Google has launched a new app for Android users by the name of Google Shopper. This app is somewhat an extended and much refined version of Google Goggles.
What Android users will be able to do is to search for products just by scanning them, their bar code or any other identification mark and Google will provide them with details on price, availability, reviews, etc.
This is a neat application but would be beneficial in countries where online shopping is pretty much part of day to day activities.
Here's a video by Google demonstrating how the app works. It is available through Android Market Place on Android based handsets.
