Thanks for the recommendation! Using it now, works great. Do you know whether development ia continued anywhere? It doesn’t look to have been updated in many years, but F-Droid doesn’t mark it as unmaintained.

Something I can use to browse GitHub repositories, reply to and create issues, and get notifications for issues on my own repos.

Do you mean Obtainium? I use it to download apps not available on F-Droid, but I can’t use it to actually browse/use GitHub. I will clarify in my OP :)
