Saving as much as you can on gas has never been more of an issue for drivers, and thanks to GasBag you can easily find the station with the lowest price around with a few taps of the finger. 

GasBag is a free application which uses the GPS receiver in an iPhone 3G, or any manually-entered address, to search gas prices for nearby service stations.  It then displays the data in bubbles over a street map.  Click a station and you’re provided with the station’s address and a detailed list of their price per gallon for different grades of unleaded gasoline and diesel; you can also get driving directions in the iPhone’s Maps software. 

The pricing data is user driven, which is a downside given that data is only available for stations about which iPhone users have posted.  It would be far more effective if it used existing gas price databases, but it’s certainly a worthy addition to your iPhone.
