Bluesky
Is there no app client for Bluesky to use? I checked the F-Droid website for Bluesky.
I found Bridgy Fed to enable Bluesky to communicate with Mastodon.
It seems yet Bluesky has an Android app according to their GitHub repository (https://github.com/bluesky-social/social-app). However indeed nothing mentioned about F-Droid ; maybe some alternative Mastodon clients can also deal with Bluesky?
There's dhaaga which supports Mastodon and Bluesky, apparently.
