Tap DJ is a comprehensive multimedia application designed for iPhone and iPod users who want to bring their DJ skills to the next level. This app allows users to scratch, mix, and add effects to their favorite tracks, making it suitable for both novice and professional DJs. With access to an integrated iTunes library, users can easily load their preferred songs or select from the preloaded sample library. Key features include a 3-band equalizer for each deck, a 9-pad sampler, and the ability to record mixes and voiceovers.

The app stands out with its innovative GyroScratch technology and offers a stunning turntable interface with live waveform views, enhancing the mixing experience. Tap DJ also supports importing tracks via USB, WiFi, or from the iPod, and provides three loopable cue points per deck, allowing for precise control over mixes. With features typically found in much more expensive desktop DJ software, Tap DJ is an excellent tool for music enthusiasts.
