Restricted Section

Your personal book catalog for iPhone. Scan a barcode to add a book, check if you already own something before you buy it, and browse your collection like a library.

iOS 17+ Swift License Privacy

  • Scan to Add

    Point your camera at any book's barcode. Restricted Section looks it up instantly via Google Books and adds it to your catalog with cover art, author, and full metadata.

  • Check Before You Buy

    In a store? Scan the barcode to instantly see if it's already in your library. No more buying duplicates.

  • Track Your Reading

    Mark books as Unread, Reading, or Finished. Add a star rating, personal notes, and track which series volumes you own.

  • Browse by Series

    Group your books by series and see at a glance which volumes you have — and which are still missing from your collection.

  • Wishlist

    Books you want but don't own yet live alongside your catalog in one place, filtered by their own status.

  • Fully Private

    Everything stays on your device. No account, no cloud, no tracking. See the Privacy Policy for the full details.
