I use jerboa but I'd try out any libre client. I'm not interested in proprietary apps.
Funny enough I never saw the need for dedicated website apps for e.g. reddit, but the fediverse is somewhat clumsy to use in a browser (I'm aware that browser extensions can help) so an app actually improves the experience a bit.
I'm using Jerboa, but it keeps crashing and on every statup complains that my instance is not compatible with the updated version. This drives me back to reddit and when it shuts off apps, I'll probably go back to real life.
In the latest version of Jerboa I can't change from All / Active anymore. 😊 Also I can't figure out for the life of me how to make a top level comment, they're doesn't seem to be a button for it.
Thunder didn't have sorting by top last time I checked. Liftoff can't add other instances than the 3 it comes with.
For me there's one massive flaw with the mobile web version of Lemmy - that when you go "back" after viewing a post the page scrolls near to the top of the page. If it weren't for that I'd happily give up the quest for an app.
