Building an APP with students: The joys and lessons

On January 23rd, 2013, the Avila College APP Group's APP, Lock Spin, went live on the App Store. A few days earlier, it had been available from Google Play. In this post, I reflect on some of the lessons I drew from this experience.
The idea behind Lock Spin was to help incoming year 7s learn how to use their combination locks. It also turned a familiar item at school into something we could have fun with.

Before I go any further, these are the links for downloading the APP:
