Forget the turntable—it's time to pump up the volume on your iPad. Native Instruments' new iPad-only DJ software, Traktor DJ, brings a portable interface to professionals and newbies alike. The easy-to-use app even aggregates music straight from your iTunes music library.
We've seen (and failed at using) a lot of the terrible DJ apps currently available, but this one has an interface that makes sense.
Platforms: iOS (iPad only)
Pros: The app suggests songs to mix straight from the iTunes library if you need inspiration for which tunes are most mashable.
Cons: We like the ability to change the tempo by circling our finger around like we're spinning an actual record, but the placement of this part of the interface makes it difficult to adjust the tempo of both songs simultaneously.
