At its most basic level, Google Shopper is a price comparison tool for Google Android phones. You can search for products by text, voice, or by scanning a barcode and Shopper will let you know where you can buy the item online or in a local store and how much it will cost you.
But that’s just the tip of the iceberg, because Shopper also features product reviews, history (for keeping track of the items you lookup, and in the latest version Google has also added related products and YouTube product videos.
You won’t find related products or videos for every item you look up. But when they’re available, videos can definitely give you a better sense of whether you really want to plunk down cash on that particular item, while the related product links will help you find alternatives. For instance, when I searched for the Eee PC 1005PE netbook, Google showed me listings for several other netbooks from Asus, Acer, and HP, with the average reviews and prices listed in the details.
Google Shopper is a free app that’s available for all versions of Android, but you’ll need to be in the US or UK to find relevant product listings.
