The Apple Design Award winners are in, and they showcase the cutting edge of game and app design.

At a ceremony Monday at the Worldwide Developers Conference, Apple handed out 12 awards to the best apps of the past year. Games scored half of the nods, with some really cool productivity, finance and utility apps also taking honors.

Here are all of this year’s winning apps — and why they won.

I’m a terrible DJ (unless you count success by the number of people you can force off the dance floor with one track, in which case I’m a total mix master), but I’ve worked with enough DJs to know the tricks of the tracks. And one of those tricks is the old left-it-at-home routine.

When somebody requests a song you don’t want to play, you say “Excellent song! I love that one.” Then you pause and say “I think I left it at home.”

Now, Djs will have no excuse, becasue the new Pacemaker app will let you spin and mix tunes from Spotify’s huge gazillion-song library.
