djay is on sale for 99¢.
Easily the best one out, and I'm pretty critical of these apps.
The cue points, effects engine, all pretty good, and I also read there's midi capabilities?? for $1?? SOLD.
I actually used it at this local spot last night for fun. Cats i know (music cats too) were kinda blown away. Bar manager bought it on the spot on his phone. lol.
