Everything you own. Everywhere it is. Everything in it.
Call Number is a personal library catalog for the books you actually own. Photograph a shelf and it reads the spines, identifies every title, and remembers exactly where each one lives — which room, which bookcase, which shelf.
Photograph a whole bookcase and Call Number reads the spines — or scan a barcode, or search by title.
Granular locations across buildings, rooms, bookcases and shelves. Never lose a book again.
“Which of my books cover rose care?” Get grounded recommendations from the shelves you already own.
One library, shared with your household — everyone sees the same catalog, in sync.
