About this app

Find a book in seconds.

Book Finder turns the ISBN barcode on a book into a clear, useful catalog record.
Point the camera at an ISBN-13 barcode or type an ISBN-10 or ISBN-13 manually.
Book Finder validates the number, searches Open Library, and keeps the result in
your private on-device history.

Features:

- Fast ISBN-13 barcode scanning
- Manual ISBN-10 and ISBN-13 lookup
- Book title, author, publisher, language, year, topics, and edition information
- Searchable local scan history
- Mark favorite books
- Share a book record
- Previously retrieved records remain available offline
- Dark mode and modern Material 3 design

Privacy-minded by design:

- Camera images are processed on the device and never saved
- No account is required
- History can be deleted at any time
- Supported by AdMob banner and interstitial ads

Catalog metadata is provided by Open Library’s CC0 catalog. Availability and
completeness vary by edition.

Book Finder is brought to you by MobPage, an innovative mobile application
consultancy and developer under iGears Technology Limited.
Scan an ISBN or type it in to find and save reliable book records.

This app needs some work! The ISBN keyboard only has numeric input. (Some ISBN numbers are alphanumeric.) Barcode scan pulls up a generic bookseller page with plenty of pricing info, but very little about the book contents.

No results, doesn't scan ISBN and I don't even believe it is tied to a database, lmfao. Get it together!

What’s new

• Library restore — If you updated from the older Book Finder and your previous books disappeared, this update can bring them back automatically.
• Book covers — Saved and looked-up titles now show cover images from Open Library when available.

1. Install this update on the same phone where you previously used Book Finder.
2. Open Book Finder once and wait a moment on the home screen.
3. If books are found, you’ll see a “Library restored” message and they will appear under My library.
