Hearts upon Hearts!
This app has a wonderful live wallpaper that will have your friends jealous if they don't have an Android.
This game takes a lot of patience and especially a steady hand as you attempt to build the tallest building you can, and then try beating your score again and again until you throw your phone out the window from sheer frustration.
This app has the highest quality movies to watch, and if you're willing to pay the monthly fee. it's worth it. And the longer amount of time you pay for the cheaper the price!
