About

Folio

Features
Read full description

Folio gets you to actually finish an English classic โ€” in the original, cover to cover. Most reading apps drop you into a hard text and hope you cope. Folio is different: it's a prep course, not just a reader. Before you read, you pre-study the ~600 words that cover 95% of that specific book โ€” plus its key grammar, idioms, and character names โ€” using spaced repetition with self-rated confidence. Once your "reading power" is high enough, you read the unabridged original with a tap-to-translate dictionary and LibriVox audiobook narration. HOW IT WORKS 1. Pre-study the book. Spaced-repetition flashcards for the vocabulary, grammar, idioms, and names that unlock the text โ€” chapter by chapter. Folio catches the words you only think you know. 2. Watch your reading power rise. A per-chapter gauge fills as you study, rewarding real recall. 3. Read the original. The full, unabridged text with tap-to-translate and audio. Finish it and earn a completion card. IN YOUR LANGUAGE The texts stay in English. Definitions, notes, and example translations appear in your language: Japanese, Simplified Chinese, Spanish, Korean, Brazilian Portuguese, or French. THE LIBRARY A growing library of public-domain classics โ€” start free with Alice's Adventures in Wonderland, then unlock the full collection. HONEST BY DESIGN - No account, no sign-in. Everything is stored on your device. - No ads, no tracking. - Book texts from Project Gutenberg and Standard Ebooks; narration from LibriVox โ€” all public domain. Start free, and read your first classic to the very last page. Terms of Use (EULA): https://readfolio.co/terms Privacy Policy: https://readfolio.co/privacy

Verdict

The call

Folio and ReadOcean are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
