Apple has realized their 12 Days of Gifts app. Starting December 26 through February 6, Apple will be gifting apps, books, movies and songs through the app. Think of it as 12 gifts from Apple over the holidays.
To take advantage of this, simply install the app on your iPhone or iPad. Be sure to enable push notifications when you open the app so you get alerts to the gifts.
You can install the app now via this link.
