Red Laser is a very useful ap
I was in a marine store and was looking at a new compass for the boat. I found the one I want and the price looked good. You click red laser, and it reads the bar-code using the cell phones camera. You hear a beep when it acquires just like at the checkout stand. Then tells you about the item and its cost. But then using the GPS is knows where you are and then finds the exact item in other nearby stores and lists the price. The stores are arranged by nearest distance. It also has a tab for online retailers as well. Within 20 seconds I found out that I could save 30 bucks buy walking across the street to a retailer there who had 3 in stock! Or I could save 37 dollars by getting it online. pretty useful.
