Nike worked with AKQA to create the True City iPhone App, which is free for download on iTunes starting today. The app, equipped with geo-tagging features and full social media integration, gives users insight to the best parts of six European cities--London, Berlin, Amsterdam, Milan, Paris and Barcelona--through the eyes of local tastemakers. Each city has a group of designated contributors whose M.O. is to "Make the Hidden Invisible" for the app's community. Civilian contributors are also invited to add their own finds, and the best will have the opportunity to become join the team of Nike insiders. The QR-code enabled app also gives users the chance to unlock additional Coded info in each city.
