> Can anyone recommend a high quality ebook reader app for Android, that would be compatible with one or more of the formats this site offers?

I use [Librera Reader](https://f-droid.org/en/packages/com.foobnix.pro.pdf.reader/] and [Voice](https://f-droid.org/en/packages/de.ph1b.audiobook/) for audio books.

[KO-Reader](https://f-droid.org/en/packages/org.koreader.launcher.fdroid...) is also recommended, but the one above I found easier to use, though both seem highly recommended.

I found these Android apps from this [post on r/androidapps](https://old.reddit.com/user/Jackie7610/comments/lr5gag/list_...)

Basically just look for epub, as that is the open standard - though really it doesn't matter if you use [Calibre](https://calibre-ebook.com/) as it can convert between them, but you have to check the types supported yourself...

> Also what is this "advanced epub" format they have? I can't see where they describe the actual difference with "compatible epub".

They have [an explanation here](https://standardebooks.org/help/how-to-use-our-ebooks#which-...), but I would say, when in doubt, just go with the compatible one.

Besides, it's just a book, I doubt anything will explode if you use the wrong the version...
