1. Best for cataloging the books you actually own — privately
Better Bookshelf
Full disclosure: Better Bookshelf is our app. But it exists precisely because nothing on this list solved the whole problem, and it takes a different lane than every other option here: it's built around the shelves you own, not a social feed.
Getting organized starts with a photo. Take one clear picture of a bookcase and AI identifies the books from their spines, marks where each one sits, and lets you add the matches to your library together; uncertain ones you identify by barcode, title, or a book you already own. Later, search a title and the app opens that shelf photo with the spine highlighted and the books beside it. For single books, barcode scanning catalogs one in about a second from a four-source lookup (Google Books, ISBNdb, and OpenLibrary twice over).
It also brings your reading life together: physical books, Kindle, and Audible merge into a single entry with format badges, and your Kindle highlights sync in via Readwise, attached to the books they came from. Your catalog stops being an inventory list and becomes a record of what each book gave you.
And it's private by design. No sign-up, no ads. Your library and shelf photos live on your phone, backed up to your own Google Drive with one tap, exportable to CSV anytime. Free for your first 50 books; a one-time US$29.99 Unlimited upgrade removes the limit and includes six whole-shelf AI scans. No subscription.
