neko(fork of tachiyomi that works well with mangadex) for manga

I use neko which is a fork of tachiyomi. But I'm sure the built-in browser would work fine

You could use Tachiyomi Neko https://tachiyomi.org/forks/Neko/ and do the same thing again.

Neko - this is a mangadex focused fork of tachiyomi. if you are a diehard mangadex stan, this is the tachi for you. Sign in and instead of hunting down all the manga you are reading, you can just import it all into lists that you have already set up or into categories you already have based on status - read, not read, dropped, etc]. Really strong filters that you can block updates from certain groups and languages from popping up when you update your library.
