Following just a few months after its release on the iPad, Native Instruments have unveiled a version of the Traktor DJ app for the iPhone and iPod Touch. It would appear that NI was able to condense a good portion of the functionality found on the iPad app—which you can learn all about in our recent review of the program—into the smaller, mobile-phone package, and at a rather low price point too, just below $5. The Traktor DJ app for iPhone is available now from the iTunes store. A promo video for the new app can be viewed below.
