Can’t really make apps for a site that doesn’t have an API. They did announce recently that Kbin’s API is nearly done, so soon there’ll be a flood of Kbin apps as well, and support for Kbin in all of the Lemmy apps too

and support for Kbin in all of the Lemmy apps

Very much doubt. I’m sure many will but not all. The API isn’t identical so they’d have to commit to maintaining both.

It would be great if someone created a fediverse browser native app. Log into all the platforms and add a translation layer to create a truly unique experience. Maybe it would only make sense if you could authenticate one account on all the activitypub platforms? I understand the amount of technical hurdles and maintenance to do so. I suppose I find the thought of experiencing them combined intriguing. If someone created A single app experience, in a intuitive way, I’d definitely give it a try. I can see lemmy posts on mastidon. Would be kind of cool if it could handle that and display those posts using a lemmy ui. But making it seamless.
