Readius is a reading companion that connects you to the readers of the same book anywhere in the world.

Scan a barcode to add a book, track your reading, and watch a quiet map light up with everyone else who is reading it right now.

WHAT YOU CAN DO
━━━━━━━━━━━━━━━━━━━━━━

📷 ADD BOOKS IN SECONDS
Scan the ISBN barcode on the back cover. No typing, no searching.

📖 TRACK EVERY READING SESSION
Start a timer when you sit down with a book. Pages, minutes, and notes are all kept together — and it all works offline.

🌍 SEE THE WORLD READING WITH YOU
Every book has a reader map. Watch how a novel travels across countries and cities. Reading alone stops feeling lonely.

✍️ KEEP THE LINES THAT STAYED WITH YOU
Save the sentences that moved you. Other readers can resonate with them, and you'll see which lines stayed with people around the world.

🌱 WATCH YOUR READING GROW
Your Growth Score reflects consistency, range, and depth — not just how many books you finished. A daily heatmap shows the shape of your reading year.

🏆 JOIN CHALLENGES AND BOOK CLUBS
Take on annual or weekly reading challenges. Start a book club and read together, near or far.

💬 TALK ABOUT THE BOOK, NOT THE ALGORITHM
Book-centred conversations, automatically translated so language is never the barrier between two readers of the same book.

BUILT AROUND READING
━━━━━━━━━━━━━━━━━━━━━━

• WORKS OFFLINE — Reading happens on planes, in cafés, at night. Everything you record is saved on your device first and synced when you're back online.

• NO GPS TRACKING — Readius never reads your device location. If you want to appear on the reader map, you tell us your region yourself, and only
aggregated counts are ever shown.

• NO STRANGER DISCOVERY — There is no matching by age, looks, or gender, and no private messaging with strangers. The book is the meeting point.

• MULTILINGUAL — Available in 10 languages, with automatic translation for reader posts and highlights.

Readius isn't an app for recording books. It's a navigator into the world of books.
