RefSignals: A quiz app built using App Inventor - how to stop repeated questions

RefSignals app screenshotSummer is an odd time. With no ice hockey matches to attend our thoughts turn to other subjects, such as why does RefSignals sometimes repeat questions? I've been asked a few times about how to stop it doing this, so here is a solution. RefSignals is an Android app built with Google App Inventor for Android that quizzes you on the signals made by referees during ice hockey matches. In February I wrote about this app and published the source code so that people could take it and use it as the basis for their own quiz apps. The response was great and the app has been remixed for all sorts of subjects so I hope this will come in useful.

I've been going on quite a lot about Google's App Inventor for Android to anybody who will listen recently. An example application I show them is one I built as a result of a conversation I had with my friend Georgina Parsons while we were sat in an ice rink in Gothenburg, Sweden watching a great match between the Frölunda Indians (the local team) and HV71. Ice hockey is a shared interest of ours but normally we attend matches in England so following proceedings in Swedish could be tricky. Fortunately the referees have a series of standard signals they make to indicate which penalties they are calling and our conversation turned to how it would be great to have a mobile app to help us learn those signals.
