## What is Judo Shiai Scoreboard?

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.

### 1/5 — Pas de mise à jour yuko

*2026-04-26*

Domage

**Developer response:** Bonjour,
Pourriez-vous préciser à quoi vous faites référence exactement (en nous écrivant à support@judoshiaiapp.com) s’il s’agit d’un manque ou d’une erreur?
Le yuko est disponible avec le choix des règles 2025 via les réglages. D’autres paramètres telles que la durée des immobilisations sont également modifiables.

### 5/5 — Mega-App für den Judo-Wettkampf

*2025-03-08, version 2025.32*

Das Neubekleben der Wettkampftafeln gehört der Vergangenheit an. Diese App macht selbst ein kleines Randori zu einem professionellen Event. Die Entwickler haben innerhalb von wenigen Tagen die neuen IJF-Wettkampfregeln 2025 in die App integriert. Unglaublich!! Das Streamen vom Tablet auf ein beliebiges Ausgabegerät (TV,Beamer,etc.) ist kinderleicht. Ein unverzichtbares Gadjet im Dojo! Vielen Dank an die Entwickler für dieses super-nützliche Tool. Euer Bodenfuchs!!

### 5/5 — Super

*2024-06-06*

Super application, toutefois je regrette un peu que pour les scolaires il n’y ait pas au moins les premières lettres des avantages (I pour ipon, W pour wazari et Y pour yuko). Merci 🙏🏼

**Developer response:** Bonjour,
Merci pour retour. Nous avons pris en compte votre demande, et la version 2025.32 permet désormais d’afficher le nom des points. Pour cela, cochez l’option correspondante dans les réglages du tableau de marque. 
Cordialement

*2019-03-21, version 5.0*

As a small club and wanting to hold small events and with the ever changing rules this app is perfect. Download, hook up to a TV/monitor and off you go. Looks good, easy to use, a must for all clubs.

### 5/5 — Closed club competition
