In my opinion, Barcode Scanner is the best out of all the "scanning" apps such as Google Shopper, etc, because it instantly loads up to the scanning screens and uses auto focus (I find Google Shopper and others are harder to focus, and you have to click through). When it scans a barcode that it recognizes, it works great. Easy access to the web to compare prices. However, sometimes it does not recognize the bar code for normal stuff, or when it tries to search the bar code on the internet, nothing relevant comes up. All in all, I give it 4/5 stars.
