I'm using Voyager browse and interact with Lemmy.
It looks more or less exactly like Apollo and it's a webapp. There's a few small things that's not exactly as a native app, like double tapping the top of a scrolling window to scroll to top, but it's really minor.
I bet most people wouldn't know it was a webapp if they weren't told.
It even works with the sharing intent so I can share to native apps. Pretty awesome.
