You've probably seen this: Tableau Mobile | Tableau Software but it doesn't say much about the service. But then I remembered seeing something in the Admin guide: http://onlinehelp.tableau.com/current/server/en-us/help.htm#whatsnew_mobile.htm?Highlight=mobile. Sadly the app they're referencing isn't updated in the Google Play Store or is limited by devices. I have some Apple users, both phone and tablet, but those users tend to use their device's browser rather than the app.
From the webinar a week or so ago, Tableau's looking to add more native device integration to Desktop and Server in an upcoming version. Maybe what you're looking for will be there.
Yes I saw the admin guide, let me check that and get back with my questions.
We've moved the mobile admin topics to a new Tableau Mobile Deployment Guide, which covers security, customization, and more. Check it out here:
