ShelfCheck Pro vs Kode

Never buy the same book twice. ShelfCheck is the fastest way to check if you already own a book before you buy it. Just point your iPhone at the barcode, and in under a second you get a clear answer: red for owned, green for new, amber for a possible different edition. Built for book collectors, avid readers, and anyone who has ever come home from a bookstore only to realize they already had that book on the shelf.
