DialogMusicPlayer VS LibreraReader

Music Player GO and Simple Music Player don't require network access. You can also look out for the minimalistic Dialog Music Player in future. It could be promising.

Quick music player: Dialog Music Player is useful when you want to listen to an audio file in your files app.

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.

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.
