I tried the Red Laser Barcode & QR Scanner:
This was interesting to use as you can scan a barcode on a product, which than will do a price comparison finding the best local deal. We go through alot of pop at my house. So it was interesting to scan the barcode on my can of pop which gave me the best price and its location for my area.
WIFI Finder:
This works good, especially if you're at a location that isn't familiar to you.
I used this when we were on a trip & needed wifi this was quick and easy to use.
