i recall seeing links to one such app given as answers to source requests quite often a long time ago, but i've not seen it recently.
basically, it was a “reader” site that didn't host its own content but was used to read hentai from other sites, definitely including nhentai and imgur, probably also exhentai, maybe even github gists or something crazy like that, not sure anymore.
the main reason i'm looking for it now is because i think it supported continuous scrolling mode and i'd like to use that for some stuff on nhentai. but even if i'm misremembering and it didn't support that, i'd still like to find it again just out of curiosity.
so does anyone remember what that was?
