You bought an Android phone because you’re into cool functionality, right? Don’t attempt to deny it, something that creates a database of your books, CDs, DVDs and video games is exactly the kind of thing you like.
Here we have Shelves. Putting to use your phone’s camera, Shelves scans the barcodes of your collections and automagically creates a virtual representation of them on your phone, for cataloguing, loaning, or just admiring.
Shelves purports to recognize a whole host of item types, seemingly nearly everything that isn’t food. All modes operate identically - you select 'Scan' from the pop-up menu, and point your phone’s camera at the barcode of your item.
