I installed the App, lynced it with my schedule, so far it looks like it will work for me (IOS).  (Actually came in very handy, was out at the lake in a no service area and had some time to relax and go through and really read all the session information.)  Only thing I would really like to see is a map!  I may have read somewhere that maps would be added shortly don't recall or mayabe that was just a map for the expo area.
