I like the idea of a kbin app, but I wonder if it's just because I'm so used to everything having its own app. I got the jerboa app and tried to use Lemmy. It was so busy that I couldn't get anything to work. So I ended up on kbin. I like it, at least so far. Accessing it through a browser works, but maybe it would be better to have an app tailored to it. Either way I don't think I'm going back to reddit.
Edit: 14 hours later and I can install it just fine. CloudFlare broke it but it seems that it's gone back to normal working status now that CloudFlare is off.
The dev seems really active on here and I've got a feeling over the next few weeks when he sorts out some of the backend challenges, he'll look into some of the UI/UX improvements. The site from what I can see runs off Laravel / PHP and it's on GitHub so people can submit PRs and help him out with work.
I'll be looking into it myself to see if we can get click to collapse nested comment threads working, along with some other UX aspects.
I think getting one of the app devs interested in kbin would be pretty handy though, but might be hard if the main dev is actively working and improving the site
