It's clean, it works, the branding makes a bit of a difference. If you like the normal tapatalk then you'll like the branded version. Just looks that bit better for your forum when it's got the splash screen etc.
My current app is forumrunner (branded) from old version, before it was sold to IB, so I paid around 550$ to build it and nothing after that, so now moving to XF I don't know what to do. My app gets 25.000 visits per month, so it's a considerable amount of people using it.
