MPGraph

Minimal and easy app for the casual tracking and graphing of your car's mileage and fuel-efficiency.

From the 'Home' screen of the app, simply input your start mileage, end mileage, the number of gallons you filled your tank with and hit submit. Your end mileage is automatically moved to the start mileage for your next entry. You can think of any data here as in 'Draft' form, meaning you can enter the start mileage for an entry and come back later to enter the end mileage and gallons used.

From the 'Mileage Entries' screen, view all of your entries chronologically, and if you need, swipe left or right to delete the entry.

Lastly, from the 'Graph' screen, view your fuel-efficiency over time graphed.
