Image Line has expanded their iOS offerings, from the poorly received FL Studio Mobile, to include a Mobile version of Deckadance. Deckadance is a DJing application for PC/Mac, which is completely over-shadowed by Traktor and Serato, but once again Image Line beats their competition to the iOS App Store!
There is no information available about what is going on in the Mobile version, and they haven't even updated their website for it yet. It looks like there is only a single Cue point and the limited iTunes description mentions effects and looping. Correction: Eagle-eyed reader Jgordon pointed out the last image on iTunes shows 4 cue points per track nested in the center-menu.
I did find a video from DJ Tech Pro that demonstrates their DJ For All controller scratching in Deckadance Mobile.
