Addicted to Reading: Gamified

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.
