As an old DJ who hasnt been in the game since vinyls and (at the most recent) the CDJ500S, this app is seriously lots of fun. If you have the basic DJ skills, you can make some excellent mixes right away. If youre a newcomer, you can still have fun. One thing though, after playing with it for 4 hours nonstop I decided to check out the auto mix feature and… crash over crash over crash. Not great. To be fair, the auto mix is pretty pointless if you can actually play, but I can imagine if youre throwing a party and dont have time, it could be useful. Anyway, auto mix is a crash command. Shame. Apart from that: good job on the app, its pretty much the killer.
