Every Fifth Word: English

Open a Ukrainian book and some of the words are already English. How many is up to you: the ring turns from 0 to 100%. At 20% every fifth word is English — hence the name. It still reads like an ordinary book, but every paragraph hands you a new English word in a context where the meaning is obvious without a dictionary. Your brain fills in the rest — that is how vocabulary sticks. If it does not, tap the word to see what it replaced. Learned a word? Remove it, and the freed percent goes to the next one. — For native Ukrainian speakers: the books and the interface are in Ukrainian — Your own books: EPUB, FB2, TXT — Fully offline: the dictionary lives inside the app — Word order never reshuffles when you change the percentage — Proper nouns and ambiguous words are never translated — Themes, typefaces, size, line spacing — No ads, no data collection Three days free. Then ten pages a day free, or a one-time purchase — not a subscription.
