In all fairness, it doesn't have the sexiest UI and has a lot of room for improvement but it definitely does what you download it for. Mixing on it is a breeze and the beat matching features works spot on.
I hope the developers of the app, Beatronik, make a couple of main UI changes, in order to make the console controls, beat bar, and other parts bigger/easier to click. Once those changes take effect, this could be the best DJing app on the PlayBook. Until then though, DJPad will still be #1 in my book.
