Amazon's ( AMZN) Price Check
While Amazon's Price Check app became available for Android users in mid-November, it's been on iOS since 2010. Just like the Apple app, Price Check for Android is incredibly simple to use. You can scan an item using its barcode, snap a picture of it with your phone's camera or speak the name of the item and the app will pull up the product from Amazon's Web site complete with prices, a description and reviews. If you find a product you like, you can buy it directly through the app using your Amazon account.
