Read full description

Cozyshelf is a calm, private home for every book you own, lend, borrow and read. Point your camera at a cover, and Cozyshelf recognises the book, then fills in the title, author and publisher for you. If a cover is worn or unusual, scanning the barcode works just as well. Nothing stops you from typing a book in by hand either. YOUR SHELF • Add books by cover photo, barcode or by hand • Track reading status: not started, reading, finished • Rate books and keep as many notes per book as you like • Organise by author, genre and publisher • Search and filter your whole collection instantly LENT AND BORROWED • Record who you lent a book to, so you actually get it back • Keep track of books you borrowed from someone else • See at a glance what is on your shelf and what is out on loan READING STATISTICS • Books finished this month, this year, and your monthly average • Breakdowns by author, genre and publisher • Read-through rate across your collection • How far you range beyond your usual authors and genres PRIVATE BY DESIGN There is no account to create and nothing to sign in to. Your books, notes and cover photos are stored on your device and stay there. No cloud sync, no analytics, no trackers, no advertising. When you look up a book, only the title and author text — or the ISBN — is sent, never your photos or your library. ALSO INSIDE • Backup and restore your collection to a file you control • Optional local reading reminders • Light and dark themes Cozyshelf works offline. Your shelf belongs to you.
