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. Your whole library, in your ears: and nothing leaves your phone. Download Fox Reader and press play.

Readarium
Read full descriptionHide full description
Save the whole article. Read it clean, offline, or listen. Readarium is the free, private place for everything you want to read later. Share a page from Safari and it comes back as the article alone: no ads, no pop-ups, no cookie banners, ready to read anywhere — including on a plane. THE COMPLETE ARTICLE, EVEN ON SITES YOU PAY FOR Most read-later apps re-download the page on their own and end up with the preview. Readarium saves the page exactly as Safari shows it to you. If you're signed in to Le Monde, The New York Times, Mediapart, the FT, Medium or a paid Substack, you get the whole article — and Readarium tells you when a save is only the preview, so you know to share it again from Safari. SAVE FROM ANYWHERE Share from Safari or any browser, paste a link, subscribe to RSS feeds, or drop in PDF, EPUB, Markdown, HTML, text and email files. Bringing a library over from Pocket, Instapaper, Raindrop, GoodLinks, wallabag or browser bookmarks takes a single import. READ WITHOUT DISTRACTIONS Serif, sans-serif or rounded fonts, adjustable size and spacing, light, sepia, dark and pure-black themes. Highlight passages, add notes, and find anything in your library with full-text search. READY OFFLINE Text and images stay on your device. Build a self-contained HTML or clean PDF copy of any article for the days without signal. The “Make Clean PDF” shortcut turns any web page into an ad-free PDF straight from the share sheet, and “Listen to Page” starts reading it aloud. LISTEN Play any article aloud, or send it to VocaRead for natural voices, CarPlay and background playback. YOUR NOTES, YOUR TOOLS Export articles and highlights as Markdown to Obsidian or any notes app. Reading reminders, widgets, Spotlight and Shortcuts keep what you saved within reach. PRIVATE BY DESIGN No Readarium account, no ads, no tracking. Your library lives on your devices and syncs through your private iCloud — nobody else can see it. COMPLETELY FREE Everything included, no subscription, no premium tier. Built by a solo indie developer who believes reading should be free, private and beautiful.
