Ace Referee is a companion app for handball, racquetball, squash and now RoundNet/SpikeBall referees. It can be used in stand-alone mode or in conjunction with the Bracket Ace tournament app. Ace Referee eliminates the referee's need for pencil and paper. It keeps track of score, server and timeouts on your iPhone, iPad or the Apple Watch.

The Apple Watch version allows you to score a game locally or take over a match from the iPhone. All referee features available in the iOS version including the live scoring feature.

Ace Referee's live score feature allows spectators to view real-time score updates for any match where the referee is using the app. Via the view scores screen users can simultaneously monitor match scores on both the iPhone and iPad. When Ace Referee is used in conjunction with the Bracket Ace tournament app, all ongoing tournament match scores can be displayed simultaneously, users can jump to the event in the Bracket Ace app, and live video or other media can be displayed when made available by the tournament hosts.

Ace Referee can be launched by other apps such as Bracket Ace so that the match data is populated automatically for the referee.

Ace Referee can also scan a barcode on a Bracket Ace scorecard. All match data will be populated and the match result will be reported to Bracket Ace.
