Guzzler is an app for managing fuel that does all the math for you.

There are applications already on the mobile phone market that can find inexpensive gas based on location. There are yet others that can use the GPS now available in many smart phones to help you drive more efficiently. Although they help you save gas, these apps only show the posted cost of gas nearby or show possible routes. What's the true cost? If you travel out of your way to a cheap station, are you really saving any money? They leave answering these questions up to you.

Guzzler is the Answer

Guzzler will provide the true savings feature still missing in other gas purchase apps. By rating which stations provide real savings and recording each trip you take after you shake [your phone to let Guzzler know you want to record a car trip] for comparison, you can always make the better choice. Guzzler will know about your car too, to calculate your actual mileage between purchases. When you purchase gas, just tell Guzzler and all the calculations happen in the background. At the end of the month you’ll see how much gas you purchased for each vehicle, and how much you spent. Guzzler will award you points based on your performance, which you can improve by carpooling too. Via your Guzzler account you can then spend your points in the form of donations to eco-friendly charity.

The Routes Section

	The Find Gas section is the heart and soul of Guzzler. Here a map shows you nearby gas stations and routes to them based on your current location. These are already evaluated for you for true savings in the currently selected car. You can select the route you want in the main menu, or by tapping it in the map. A Guzzler Avatar shows you how your choice affects your Guzzler standing.
	Pressing the Gas Purchase button in the bottom left opens of a short form where you record your gas purchases. The purchase is always assigned to the currently selected vehicle, which you select in the Preferences -- Car Data section.
	In the Plan Trip section you can plan a trip to a specific destination, and ask Guzzler to help you find gas when you're tank will be approximately 1/4, 1/2, or 3/4 full.
	In the Route History you view a list of the routes you've recently taken, or search for specific routes based on an address or location.

The Stats Section

The Stats section is the part of the application that shows you your driving statistics. Every time you record a trip or gas purchase with Guzzler, the data is collected and analyzed to help guide your driving and gas purchase choices. The Guzzler Avatar's appearance for sharing with Facebook or Twitter, and your awarded Guzzler points for charitable spending, are based on these calculations too. The stats section gives you an overview of gas use, mileage, and Guzzler points.

	The Gas Use section is where you can review gas use in the selected car for the past week, month, and year.
	The Mileage section will show you how many miles (or kilometers, depending on your setting in Preferences -- General Settings) you've recorded for the selected car in the past week, the past month, an the past year.
	The Guzzler Points section provides you with graphs for an overview of how many points you've earned in the past week, month, and year. Here's also where you can see the current appearance of your Guzzler Avatar for the selected car.

Javascript charts and graphs were created with the free to use framework, RGraph.
