WASHINGTON - Pain at the pump? There are definitely some apps for that.
Several free iPhone apps can help you find cheap gas close to you based on your GPS location, and you can have the information presented to you in a number of ways.
One app, simply called "Local Gas Prices," gives you a list sorted by either price or location. The app called "Cheap Gas" gives you a list of best prices, and you can click on a price to get the station location.
The app ranked best by mashable.com is called "GasBuddy." It lets you sort options by fuel grade and links you to dedicated pages for stations you choose.
The app is also available on Android and Windows 7 smartphones.
