Tap DJ is the ultimate pocket DJ app for iPhone and iPod! Scratch, Mix, and add FX to your iPod music! Load up your favorite track, or choose from the preloaded sample library. Then get DJ-ing!
An uber slick app with very responsive controls. The best “impress-your-friends” feature is the ability to scratch by means of rotating the iPhone – a bit awkward to do with your hands, but you’ll see the application in the video below:
Not exactly something a club DJ would use, but fun to impress your friends nonetheless.
