Leo: Read and Learn Words

Read books, translate, recall

Free · Designed for iPad. Not verified for macOS.

Translate words right in the book and learn them with spaced-repetition flashcards. Read books in a foreign language and remember new words as you read. READ THE WAY YOU LIKE EPUB, FB2 and PDF from Files, Mail or Telegram. A classic book page: font, size, theme and brightness the way you want. Bookmarks, notes and highlights. ONE-TAP TRANSLATION Select a word, a phrase or a whole paragraph — the translation appears at the bottom without closing the book. Dictionary form, part of speech and the sentence it came from. Translation runs on device, offline. YOUR WORDS STAY WITH YOU Tap “Add” and the word is saved with its sentence from the book. In the text it is highlighted by how well you know it: words you are learning in yellow, learned ones underlined. In every book, in every form of the word. SPACED REPETITION Cards come back right when you start forgetting them (SM-2, as in Anki). Exercises grow with the word: flashcard and multiple choice, then typing, then a gap in the book sentence. A 10–30 card mini-deck for when you have five minutes. WATCH YOUR VOCABULARY GROW Known words, day streak, daily goal, review forecast and achievements. YOUR DATA IS YOURS No sign-up, ads or analytics. Books, words and progress stay on your device and sync through your own iCloud between iPhone and iPad. Book languages: English, Spanish, Russian. The app interface is in Russian.
