I've downloaded all the available Lemmy apps I could find
They all work better than the official Reddit app. I know it's a low bar to clear, but some of them have barely been out for two months and are in alpha/beta stages.
The only big issues I've run into are instance related because of those asshole ddos'ers
Other open source apps to shout out:
Infinity (Currently using to type this)
There's also Slide, but it's pre alpha I think. Not totally ready for normal wear and tear
