A KMP (Android/JVM/Web) client + Node.js backend that tracks controlled grappling time in the Rdojo Kombat sport. See rdojo.com/kombat for more information.
This app enables multiple judges to vote in real time on which competitor has control during a match. "Control time" only accumulates when enough judges agree — a single biased judge can't skew the result.
- Node.js (v22+)
- JDK 21+
- Android SDK (for Android builds)
