No - I will get this if I can get a mobile app. Guess what, now the entire tapatalk forum is down. They have not answered my emails in weeks which is why I want to switch. I have contacted forum runner as well today.
The official Xenforo approach to mobile is to make the site responsive to different browser sizes. Simply resize your web browser to see how it looks in "mobile" format.
This works really well for a lot of people but some people prefer an app. Slavik (a mod on here) is currently looking into developing an app (much like tapatalk or forumrunner) but it's still really preliminary and would not be anything official.
So it sounds like you already have a copy of XenForo running? Sounds very much like a pirated copy - which I wouldn't trust since you don't know what other code is buried in there (exploits ring a bell).
Not to mention it's not kosher coming on the XenForo site and asking for answers to questions and then implying you are running a pirated copy.
