OpenDocument.droid VS LibreraReader

That appears to be because Session uses Firebase as a dependency.

Per F-Droid's definition of "the upstream source code is not entirely free":

https://f-droid.org/en/docs/Anti-Features/#UpstreamNonFree

This seems to be a case of "damned if you do; damned if you don't". Session relies on Firebase to get faster notifications from Google servers. This can be disabled in the applications preferences but changes the behavior from push-notifications to polling Session's decentralized messaging network, which makes messages notifications slower.

For the sake of clarity it would be nice if instead of making such a vague pronouncement, F-Droid would specify precisely what about the upstream source code is not entirely free.

LibreOffice & OpenOffice document reader | ODF (version 3.12): Document reader & file editor for Libreoffice & OpenOffice | ODF: ODT, ODS +more

Searching on the project's Github project, there's an issue about this "The upstream source code is not entirely Free" on F-Droid meaning ?. I doubt you'll find a better answer than that.

I've been rather happy with Librera, although when reading foreign languages, I prefer KOReader for its locally installed dictionary lookups (you have to add them). Note that these are both reader software, first, and not advanced library management packages (as far as I know).

The last I checked, Librera also had two versions on the Play store, with the paid pro (or whatever) version sending a few dollars towards the Ukrainian developer. Who's been donating to the defense efforts since the war started. Or was; that language now appears to be gone from the web site.

Anyway, for those not familiar with FDroid and/or who want to contribute to development other that via PayPal -- or, looks like now that would be Patreon.

For those who asked: Humble Bundle is another source of DRM-free ebooks.

Google Docs → Librera Reader, Collabora Office

On Android, the text-to-speech I find is better with https://librera.mobi/

Looks like it has been suggested at least once on GitHub. Maybe give a +1 to that issue to show interest?

Librera Reader (version 8.9.12): Book and PDF reader

I use Libera which has everything i need for a reader, to view full-screen is essential bc it makes use of all the space on phone.

Librera reader, perhaps? https://librera.mobi/

I personally use Librera on Android with google translate.
