your apple id and icloud account. Next, tap “family sharing” to enter the screen where you can manage all of the accounts associated with a parent’s apple id. If you can't see this option, make sure you're signed out of icloud.
No more cutting photos to size and pasting them into your card!
Like the idea i think what your going with the whole idea of making your own app is a real good idea but i think there was info to help learn about the app would be helpful, but also what i think this should focus more on is not only giving people the opportunity to create their app but actually interact with the user more such as letting create and come up with ideas for free but then charge. Although inconvenient due to your spouse needing to set up their settings again, with a few extra taps into the settings, you can log them off the device and create your own account. Upload your own images through the uploads tab and choosing from any jpg, png or svg file in your computer. This article is not for you.
