With iExit Gas, you can quickly find the cheapest gas station at each interstate exit. We've combined GasBuddy fuel prices with the US highway system to create "GasBuddy for the Interstate".

iExit Gas supports Unleaded, Mid Grade, Premium, and Diesel prices. When you buy it, you are buying LIFETIME access to iExit Gas and will never be charged a subscription. It will pay for itself immediately, possibly on the first time you use it!

How to use:

If you open up iExit Gas on any US exit-based highway, it will automatically switch into "On Highway" mode and displays upcoming exits ahead, with the cheapest gas station highlighted at each exit. Select an exit to see all stations at that exit, or select a station to see its details, or to call or get directions.

If you're near a highway but not driving on it, you can still select "Find Me On Highway" and simulate your upcoming drive. Or if you're on the couch and nowhere near the highway you want to look up, simply select "Lookup Any Highway" and search for any highway by state.

iExit Gas is a child of the highly popular app, iExit, but specializes in highlighting the cheapest gas at each exit. There are lots of gas price apps out there, but this is the only one that tells you what you really want to know: What exit should I get off to get the cheapest gas?
