What kind of phone are you using? On my note 20+ ultra whatever the fuck, I haven't noticed any slowdown issues.
Though I am using the google play version, and there was a problem prior to this most recent update where at least one link would crash the app (haven't seen it anywhere else yet).
I like liftoff but jerboa is the only one with font accessibility settings. Need a magnifying glass for some stuff on others.
Also jerboa has collapsible comments, others do not. Liftoff let's me use multiple instances at once, others do not. Thundar feels like RiF but not the same features yet.
I'm enjoying connect for Lemmy. Jerboa is also very good but the instance I signed up with hasn't updated to the latest Lemmy version, jerboa does use the latest Lemmy version, so the app sometime crashes for me.
