It's overall pretty good so far but I find that the swipe interactions with comments and posts can be a bit clunky. I frequently will swipe too far and accidentally save a comment when I just want to upvote. I'm still so used to Sync though.
The only thing I'd change about Connect is the visability of comment interaction buttons but other than that with a few tweaks to font sizes and stuff it's a fairly similar experience to RIF.
As a former RIF user, I personally like Liftoff, which you can get in the Play Store, but other popular options are Jerboa, Thunder, Connect for Lemmy, wefwef, and Summit.
Connect and Liftoff are able to give a similar RIF UI. I was really liking Liftoff until I just now noticed why it was so "quiet" despite trying to chat a storm: it has no inbox and no notifications. Connect does, though. But it has less options for customizing the layout...
I want something that takes the best of both and smushes them together. 😩
