This is probably the best barcode scanner not only on Android, but on iPhone as well.
I just love this app, seriously. It is certainly a must for every owner of any modern mobile device, especially the Android ones, because it provides the easiest way of getting new apps and games directly from review websites like feedandroid.com — by scanning a QR-code linked to market address.
But the primary function of this app is even better. Using ShopSavvy you can scan almost every barcode and get not only the info and image of an object it belongs to, but the list of web and local prices, including best (lowest) ones. So you can go the store, pick something, scan its barcode, check if this item’s price here is fair and if not and then just proceed to the nearest place where you can buy it for less money.
Among with brilliant design and great touchscreen interface, these are the main advantages of the ShopSavvy Barcode Scanner. But nothing is perfect in this world, so it doesn’t work flawlessly all the time. It may show you old prices or scan barcode incorrectly and bring up irrelevant product, though this cases are very rare. What I would like to see as an improvement is the quality of images it gets from internet, because often they are very low-res and look bad on our huge HD screens. And possibility of moving data to SD card would be nice as well.
