Point your camera at any book's barcode and instantly see all your options: read it, listen to it, or find it nearby with the best price. No more switching between apps to compare e-book, audiobook, and print costs — one scan does it all.
Target Customer
Avid readers, commuters, and bargain-hunters who browse physical books (in stores, libraries, friends' shelves) and want the fastest way to get the version they prefer — digital or physical — at the best price.
