Folio
Read full descriptionHide full description
Folio gets you to actually finish an English classic — 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 — plus its key grammar, idioms, and character names — 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 — 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 — 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 — 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 clearest difference is in-app purchases: Igrot Kodesh at none against Folio's 3. Igrot Kodesh also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, update cadence and ads there is nothing between them.
