Beautiful, simple reading.

All in one app. Finally.

For Calibre users

You've spent years curating your library — tagging, rating, organising series, building the perfect collection. Every other mobile reader treats that work as invisible. CalibReader reads your Calibre library as you built it: series in order, ratings intact, custom columns respected, metadata all there.

The built-in reader means you never need to leave the app. Browse, find, read — in one place, on your device, no internet required.

✓ Calibre metadata, fully preserved ✓ Two-way sync with your desktop library ✓ Browse and read in the same app
Don't use Calibre? That's fine too.

CalibReader is also just a genuinely great ereader — no strings attached. Load your EPUB files directly from Dropbox, Google Drive, OneDrive, or a local folder. No account. No ecosystem. No store trying to sell you books.

A beautiful library browser, a clean reading experience, powerful filtering and series support. Everything the big-name apps have, none of what you resent about them.

✓ Load books from any cloud storage ✓ No account or sign-in required ✓ No lock-in, ever
What sets CalibReader apart
01

Actually local

Your library lives on your device. Not in a cloud you don't control. Not behind an account that could be deleted. Read on a plane, underground, anywhere — your entire collection, always there.

02

Calibre-native

Reads your Calibre library directly — series, metadata, custom columns, tags, ratings, all of it. Not an approximation. Your library as you built it, on your device.

03

One price, forever

$9.99. Once. No annual fee. No "pro tier." No features held hostage. The app you buy today is the app you keep using indefinitely.

Every feature
you actually need.

Not a stripped-down reader bolted onto a sync engine. Built from the ground up for Calibre libraries and serious readers.

📖

Beautiful built-in reader

A full-featured ereader is built right in. No bouncing between apps. Tap a book in your library and start reading immediately, with clean typography and adjustable settings.

Super-fast library sync

Delta sync means even libraries of thousands of books stay current in seconds, not minutes. Add a book in Calibre on your desktop, pick it up on your device moments later.

🔄

Two-way read/unread sync

Mark a book finished on your tablet — it's marked in Calibre too. Your read status follows you, not the other way around.

Two-way
📍

Persistent reading position

Pick up exactly where you left off, every time. Reading position syncs across sessions automatically for all in-progress books.

📚

Full metadata display

See series, series index, tags, rating, publisher, and more — all customizable. Show what matters to you, hide what doesn't.

Dedicated series view

Series readers,
this one's for you.

Dedicated series view shows all series in your library. Tap any series to see every book in order — no searching, no manual sorting, no confusion about what comes next.

Series index, book count, and cover art. Exactly what you'd expect, done right.
