iGasUp: Find Cheap Gas

While the price of gas has been dropping from $4.00 down towards $3.00 in recent weeks, I still pay attention to which stations offer lower prices when I go to fillup. I’ve found differences of up to 20 cents per gallon between stations that are just within a mile or two of my home in Colorado. That savings can add up quickly if you’re careful about where you buy gas.
There are a couple of iPhone apps that attempt to help you find the cheapest gas, wherever you happen to be, by combining pricing information from the internet with the location services of the iPhone. I looked at GasBag, iGasUp, and Where to see which one would help me find cheap gas, particularly when I was in an unfamiliar part of town. In my usage for a week, I found iGasUp to have the most complete and the most current pricing info, even if it was a little glitchy in map mode. It had more stations in my area (Denver, CO) and the pricing was consistently more accurate than the other apps.
