KonOpas is a mobile-friendly guide for conventions, with all sorts of spiffy features. It’s free, open-source software distributed under the terms of the ISC license.
The latest release is 0.8.0, which adds second-level items to the “Programme” and “People” menus, as well as hiding past events by default when viewed during the event. Other relatively recent features have included access to a central server that allows sync’ing data between different browsers and devices, full internationalization support, and automatic filter generators.
