Half-read business books pile up. Bring yours here, pull out the ideas worth acting on, and listen to them on the commute. Reading is always free. You finish a business book and keep three ideas. Two months later, one. MBook catches those ideas while you read, then turns them into a deck you can review in five minutes or listen to on the way to work. Bring your own book. Reading is free, with no limits. HOW IT WORKS 1. Add a book you own. EPUB, PDF or FB2. 2. Read it in the app. Reading stays free on every plan. 3. Turn it into cards when you are ready. MBook pulls out the concepts, tactics and frameworks worth acting on. READ ANY BOOK YOU OWN A clean reader with chapters, saved position and type that stays out of the way. No catalogue, no rented titles, no subscription to a library. Your files stay yours. CARDS BUILT FOR ACTION Eight card types: Concept, Insight, Strategy, Tactic, Framework, Quote, Summary, Metaphor. Tactics tell you what to do on Monday. Frameworks hand you a lens for the next decision. Quotes preserve the author's exact words for when you cite them. LISTEN ON THE MOVE Hear your deck read aloud during a commute, a walk or a workout. Five voices to choose from. The book you never had time to open becomes the drive to the office. CARDS IN 180+ LANGUAGES Read the original in English and get your cards in your own language. Or flip it, and study the language while you read. KEEP WHAT MATTERS Save the cards that land. Group them into collections by project or theme. Share one as an image when it deserves an audience. WORKS OFFLINE Books, cards and audio you have already loaded open with no signal. Flights and subways included. PRIVACY YOU CAN VERIFY No account. No email, no password, no phone number. MBook knows you by a random ID your device generates. No ads. No usage tracking. Your books never train AI models, and one tap in the app erases everything you have stored with us. PLANS Free: read as many books as you like, and build card decks from 3 of them. MBook Pro: card decks from 10 books a month, plus audio narration. Billed monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews each period unless you cancel at least 24 hours before it ends. Manage or cancel it in your Apple Account settings.

Synapps is now MBook. Your account, your books and your cards carry over untouched. This is the largest release since launch. READING IS NOW FREE AND UNLIMITED MBook opens EPUB, PDF and FB2 files in a real reader: chapters, saved position, and page turns that keep up with you. Read as many books as you like on any plan. Card decks stay the paid part. READ WITHOUT UPLOADING Choose "Just read" and the book never leaves your device. Nothing reaches our servers, and it opens at 30,000 feet. LISTEN TO YOUR DECK Cards can now be read aloud in five voices, so a deck fits inside a commute or a walk. Included with MBook Pro. COLLECTIONS AND SHARING Group saved cards into collections by project or theme. Share a single card as an image when it deserves an audience. CARDS IN 180+ LANGUAGES Read the original, get the cards in the language you think in. ONE PLAN INSTEAD OF THREE Starter and Unlimited are retired. MBook Pro covers card decks from 10 books a month plus audio narration, billed monthly or yearly. PRIVACY We took usage analytics out of the app. No account, no email, no tracking. One tap in Profile erases everything you have stored with us. FIXES Home opens from your local library first, so your books appear at once and stay readable with no connection. Restore Purchases now refreshes from the App Store. It used to read only the cache on your device, which is empty right after a reinstall, so it looked like nothing happened. The reader opens your book instead of a sample. Books show their real title rather than the file name. Covers are stored on device and show up offline. Page turns are smoother and the table of contents is numbered. Card decks no longer duplicate a book when generation is retried.
