Your library.
Always with you.
A book library app that respects your privacy. Catalogue your collection, track what you've lent out and what you've borrowed, build a wishlist, and find any book in seconds by ISBN scan or title search. Share your library with your household via iCloud. No account required. Free to use, with LeanBooks Plus as an optional upgrade.
Everything a bookworm needs.
Nothing they don't.
Your Collection, Organised
Scan a barcode or search by title — LeanBooks pulls in the cover, synopsis, author, and publication details from Google Books automatically. Assign shelf locations and browse by author, title, or where the book lives.
Lending, Both Ways
Track books you've lent out and books you've borrowed — with the person's name, due date, and overdue status at a glance. Reminders alert you before loans are due. No more "wasn't it you who had my copy?" moments.
Wishlist for the Next Haul
Spotted a book you want but don't own yet? Add it to your wishlist. Browse it at the bookshop or before your next order. Never forget a title again.
Family Library
Share your entire library with your household via iCloud — no extra account, no third-party service. Everyone sees what's in the collection and who has borrowed what. Included in LeanBooks Plus.
