The app renders the schedule in the default locale, which right now (for me) is the US. So, the lectures start at 2am in the morning :) Set the locale to Germany, and that should fix it.
Thanks for fixing the agenda issues. It will be nice to have the location of the talks for the next edition.
Finally, I participated in a conference without checking the plan on paper! Plan and paper all available on mobile! That was a great experience!
Worked well for the purpose of finding the events.
