BFS gives us three gems per day to give to others (they don't serve you at all and you are not giving from your own stock). After you purchase the Dragonsai Gifting Tree you can give 6 per day.

There is more information on the Gems page. For Android, you use Facebook and yes, an Apple user can be your friend by being a FB friend.
