Referee Companion is an extensive guide catering to referees across all Powerlifting levels. It features a range of tools, including:

Easily accessible failure reasons, color-coded to corresponding lights.
In-depth technical specifications for Platform and Lifter equipment.
Comprehensive lists detailing Weight categories and Age restrictions.
Approved Kit lists for both Lifter and Platform equipment.
A Weight Plate calculator that dynamically generates values as you input them.

Finally, there is a comprehensive list of questions covering all aspects of powerlifting, and a minigame that consists of 10 randomly selected questions drawn from any of the categories, or you can choose one specific sub-category to work on. Categories range from International Rules to Technical Spec numbers, right down to The Basics. Solutions to all of these questions can be found in the Question Database menu, from the Question Practice section of the App.
