Installation was quick and easy, however, you will need your email address and registration confirmation number to initially log on.
The first screen or 'home page' you'll see is the Discover screen and it pictorially bookmarks things from the"Tableau Conference 2015" main menu, which is located in the upper left edge of the screen. Click it and you'll get everything:
What I liked is the Schedule, where you can set up a filter to help find various things and tap the star to mark it as a Favorite (which will show up in the My Favorites as shown in the main menu above):
One other cool feature is the Search option. Tapping the magnifying glass allows you to search for multiple things as you type, much like the search feature on Tableau Server:
However, I found you need to first search for something, anything, and then the active search-as-you-type mode will appear.
I definitely recommend getting the app. I can see it being more helpful for me as everything I need -- contacts, maps, and schedule -- is in one easy to use interface
It indeed is a nice app, very useful and very handy especially when you are going to be running around from sessions to sessions. I still need to build my schedule though. I built a part of my schedule with the web data connector but I guess I like the app better.
