## Description

Everything you need to referee a judo match on your device, with a full-featured scoreboard displayed to any TV.
Try it for free, go Premium to unlock all limitations!

Judo Shiai turns your iPhone or iPad into a full judo scoreboard, and mirrors it to any TV or external screen so the whole mat can follow the contest.
Whether in competition or in practice, Judo Shiai will quickly become your best companion on tatami.

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.
