Log fill-ups, see your real MPG and what fuel actually costs you.
Read full description
Know your real gas mileage, not the number on the sticker.
Gas Mileage Tracker is a fuel tracker for people who want to know what their car actually does. Log a fill-up in about ten seconds and the app works out your real MPG, your cost per mile, and how far you land from the official EPA rating for your exact model.
WHAT IT DOES
Real gas mileage, tank by tank
Enter the odometer, the volume and the price. The app calculates MPG from full tank to full tank, the way it should be done: it adds up the distance and the fuel and then divides, instead of averaging a column of numbers.
Your car against its EPA rating
Match your car once, by year, make, model and trim, and the app pulls the official combined rating from fueleconomy.gov. From then on every average is shown against the sticker, with what the gap costs you over a year of driving. Most cars land below it. Now you know by how much, and whether it is normal.
A real fuel calculator
Cost per mile, spend this month, total spent, and the price per gallon you have actually been paying over time. Three charts, no clutter.
Your units and your currency
Miles and gallons, litres and kilometres, or miles with litres and imperial MPG. Pick your country when you start and change it whenever you want. A gas mileage tracker that only speaks US gallons is useless in Canada, the UK or Europe, so this one does not.
Every car in the garage
Each vehicle keeps its own history, its own averages and its own EPA rating.
Fill-up history you can edit
The complete fuel log, correctable when you fat-finger a digit at the pump.
Export to CSV
Your whole log as a spreadsheet, for taxes, expense reports or your own records. Always in miles and gallons so the file stays comparable.
Dark mode throughout.
WHO IT IS FOR
People watching a budget, people claiming business mileage, and people who just want to know whether that new air filter did anything. If you have ever done the gas mileage calculation on your phone's calculator at the pump, this is that, remembered.
NO ACCOUNT, NO ADS
There is no sign-up. Your fuel log stays on your phone.
Gas Mileage Tracker is free. A one-time purchase unlocks CSV export, unlimited vehicles and the full statistics.
