Nice.

I also quite like [Book Reader](https://gitlab.com/axet/android-book-reader), specially their handling of text in PDFs is fantastic (it makes text readable automatically, instead of having to zoom in)

Curated list of useful Open Source applications for GrapheneOS

Nice list!

I would also add [Librera Reader](https://f-droid.org/packages/com.foobnix.pro.pdf.reader/) for ebooks

[InviZible Pro](https://f-droid.org/en/packages/pan.alexander.tordnscrypt.stable/) for i2p, tor and dnscrypt

And [Scrambled Exif](https://f-droid.org/en/packages/com.jarsilio.android.scrambledeggsif/) for deleting metadata from photos.
