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 ### 5/5 — Super *2022-12-10, version 2021.1* Super apps! ### 5/5 — Tolle App *2022-12-08, version 2021.1* Leicht zu bedienen. Sehr schön auch die Einstellmöglichkeiten unterschiedlicher Wettkampfregeln. Perfekte Ausgabe auf einen Bildschirm. ### 4/5 — Tolle App *2019-12-02, version 2019.3* Funktioniert auf iPad und iPhone super mit, Bildschirm noch nicht ausprobiert. ### 5/5 — Excellent *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 *2019-03-08, version 4.0* We use this app at our club competition we linked it to a small tv it was easy to understand by the referees and the parents and very easy for the table to use. ### 4/5 — Score board *2017-12-11, version 2.1* Great app but sound doesn't work in Shiai mode ### 5/5 — Génial *2017-09-28* Bonne petite application aussi bien pour les animations que l’entraînement. De petites améliorations côté sonnerie pour mieux entendre. Mais dans l’ensemble à utiliser. ## Frequently asked questions about Judo Shiai ### What is Judo Shiai?
