Google has recently announced another Google made app for Android. This app is called Google Shopper. Shopper lets you find product information quickly by using your phone's camera. This app is similar to Barcode Scanner and Shopsavvy. So if you are familiar with those apps you can jump right in and feel right at home. If you are not it is a very easy and intuitive program to learn.
This app allows you to take a picture of books, CDs, DVDs, and video games, along with most barcodes and it will find the item for you and give reviewer information. It also takes advantage of Google's powerful voice search feature and allows you to say the name of the product and it will find it for you. Google Shopper also logs your history so you'll always have product and price information at your fingertips, even when you don't have a signal. Here's a video demo and the qr code follows.
