Rovio’s Angry Birds Seasons tops the free app charts this week thanks to its temporary status as the free iTunes App of the Week. The app is currently the No. 1 free app on both the iPhone and the iPad.

Lower down the charts, the Budapest-based Goroid Kft’s game The End also puts in solid work, taking the No. 4 spot on the iPhone chart and the No. 3 spot on the iPad chart. The title has similar gameplay to Temple Run, but moves the setting to the end of the world. While the app is free, it monetizes through the purchase of Duct Tape, which serves as in-game premium currency, and a $1.99 option to upgrade to a pro version of the game.

This week’s fastest rising free app is JanduSoft’s Guess the Character!, a simple guessing game that challenges players to identify well-known characters and celebrities by looking at likenesses created with Nintendo Miis. While the game is popular now, it remains to be seen how long it will be able to remain on the app charts before Nintendo notices where the game is pulling its content from. The app rises 26 spots to take the No. 10 position on the free iPhone apps chart.
