Kata Calc vs Taikai App

Kata Calc is an iPhone application to caluculate WKF (World Karate Federation) Karate Kata Competition in old rule (point system).

Taikai is the companion app for karate tournament day — built for the families, coaches, officials, and directors who live the six hours around four minutes of competing. KNOW THE MOMENT THEY COMPETE Open the app on tournament day and see exactly what matters: your athlete's next division, their mat number, and an estimated start time — updated live as the event runs. Get a push the moment they're called, so you're never stuck in the wrong ring or missing the one match you came to see. ONE TAP TO EVERYTHING • Digital check-in badge — a scannable QR you show at the door, always in your pocket • Live results and placements as they're posted • Watch live scores from any ring in the venue • A running feed of alerts: match calls, results, approvals, and schedule changes, each timestamped FOR THE WHOLE FAMILY AND TEAM Following more than one competitor? Page between every athlete on your account. Coaches get a team view — all of your dojo's athletes, all their mats, and who's up next across the whole team, on one screen. RUN YOUR DOJO Create your dojo, manage your roster and members, and approve join requests — right from your phone. FOR OFFICIALS, STAFF, AND DIRECTORS Judges, coaches, and staff carry their own event credentials and check-in badges. Directors approve role requests on the spot and use the built-in check-in scanner to badge in competitors and staff by camera — no laptop required. FIND YOUR NEXT TOURNAMENT Browse the karate tournament directory, see full event details, and jump to registration on the web when you're ready. Registration and payment are handled on taikaiapp.com so your account works the same everywhere. Taikai is made for karate — kata and kumite, WKF and AAU formats.
