In November last year, Google announced an App for the Android system called Google Shopper. The app was downloaded over a million times to Androids and today that number will grow, as it becomes available for your iPhone.
Google Shopper helps you find information on millions of products. Google Shopper recognizes products by cover art, barcode, voice and text search. You can find local and online prices, reviews, specifications, videos, and more to help you make the best purchasing decision. With one click you can save items to your shopping list and share with your friends.
Google Shopper is available for free in the Apple App Store. The App is compatible with the iPhone 3GS and iPhone 4 with iOS 4.0+.
