GoCart informs the shopper. It bridges the gap that exists between shopping online and shopping at the store. GoCart is your shopping cart on-the-go. Users can scan the barcode of any product using their phone’s built-in camera. Once scanned, it will search for all the best prices on the internet and through the inventories of nearby, local stores. After scanning a product, users can also read online reviews or even create price alerts to help monitor price drops. Also, organize the products you’ve scanned into wish lists that can be shared with your friends on your social networking profile page.

Scan the barcode of any product using Android’s built-in camera, GPS and location aware features to search for the best prices from both online and nearby, local stores.

Wish lists will help you stay organized. Save the products you’ve scanned into categories you define. Build a list for brainstorming gift ideas for the holiday season. Build another list for your own wedding registry. Any list can be shared with your friends on your social networking profile page using Google’s OpenSocial API.

Price alerts will inform you when the price of a particular product drops within your range. Get these alerts sent directly to your phone’s email inbox. If it’s from a local store use the Android phone to call the store directly or even get directions using Android’s built-in mapping application. If it’s being sold online, use the web browser to buy right from your phone or even email the link to a friend.
