Giggity Scheduling and Calendars app for Android description
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.
