## What is ERReader?

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

At 10% every tenth word is Russian. It still reads like an ordinary
book, but every paragraph hands you a new Russian 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.

The alphabet is a setting, not a wall. Russian words can be shown
in Latin letters (krovat'), in Cyrillic (кровать), or both at once —
switch whenever you are ready, mid-page, without losing your place.

Learned a word? Remove it, and the freed percent goes to the next one.

— 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 replaced
— 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.

## Version history (last 2 releases)

### 1.1 — 2026-09-09

Turning a page is now animated, and you can choose which way pages move: sideways, like a paper book, or up and down, which is easier one-handed. Settings → Turning pages.

New: justified text. Settings → Type → Justify gives the page an even right edge, with hyphenation switched on alongside it so the lines do not break into gaps.

### 1.0 — 2026-09-01

No release notes.
