The Google Shopper app for mobile devices helps users discover products, compare prices, and make purchasing decisions. Google Shopper for mobile lets users compare brick and mortar prices with online prices, read product reviews from other shoppers, and examine detailed product specs.
For users looking for shopping ideas, Google Shopper has a Nearby Offers tab that lists nearby offers that businesses in the area have submitted through Google Places. Google's mobile shopping app also contains a Today’s Offer tab that features new deals made available by Google Offers. Those offers can be purchased and saved in the My Offers tab for convenient use. My Offers holds deals purchased through Google Offers or Google Offer Ad Extensions.
Google Shopper for Android vs. iPhone
There is a Google Shopper android app and a separate Google Shopper iPhone app, very few differences between the two. Download Google Shopper at the Google Play store or the iPhone App store.
