ShelfMark vs Addicted to Reading

A quiet reading tracker for people who love books more than apps. ShelfMark keeps your reading life in one calm, paper-warm place. Log the page you are on, keep a streak alive, and save the lines worth keeping. No account, no feed, no noise. MADE FOR READERS - Three shelves: to be read, reading, and finished. Move a book with a tap. - Quick page updates with percent complete, pages a day, and time left at your current pace. - A daily page goal beside your grace-day reading streak. - Search your library, filter by genre, and sort by recency, title, author, or progress. - A quote wall with the book, page number, and an optional photo of the page. - A yearly reading goal and Wrapped view with pages, streaks, genres, fastest reads, and monthly activity. - A private Home and Lock Screen widget for your current book, pages today, goal, and streak. - A complete local backup, additive restore, and Delete All My Data control. FREE AND LIFETIME ShelfMark is free for up to 3 books and 5 saved quotes. Reading progress, streaks, daily and yearly goals, search, backup, restore, deletion, and the widget stay useful without paying. A single Lifetime purchase unlocks unlimited books and quotes, the 30-day Reading Pulse, finish-date pace plans, full Wrapped statistics, and the one-page Reading Year PDF. It is a one-time purchase, not a subscription. Existing records always remain readable and editable. PRIVATE BY DESIGN Your reading library stays locally on your iPhone or iPad. No account, no analytics, and no tracking. Widget content uses Apple's private on-device App Group storage and is marked privacy sensitive.

DuoBook turns your PDF library into a daily reading habit. Import any PDF you own, set a simple daily page goal, and let DuoBook keep you accountable — Duolingo-style — with a win streak that grows every day you hit your target. No account, no sign-up, no ads. Your books and your progress never leave your device. HOW IT WORKS Drop in your own PDFs — novels, textbooks, reports, whatever you're working through. DuoBook copies each file locally, generates a cover, and adds it to your shelf. Open a book, read at your own pace in a clean full-page PDF viewer, and DuoBook quietly tracks the pages you've read today. Set your daily objective (10 pages a day by default, fully adjustable) and watch a progress ring fill up as you read. Hit your goal and a pixel-art campfire lights up to celebrate — miss a day and your streak resets, just like the habit apps you already know. STAY MOTIVATED - Daily win streak with a best-streak record, so you always know your all-time high - A dedicated Statistics screen: an activity calendar for the last 5 weeks and a bar chart of your last 7 days, so you can see your habit take shape - A home screen widget (via WidgetKit) that shows your current streak and how many pages are left today — no need to open the app to stay on track - A profile screen with your own avatar, name, and bio BUILT YOUR WAY - Import unlimited PDFs from anywhere on your device - Automatic page-by-page progress tracking as you read — pick up exactly where you left off - Light and dark mode, switchable anytime - A distinctive retro "green terminal" look: neon green on black, a pixel font, hand-picked pixel-art icons, and an animated dot-matrix navigation bar — DuoBook feels like nothing else on the App Store PRIVACY FIRST DuoBook doesn't ask for an account and doesn't show ads. Your PDFs, your reading stats, and your streak are stored entirely on your device (and synced to your widget through Apple's own App Group storage). Nothing is uploaded, nothing is tracked. Whether you're chipping away at a textbook, working through a backlog of novels, or just trying to read more consistently, DuoBook gives you the small daily nudge — and the streak to prove it — to actually finish what you start. Download DuoBook and start your streak today.
