Google today updated its Shopper app for iPhone with the ability to browse nearby offers provided by the Google Offers local deals service, which is available only in select U.S. cities. What’s more, you can purchase deals (discounted up to 50 percent) and subscribe to offers for your city, both from within the app. Google Shopper is a free download for iPhone and iPod touch from the App Store. The Shopper app launched on iPhone in February, enabling users to scan product bar codes or search for product information using voice or text. The app serves local and online prices, reviews, specifications, videos, and more. Google also issued an update to its Google+ native client for iOS yesterday, adding full resolution photo uploads, search and photos +1s.
