I just picked up the Traktor app for my iPad. Most of my mixes are done in Ableton, but this looked like fun and it's portable, so I decided to give it a try. Although it obviously doesn't offer all the options of Ableton, it does a good job of covering the basics and has some nice FX options. I might have gone a bit overboard with them, but I was really just messing around. It's not something I'd want to use to play live at a party, but it's certainly worth the $20 for a quality DJ app that actually works and is capable of producing decent mixes without train wrecks or constantly searching for a track that actually will beat match correctly.
