I know, the beam team is really busy making awesome content, but it would be AWESOME if you made a forum app for mobile devices That’s all...
On IOS you can just "add to home screen" for the forum page. If they made mobile support for the forum better (make buttons further/bigger or something so accidental clicking is more difficult to do) it would be virtually the same result
I use my phone rather often to just check the forums through Google, and it works very well already. I don't see much point in this, to be honest.
