...care to elaborate why you can't visit a website on Android and how this is relevant to anyone else?

It is on the list of "LibRedirect", and it seems to be a self-hosted front-end to Instagram, not something one could just simply download from F-Droid and use.

Oh you mean that it's a website and not downloadable software, right

Yeah, I thought I found a FOSS, easy-to-use frontend to Instagram that could replace the Instagram app. :/
