This is the second foray into iPhone territory by Consumer Reports. The first app pretty much duplicated the currently-available online content, and was free. This second app, called Consumer Reports Mobile Shopper is US $9.99, and puts the impeccable brand and product reviews in a more iOS-specific form.
The app allows you to browse through CR ratings of thousands of products, and allows searches by brand name or model. You can also scan the UPC bar-code using the iPhone's camera. The app also gives you best prices both online and locally using PriceGrab
