At last, after having been waiting a while, the owners of an iPhone can download and use the application ShopSavvy, a barcode scanner.
With the help of this application, we can find the best prices on the internet and the nearest shops which sell the products we are most interested.
To use the application ShopSavvy, nothing as simple as pointing the camera viewfinder of our iPhone on a bar code that accepts the standard UPC, EAN or ISBN.
After you start with scaning, ShopSavvy will immediately show all the shops where we can find the product and displays a comparative price list they have for that item in different stores online and offline.
If you choose the physical store which can be called directly, you can activate the GPS-distance and route to get there.
ShopSavvy can works both in the first generation iPhone and the 3G and the 3GS from the iphone apps store introduction.
I've downloaded it with no problem, but does not work in the iPhone 3G. Perhaps the problem lies with the camera, since it does not focus at all well, and it's impossible to tell how many stripes are there and the thickness of these.
Maybe it work well in Iphone 3GS.
