A free program for Android, by Glose.

The best way to improve your reading comprehension is to get regular exposure to the English language. However, the most convenient way to get that exposure is not by reading books in your native language but rather by using an English-to-text converter to translate books and articles into your native language.

Our app, Glose – Social ebook Reader, is a convenient way to get exposure to the English language, and we’re proud that we’re the first text-to-text converter to be built with a completely open-source engine.

The Glose app is built on top of libreoffice, a free office suite, and uses a dictionary that is also available for free.
