Literally this site needs an app published.
We don’t support that app anymore, and we didn’t really make a replacement one.
This website, the forums, runs on Discourse forum software, and Discourse has their own app for forums that run on Discourse. I’m not sure if it’s good, but you could try it out.
I did and it’s just like using a browser but without a URL bar to enter another website… It will give you the list of forums that you frequently join and that’s it.
