## What is Tenth Word?

Open a Russian book and some of the words are already English.
How many is up to you: the ring turns from 0 to 100%.

At 10% every tenth 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 Russian speakers: the books and the interface are in Russian
— 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.
