I saw in the VBForums: Change is coming.... somebody had asked about Tapatalk. Doesn't look like anyone answered it though.
I've been looking at this mobile app myself since so many forum sites support it now.
From their home page:
From their FAQ page:Tapatalk is an award winning app for forums with lot of features. Whether it is the hassle-free photo sharing, instant push notification or advanced features such as discussion Moderation, there are a lot to love Tapatalk.
Any idea whether this or some alternative non-web mobile interface is coming? If so which and when should we expect it?Tapatalk is a mobile app built specifically for forum access. Different from mobile skin or mobile version that comes with the forum system, Tapatalk allows user to have a unified interface to access multiple forums at the same time. With million of Tapatalk users, your forum can be discovered by potential new members through Tapatalk Network and our ranking and recommendation system.
It looks like the app comes in flavors for BlackBerry, iPhone, iPad, Android Phone, and Android Tablet. Pretty broad coverage, and if WinPhone ever becomes stable and achieves above 3% market share it might get support as well.
