Apple offers you free apps every day for 12 days
Woohoo! My true love can save the partridge and give me 12 free apps for Christmas!
Apple started offering a free app called iTunes 12 Days Present. With the application, you can download free items including iPhone apps, books, movies, and songs through iTunes for 12 days starting December 26.
Every day, new presents will be sent to you and they can be downloaded within 24 hours (by midnight, Japan time). There are over 100MB worth of contents included in the presents, so Apple recommends that you have a Wi-Fi environment. And you should have iOS 7.0 or later.
