About

Koob is your home library, made digital. Put your real bookcases on your phone, collect your reading life in stamps and notes, and help build a book catalog made by readers. It all runs on your device, so it keeps working with no signal at all. YOUR SHELVES, MADE DIGITAL • Scan an ISBN barcode and the book lands on its shelf, with cover, author and details filled in automatically • Build bookcases and shelves that mirror your home: the office, the bedroom, the pile by the bed • Moving from Goodreads? Drop in your CSV export, we match your books by ISBN, and you shelve them with a live preview • Mark every book as To read, Reading, Read or Did not finish, and find any title at a glance • No signal on the metro, in the stacks or on a plane? Your shelves glow on. Browse, shelve, take notes and log your reading as always A READING LIFE YOU COLLECT • Your milestones are issued as stamps in a collector's album, one series to a page. Each series climbs from bronze through silver, gold and platinum to diamond, and you watch the next tier ink in as you read toward it • Every month you finish books in is bound into a volume you can keep • Keep the quotes and thoughts you want to remember, private to you • Set a yearly goal in books or pages, log your reading sessions, and see in your reading stats whether you're ahead or behind • Rate and review the books you finish READ WITH FRIENDS Add friends and start a reading challenge: race to the last page, read the same book together, guess the book from its cover, or solve a riddle hunt. A LIBRARY BUILT BY READERS Koob's catalog grows with the people who read from it. When a book is missing, add it: scan the spine, snap the cover, fill in what you know. Once a reviewer accepts it, it's in the catalog for good, and every reader who comes looking for it finds it because of you. That includes the local and older editions that are hard to find elsewhere. EARN TOKENS, SPEND THEM ON WHAT YOU NEED Accepted books earn tokens, with a bonus for a spine photo. Fix a typo, add a missing cover, complete an entry: accepted fixes earn tokens too. Prefer not to contribute? Watch an optional ad for free tokens every day. Spend them on Super Search, which digs past our shelves for rare editions and obscure printings, or on Koob+ months. FREE, WITH KOOB+ WHEN YOU WANT MORE Koob is free to use, with no forced ads: the only ads are optional ones you watch for free tokens. Koob+ adds: • Sync across all your devices, so the library you build on one is waiting on the next • A monthly token allowance for Super Search • Scanning a whole stack of books in one go • Special stamp series for your books, your genres and your bookcases • Unlimited private challenges with friends Every book you add helps the next reader.
