Favourite Shopping apps for your Smartphone

ShopSavvy is one of the most polished shopping apps I came across, and it's 
available for both iOS and Android. Scan any bar code and find online stores 
and nearby retailers selling any particular product, along with competing prices 
from all locations. ShopSavvy can calculate the location of the nearest retailers 
carrying a desired item and provide maps and directions. It can also tell you 
whether or not the product is actually in stock at a given location. Additionally,
there's a Deals feature that offers up shipping promos, coupon codes, rebates,
and weekend sales.

Barcode Hero is an iOS app that lets you use the camera of the iPhone or iPod Touch

to scan the bar codes of products that you see on store shelves. It then provides 

instant recommendations, product details, and price comparisons from a variety of 

online and brick-and-mortar retailers.In addition to the scanning functionality, 

you can browse and search for products by category, share items with friends 

or family to get real-time feedback, and share wish lists. You can also save 

items as a reminder to purchase at a later time.

If you want to take the stress out of shopping for the handymen (or -women) 

in your life, Aisle411 is a great place to start. This feature-packed and 

easy-to-use app is designed to help you navigate large retail locations, 

such as Home Depot and Lowe's.The app has many functions, but what stands 

out are its list and location features.

TheFind's Beat This Price app for iOS lets you search for a particular item at a given 

price and then populates a list of competing prices from other vendors. It also uses 

LBS to help you find the nearest retailer selling the product.
