c3nav

c3nav is an Android application for indoor navigation at the Chaos Communication Congress. It is intended for use inside the event venue, where ordinary street maps do not describe rooms, corridors, halls, and other interior locations with enough detail. The app provides a way to find places within the congress site and follow routes between them.

Its scope is tied to the congress environment rather than general outdoor navigation. Users looking for city routing, car navigation, or maps for unrelated buildings should treat it as an event-specific tool. The application is distributed under the Apache-2.0 license.
