I’ve found RedLaser is the best app for comparing product prices. It also delivers food nutrition and allergen info, finds library books and more.

RedLaser uses your smart phone’s camera to scan the barcode of products that you might buy. It then hits the Internet to pull down a list of prices so you can see if you’re getting a good deal. Better price online?

Then, with a few taps, RedLaser lets you jump to a merchant’s online site to close the deal or e-mail yourself the details if you prefer to do your online shopping from a desktop.
