Testers Wanted: New Android Library Manager with Smart ISBN Extraction

[mecahi]

Hi everyone,

I’m working on a new Android app called LibraCore, designed specifically for managing local ebook collections (PDF and EPUB). I'm currently at the internal testing stage and would love some help from power users to stress-test the scanning and metadata engine.

Key Features:
- Smart ISBN Extraction: The app scans the actual text within your PDFs to find ISBNs for high-accuracy metadata matching (similar to Calibre's logic).
- Automated Metadata: Queries Open Library and Google Books APIs using ISBN or filenames.
- Privacy-Focused: Queries are anonymous; only the ISBN/filename is sent, with no personal data attached.
- Library Management: Includes List and Grid views, advanced filtering, and sorting.
- Manual Control: Full support for manual metadata editing and cover art management.
- Power User Export: You can export your entire library, including the SQLite database and all retrieved covers.

Important Note:
There is no in-app reader yet. This build is focused 100% on the "librarian" side—organizing files and getting metadata right first.

I’m looking for testers with diverse folder structures and larger collections (100+ files) to see how the scanner and extraction engine hold up across different devices.

If you’re interested in trying it out and providing feedback, please reply here or send me a PM. I'll need your email address to add you to the Google Play Internal Test list so you can download the app.

Thanks!
