Excellent cross language reader

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.

Surprisingly EPUB reader is very good. Table of contents, switching between chapters. The only thing I wanted to add is copying text, currently you can't do it. ​
