Ninja Hoodie: Kotaku says, "The hook with Ninja Hoodie is that it never feels too static, even though it is an on-rails shooting gallery. You never know where enemies will pop up from and successful progression is as much as about reaction time as it is anticipation. You don't get the thrill of creeping up on a bad guy in Ninja Hoodie but throwing shurikens with reckless abandon proves to be its own reward." $1

Compass Eye: If you're a sailor, or just someone that really likes setting a bearing and cursing up a storm, Compass Eye could be your nautical app of choice. Or you could just use an actual compass and the stars. Your choice. $5
