Tankstops is a simple program to record your fuel stops. Once you have
entered your vehicle(s) you can start recording. It asks for odometer,
amount of fuel and the amount of money. It doesnt care if you use
liters or gallons, or euros or francs. You can export the data to
CSV files so you can import them in a spreadsheet. You can download
the CSV files to your computer via iTunes or send them to an emailaddress
straight from your phone.
