Daniel,
I think Steven is talking about expanding and copying the info from the agenda online Agenda | 2015 Esri User Conference I decided to do the same (copy and paste to a .doc file) until the planning feature is released online and/or the apps.
the iOS version of the app had an upgrade available on June 26 that allowed you to login with your global account. However, the UC2015 is not appearing on the conference list yet (as of June 29 a.m) but I think that is just a matter of it being released (my guess).
Re: not being able to log in: I don't have an android device, but I would check to see if the upgrade is available yet in that store. If you have the upgrade installed, make sure you are using the account you use for the UC (global) and not your arcgis online, in case they are different.
