Releasing an Educational Android App

This paper explores the process and challenges of creating an educational app for android devices. The Heat Loss Calculator app was initially conceived to allow researchers to quickly calculate building heat loss by entering the U-values of different building element fabrics. Selecting lower U-values equates to the various insulation improvements which can potentially reduce heat loss and improve energy efficiency. During early development it became clear that the app would also be a useful learning tool for students. Therefore, it was designed with this wider audience in mind, with the intention of publishing it in the public domain. Issues encountered during development and some that became apparent after release on the Google Play Store will be discussed. The user experience will be evaluated by means of an online survey of students and by using the app in a group session in the classroom. The feedback will be examined to inform how the app can be improved.
