ShopSavvy was one of the best early Android applications. It launched in October of last year after winning one of the initial Android Developer Challenge top prizes (when it was still known as GoCart). But despite the success it has seen on Android, one question remained: When would it be available for the iPhone. Today, it finally is. Developed by the guys at Big In Japan , ShopSavvy is an app that allows you to use your device as a portable barcode scanner. You point your phone's camera at any barcode and it will read it, do a product look up, and give you information about the product, as well as where you can find it online or at nearby stores and for how much. Obviously, something like this is a window shopper's dream.
