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)

Environment variables:

The client supports Android, JVM desktop, and browser (Kotlin/Wasm).

cd app
