ReadGrow vs Folio

ReadGrow is a book-centered reading companion designed for readers who want to retain more from every book they read. Whether you're reading fiction, nonfiction, books in your native language, or books in English, ReadGrow helps you track your reading journey, capture your thoughts, and keep your books, reading progress, and notes together in one place. For readers enjoying books in English, ReadGrow also includes built-in vocabulary collection with automatic IPA pronunciation and definitions, making it easy to expand your vocabulary naturally through reading while preserving the journey of every book you read.

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.
