Best Kept Secret is a three day festival, that’s held yearly in Hilvarenbeek, The Netherlands. In 2013 and 2014 the festival drew 15.000 visitors each day. With my company AppFellas, I created the Best Kept Secret festival apps. Using this app, the visitor is enabled to prepare for the festival in a perfect way. The main challenge was: make an app that users can use not only during the festival itself, but also before and after.
