I'm really happy with Arctic so far. It does not make my iPhone burn my hands as other clients had (Avelon, I look at you), and it can read a lot of media, which is really nice. The in-app browser doesn't appear in a card, which is also nice, and does not make the iPhone hot (again, Avelon, can you stop doing that?).

Though it seems that I shit on Avelon quite a bit, that's not the case, it's a decent client, and I really like the URL conversion/error handling it's doing when you open unknown communities and Lemmy links. That's something more for selfhosters when their instance doesn't know specific content, I'm pretty sure big instances are not that much concerned with these kind of errors, and Avelon handles them beautifully.

I've also tested a bunch of other clients too, but generally, either they don't respect the iOS standards that well (hello shitty Electron apps), or they can't read media formats that well.
