Bookworm helps you track every book you own and every book you want. Scan a barcode at any bookstore or fair and know instantly — owned, wanted, or new find.
Simple and powerful tools that fit seamlessly into how you already discover and buy books.
Instant ISBN Scanning
Point your camera at any book's barcode. Bookworm looks up the title, author, and cover in under a second — no typing required. Perfect for book fairs, garage sales, and library sales.
Owned & Wanted Lists
Mark books as Owned or Wanted. Switch between filtered views at a glance. No more buying books you already have on the shelf.
Export & Import CSV
Your data is yours. Export your full library to CSV for backup or spreadsheet use. Import from a CSV to migrate from another system.
Generate PDF Catalogues
Print or share a formatted PDF of your library — all books, owned only, or wanted only. Great for insurance records or sharing your wishlist.
Google Books Auto-Fill
Search by title and select from results. Book details, cover art, author, and publisher fill in automatically — no manual data entry needed.
Light & Dark Mode
Follows your iOS system appearance automatically, or set it manually. Looks great at midnight in bed or bright daylight at the market.
