Google Play Family Library has rolled out and will allow you to share purchased items between up to five accounts. No more having to duplicate a purchase on the SO’s phone so that Super Robot Kitty Princess 3000 will be near when the little one needs her.
To sign up for Google Family you’ll need to designate the head of the Google Family Library. It seems a little hierarchical that there can be only one, but true to Highlander rules, there can be only one.
You can choose at signup to share everything, or add items as you want. To remove items you don’t want shared if you chose to share all (EG Super Sexy Space Vixens,) you can simply go to the app’s details page in Google Play and remove it there.
To sign up, simply open the Play Store on your Android device and there should be an introduction to Google Play Family Library right there. I’m assuming they’ll change that in the future, but for now it’s front and center.
