Tap Tap Revenge 4

Tapulous's fourth entry in the Guitar Hero-inspired Tap Tap series may be their strongest yet. The game has undergone a graphical upgrade, made more noticeable by the heavily stylized layouts of each song. With hundreds of music tracks from a wide variety of artists, Tap Tap Revenge 4 outshines all of its iOS competitors. While the app itself is free, most of the tracks must be purchased through an in-app store. Even though the songs are already reasonably priced, Tapulous also provides many opportunities to earn songs for free. The Tap Tap series has already proven its worth in the past, and this installment is the best one yet.
