GasBuddy is built for Android and iPhone. The app tells you the location of the nearest gas station and which has the best prices in the 'hood. It relies on user-submitted information, so some information may be dated, but our listeners say even when information is not up to the minute GasBuddy still gives them a ballpark idea of what gas should cost in the area.
What Car Talk visitors say:
"By far, my favorite car related app is GasBuddy. This is a great way of sparing yourself the pain of, "Oh, darn, the next station around the corner was ten cents cheaper," after you've already filled up! -- Ash.
