Book Finder turns the ISBN barcode on a book into a clear catalog record. Point the camera at an ISBN-13 barcode or type an ISBN-10 or ISBN-13 manually. The app validates the number, searches Open Library, and keeps the result in your private on-device history with favourites, sharing, offline access to past scans, dark mode, and Material 3 design. Camera frames are processed on device and never saved. No account required. Supported by AdMob ads.
Public store links verified on 2026-08-27. Availability may vary by region.
