You mean a Bitcointalk app? Yeah no, that's not happening , an unofficial one exists, but that's no good. And the administration isn't much interested in it.
I really mean responsive not actually Android app.
if it's responsive there is no need to even download app unless you want notifications, even notifications can be integrated in browser.
why there's no support for Android Devices for this forum to make it responsive?
That issue already has a solution but you'll have to wait until the new forum is introduced/finished (they'll be using "epochtalk" [it's responsive]):
Epochtalk is already responsive for mobile. We will also think about a native implementation if there is enough public demand.
While the frontend design is not yet complete, Epochtalk was made to be responsive and mobile friendly (unlike SMF 1.x). You can expect further improvements in the UX down the road once it gets a higher priority.
New threads don't appear as the current data on the Beta is from October 2016. New data has to be migrated from Bitcointalk for new threads to 'appear' on the Beta.
or maybe a responsive theme ... would solve it, I wasn't aware of Epochtalk software, but I know Vanilla Forums, Open Source and free forums software, it can be responsive as well.
the thing is you want to take bitcointalk with you on the go so you reply thread and everything while you are away...
