SCOREBOARD • Full judo scoreboard: ippon, waza-ari and shido, with the match clock and golden score handled for you. • A separate osaekomi timer, with hold durations you can adjust. • 2025, 2018, 2017, 2013 and 2010 rules, so you score the way you want. • Custom fight durations, from a school tournament to an international contest. • Team match mode for club and interclub competitions. • Four display themes, from IJF competition style to a high-contrast dark board.

EXTERNAL SCREEN • Connect your device to a TV with a cable, or use AirPlay, for a full-screen scoreboard. • The board adapts to the screen it lands on, while the controls stay on your device.

SYSTEM INTEGRATION • A Live Activity keeps the score and the clock on your Lock Screen and in the Dynamic Island. • Siri and Shortcuts start, pause and stop a match or a randori for you.

RANDORI • Interval countdowns for practice: set the work and rest times once, then keep your eyes on the judoka.
