Giggity

Giggity loads xcal/Pentabarf/frab XML files (that contain schedules of
conferences/festivals/other events) and lets you browse them in various
convenient formats.

Preseeded with data for FOSDEM, CCC, FrOSCon and other conferences.

Giggity lets you organise your visit - select talks to be reminded of (with
warnings in case of conflicts) or hide the topics you're less interested in.
Schedules are shown in whatever format you like - block schedules, plain
timetables, or a clear now-and-next screen on the day itself.

Or just put a widget on your homescreen which will always show you what's next.
