I think for Lemmy to really pop off, some proper iOS apps is needed. There's a few in testflight (using memmy atm) but that's far too complicated for a regular person to do.
I'm also finding a lot of things a bit unintuitive, especially after being used to how reddit works.
Might just be the app I'm using, but finding new communities and content is a bit cumbersome.
Same benefits we got with RIF/Apollo over Reddit. I'm not gonna mention any specific ones but the idea is that the devs of Lemmy can focus on working out site bugs etc. while app devs can focus on adding features not currently available on the web.
But Lemmy is open source, so any improvements could just be made to Lemmy's frontend/PWA, maintaining a bunch of native apps made more sense when they were hacking around closed source limits.
