duoBooks: Read & Translate

This app first asked me which language to use for translation, but when I tried my first sample reading it translated the Spanish to German. When I figured out how to fix this, it then said I had no more free translations so I have no idea if I’d want this app. Additionally there seems no way to search for books in a particular language.

I want to read in French and English. That are not my native language and this app helps a lot

This app has revolutionized my language study! I use it with purchased ePub files in a language I am studying. The interface is intuitive. It's also very fast to use and provides a smooth experience during long reading sessions. The developer is receptive to feedback, even filling in details to improve dark mode based on user feedback.
