I presented to the OKCTUG recently & shared my experience in creating my first mobile-friendly dashboard that functions well with the new iphone app. LOVE the tableau app, by the way. I actually find it easier to navigate over tableau server on the web.
I had full intention of recording the presentation but technology was not my friend that day, so I've re-created a very condensed version (attached). I hope this is helpful and helps spurs some ideas for you!
