Fox Reader turns ANY BOOK you own INTO a lifelike AUDIOBOOK, ENTIRELY OFFLINE on your iPhone. Import an EPUB, PDF, or MOBI, press play, and listen in natural, expressive voices. No cloud. No account. Nothing leaves your device. It's a real reader, too: follow every word as it's spoken, study what you read, and track the habit, all in a beautiful library that's yours alone. LISTEN TO ANY BOOK, OFFLINE Lifelike, on-device AI narration for anything you import. Choose from multiple expressive voices and listen anywhere your iPhone goes: car speakers, AirPods, or a walk with no signal. No streaming, no buffering, no internet required. FOLLOW ALONG, WORD BY WORD Every line highlights in sync with the narration, so reading and listening reinforce each other. Ideal for learning a new language, building comprehension, supporting dyslexia or ADHD, or simply keeping your place when you glance down. Fox automatically skips tables of contents, front matter, and decorative clutter, so you only hear the story. CATCH UP WITH AI SUMMARIES Lost the thread? Fox generates instant 3-bullet recaps of the last few pages, your current chapter, or the chapter you just finished: so you can jump back in within seconds. A READER DESIGNED AROUND YOU Eight hand-crafted themes, including Sepia, Dark, Forest, and Twilight. Fine-tune fonts, sizes, weights, line spacing, margins, and alignment. Smooth page-curl animations and orientation lock round it out. HIGHLIGHTS, NOTES & VOCABULARY Highlight passages in six colors and attach notes to any range of words. Save words to a personal vocabulary list, then make them stick with five AI word games: Quiz, Puzzle, Hangman, Word Guess, and Riddle Rush. SEE YOUR READING GROW Every reading and listening session is tracked. Set daily and yearly goals, build streaks, and watch a 14-day activity chart with breakdowns by author and format. A LIBRARY THAT ORGANIZES ITSELF Build custom collections with emojis and pin favorites to your Home Screen. Smart collections auto-group your books: Currently Reading, Almost Finished, Short Reads, Long Reads, and more — while AI genre classification sorts the rest for you. TRACK SERIES & DISCOVER MORE Follow multi-book series from start to finish, keep a wishlist of books you haven't imported yet, and find new titles from authors you already love. Import your Goodreads library by CSV. SYNC ACROSS YOUR DEVICES Your library, reading progress, highlights, notes, and preferences move with you over iCloud. Start a chapter on iPhone, finish it on iPad, exactly where you left off. PRIVATE BY DESIGN The neural voices, AI summaries, and genre sorting all run on your device — not on a server. No account, no tracking, no uploads. Your books and your notes stay yours. SUPPORTED FORMATS EPUB · PDF · MOBI · TXT. Import from Files, email, iCloud Drive, or any document source.

Highlight anything in your PDFs and EPUBs, add your own notes, and export it all as Markdown, CSV, or a clean PDF. Your highlights don't stay locked in the file — take them to your notes app, your research, anywhere. Read both formats, organize your library, and keep everything on your device. Bring books scattered across Files, iCloud Drive, Google Drive, and Dropbox into one organized shelf. Read them in a built-in PDF and EPUB reader, highlight and annotate as you go, and — when you're reading in a foreign language — save any word to your personal dictionary, get an instant definition, translate it, and quiz yourself with spaced-repetition flashcards. It all happens on your device. YOUR BOOKS, BEAUTIFULLY ORGANIZED Import PDFs and EPUBs from Files, iCloud Drive, Google Drive, Dropbox, or any cloud storage app installed on your device. Books appear on a visual bookshelf with colored spines. Group by category, search by title or author, and pick up right where you left off with the Currently Reading bar. BUILT-IN PDF & EPUB READER A native reader for both formats — no third-party apps needed. Page through chapters, jump to any section from the table of contents, search within a book, and your reading position is saved automatically. SCAN PHYSICAL BOOKS Point your camera at any book's ISBN barcode or type it in manually. Lexifolio fetches the title, author, and cover from Open Library so your physical and digital collections live side by side. PERSONAL DICTIONARY (Pro) Select any word while reading to save it with a definition and translation. Definitions are generated on-device using Apple Intelligence, or look up any word online via Wiktionary. Tap the speaker icon to hear pronunciation in any language. Perfect for reading in a second language. HIGHLIGHTS & ANNOTATIONS (Pro) Mark passages in color, attach notes, and browse all your highlights organized by book. Everything stays on your device. VOCABULARY QUIZ WITH SPACED REPETITION (Pro) Saved words become flashcards. The SM-2 spaced repetition algorithm schedules reviews at scientifically proven intervals so you actually retain what you learn — the same system used by Anki. READING STATISTICS (Pro) Track your daily reading time, streak count, and per-book progress on a visual chart. See exactly how much time you spend with each book. AI BOOK SUMMARIES (Pro) Generate a summary of any book using on-device Apple Intelligence — no data leaves your device. Requires a device with M1 or later. You can also connect your own API key from OpenAI, Google Gemini, or any OpenAI-compatible service for cloud-based summaries on any device. MULTI-LANGUAGE TRANSLATION (Pro) Configure up to 5 language pairs — English→German, Spanish→French, Italian→German, or any combination. Translations use Apple's built-in Translation framework and work offline. Set your active pair and every saved word gets translated automatically. BACKUP & RESTORE Export your entire learning data as a single .lexifolio backup file. Save it to Files, iCloud Drive, or anywhere you like. Restore anytime to get everything back — dictionary, highlights, reading positions, and ISBN-scanned books with covers. POWERED BY APPLE INTELLIGENCE On-device AI for word definitions and book summaries — your text never leaves your device. Works with multiple languages. Requires iPhone or iPad with M1 chip or later. On older devices, use Wiktionary for definitions and Apple Translation for translations — both work without Apple Intelligence. 100% PRIVATE No accounts. No tracking. No ads. No analytics. No data collection. Your library, dictionary, annotations, and reading history stay on your device. Period. FREE TO TRY The bookshelf, PDF/EPUB reader, and barcode scanner are completely free. Pro features (Dictionary, Annotations, Quiz, Statistics, AI Summaries, Translation) include a 7-day free trial, then a one-time purchase of $7.99. No subscriptions ever..
