I’m assuming, out of all the Activity-Pub connected ‘Fediverse’, there are a handful of instances that get the most activity.
That being assumed, is there an app (mobile and otherwise) that, functionally, includes most of these instances?
For example, is there an app that can seamlessly handle Mastodon, Lemmy, Friendica, Hubzilla, Peertube, etc?
There is Fedilab on the F-droid store that supports Mastodon, Pleroma, Pixelfed and Friendica.
Thats all that I am aware of.
Last time I used it, Fedilab also supported PeerTube. The same developer also released a specific PeerTube app, though so I don’t know if they split the video functionality out or left it in.
