I have had a couple of requests now for Tapatalk or something similar on my board. The Tapatalk application does not currently support phpBB2, but iPhone / Android support is becoming more of an interest to folks. Tapatalk is not a template or theme, it’s an application designed to interact with a discussion board (they support phpBB3 as well as several others).
I have to admit that I find this to be a far more intriguing idea than a mobile template. The folks behind Tapatalk offer a free API that would allow developers to extend the app to different forum systems. It would be interesting to see if anyone is currently working on phpBB2.
I’m registering on their “Forum owner” area and will see what things look like.
