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.

Verdict
The clearest difference is ads: ERReader at none against Bright BSL's shown. ERReader also leads on update cadence (weekly vs fortnightly). Bright BSL's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price and in-app purchases there is nothing between them.
