There's an app for your smartphone that you may want to get. It's not as fun as, say, Angry Birds but it could save you money. Smartphone apps like Gas Buddy may end up being the year's most popular. It's one where the user can check for the cheapest prices in any given area.
"Crowd sourcing means people like you who have the app installed, when you go to a gas station while you're filling up, you say 'I got a second or two, I'll enter the gas prices at this gas station,' and then everyone else can see that information," said Brian Cooley, editor of CNET.com.
Apple's app for the iPhone is called "Fuel Finder" but relies on Gas Buddy for its information.
"But I think the real value here is that you're going to get a very community oriented take on where the cheapest gas is in a way that only thousands of real eyeballs in the street could ever do," said Cooley.
