I'm unsure about if there is anything going on with an app, I will see if I can find out anything for you.
The issue with the chat room is that Java typically does not work or function completely on Android phones and apparently Apple has said that it is not going to provide support for Java-based applications with it's products. I could be wrong as my household is an anti-Apple one thanks to my husband
A google search told me that however, so take that with however many grains of salt you want
In terms of the type of software we use for the chat room, we require software that is compatible with our board software, so that for example, banned members or people who don't even have a Pandy's account can't enter the chat room. So any chat system we choose will need to be able to be fully integrated within the IP Board software and provide maximum ability to be customised and managed by the board moderators and chat moderators. This is why we can't just change to another type of software that may be more accessible on the smart phone platform.
I hope that is of some help. In the meantime, the message board is able to be viewed using a phone of course, and is probably much better for your sanity and your fingers in terms of typing, as the fast pace of the chat room would really put you to the test if you were able to get in with your tablet or smart phone.
