I wanted to share a tool my team and I have been working on! It is called RefHQ, and is a mobile app designed to help basketball referees learn, study and master basketball rules.
The app has >550 multiple choice and True/False questions written to key in on the details of the rulebook and casebook, with more questions added each month. Users can specifically study one of the 11 rules at a time, shuffle all questions, or choose a category such as the 2019-2020 Rule Changes.
The app is currently supported on iOS, and released for the NCAA-M ruleset. Android support, as well as support for other rulesets, will be coming in the future.
