Simply Fluent
The short answer
Simply Fluent is made for reading on your phone or tablet, also offline: your own EPUB, TXT and Markdown books, and a library you can filter by level from A1 to C2. The translations you save are shown above the words and phrases they translate, in every book in that language. Eppika is made for reading the books in its own library: bestsellers, classics and stories retold at your level, many of them with audio narration, on a phone, a tablet or, with a subscription, in a browser. If you want to read bestsellers retold at your level and listen to them, Eppika is the better fit.

Simply Fluent is a reading app
The app is built around reading a book page by page. These screens show a book in Spanish.
Made for books
You can read your own EPUB, TXT and Markdown files. The library adds short stories, and classic novels by writers such as Jane Austen and Jules Verne rewritten in modern language, with a filter for levels A1 to C2. You read page by page, and your place is saved in every book.
The meaning that fits the sentence
When you translate a word or phrase, you get all its meanings, and the one that fits the sentence is highlighted. If a word is part of an expression or an idiom, the expression is detected and you see the meaning of the expression, not of each word on its own.
Saved translations are shown in every book
A translation you save is shown above its word or phrase in every book you read in that language. When you mark it memorized, the translation is hidden and you read the word on its own. Every saved translation also becomes a flashcard, and favorites are picked first for each session.
