The Adult Swim App is a completely free app compatible with your iPhone, iPad or iPod Touch. What's really radical about it is that you can stream full episodes of your favorite Adult Swim cartoons all without paying a cent.
Robot Chicken, The Boondocks, Aqua Teen Hunger Force and Family Guy are some shows you can watch with the Adult Swim App. It also contains a TV guide that lets you know the schedule playing on your television. One of the more surprising features is the Adult Swim calculator that is included -- not quite sure how it ties in, but it's free!
