I use lemmy occasionally. I do feel the impact of a significantly smaller community though. A lot of the subreddits I would regularly check are not even here. So unfortunately for now, I’m forced to use the official app. Tried the RSS route too, but it seems it would be too expensive for me.
I’m sure the lemmy community will continue to grow, so I’ll stick around.
All the apps I checked asked me subscribe. Couldn’t view anything without it. Maybe I haven’t found a free to use app on iOS.
