I made this app because I love learning languages. I'm aligning editions in different languages and adding them to the app. There are plenty of cool reading modes, like multi-parallel, hidden translation, sentence-by-sentence, and more. It also has dictionaries and grammar helpers. There are also many reading settings to make the process comfortable. This app is part of my Lingtrain project. Hope you like it.
