Our DJing best app pick is called: djay, an app designed to turn your portable music player into a full-fledged, music mayhem, disc jockeying machine!

Created by the obviously brilliant team at algoriddim, at $19.99, djay is the most expensive app to date in our “Best 30 Apps For…” series, so I’m here to tell you why it’s well worth the bling.

Although algoriddim’s name is a slightly obnoxious, pun based contraction, of the words algorithm and rhythm, we couldn’t agree with them more. With direct access to your iTunes library, djay will allow you to use your music and your devices powerful OS, to your advantage. With djay, enjoy “pitch bending”, “high-quality scratching”, “automatic beat and tempo matching” and even a full on “Hyper-realistic, low-latency, turntable interface”.

Although  I can go on forever, talking about djay and its ridiculously fun, party making capabilities, the team at algoriddim did a great job doing a short video on the app themselves:

djay can be purchased right here, and I highly recommend that you do!
