For more information and updates but their Codeberg page can be found here. You can also find downloads of the latest version there. I think they mentioned trying to get it on F-Droid at some point like Infinity is.
You can patch some reddit apps like Sync and use your own api key. Even if you don't browse reddit, it's nice to be able to open the occasional link in a pleasing UI.
Some apps taking serious steps towards a subscription model have been granted extra time by reddit. There were conditions, but there were at least a few of them (Infinity and Relay are the ones that come to mind, but there was at least one more that I can't remember right now).
I think Narwhal is, but I don’t remember the details. Ironically, that’s the app I used to use, but the fact that they caved in and are cooperating with reddit just makes it an even less appealing option.
Infinity taking a few months to die gave me the time to get my alternatives ready:
Lemmy, general usage.
GBATemp, gaming stuff and jailbreaks.
Mastodon, off topic stuff.
