Built for the pump, not the spreadsheet

Stop guessing what your car costs.

The dashboard's "average economy" resets when you're not looking, and receipts fade in the glovebox. Fuel keeps an honest log and does the arithmetic, so you know what your car actually costs to run.

Log a fill-up

Fifteen seconds at the pump. Then drive off.

Odometer, fuel, price. Fuel fills in the total, remembers the last price you paid, and shows your previous odometer reading so a typo can't sneak into your numbers.

Enter any two of amount, price, and total, and Fuel works out the third.

Decimal keypadAuto totalFull / partial tankNotes
Real fuel economy

Your real MPG. Not the number on the window sticker.

Every full tank becomes a data point. See average, best, and worst economy, total fuel, total spend, and cost per mile, for the last 10 fill-ups, 30 days, 90 days, or all time.

Only topped off halfway? Partial fills carry forward into the next full tank, so a quick splash never skews your numbers.

MPG = miles since last full tank ÷ gallons added

History with a summary card and fill-ups grouped by month, with an amber badge on a partial fill
Settings with US MPG, UK MPG and Metric L/100km unit options, and a Data Not Collected privacy note
Every car, every unit

Five cars. Three unit systems. One tap to switch.

Keep the commuter, the truck, and the weekend car apart, each with its own history and stats. Pick US MPG, UK MPG, or L/100km, where lower is better and Fuel knows it.

Switching units changes what you see, never the data you stored.

CSV export

Your whole log in a spreadsheet, in one tap.

Export every fill-up for a vehicle: date, odometer, fuel, price, cost, economy, full or partial, and your notes. Then AirDrop it, mail it, or save it to Files.

Made for expense reports, mileage deductions, and fleet logs, or just a pivot table on a rainy Sunday.

Price memory
It remembers what you paid
Your last price per gallon or litre is already filled in. At the same station, logging is just the odometer and the amount.
Partial fills
Handled the right way
A partial fill is marked in amber and folded into the next full tank, the standard method for accurate economy.
L/100km
Knows lower is better
Best and worst flip correctly in metric, and numbers are formatted the way your region writes them.

Questions from the forecourt

How does Fuel handle partial fills?
Switch off "Full Tank" when you log. Fuel carries that fuel forward to your next full-tank fill-up and calculates economy over the combined distance, which is the standard way to get accurate numbers.
Which units does it support?
US MPG (miles and US gallons), UK MPG (miles and litres, shown as imperial MPG), and metric L/100km. Switch anytime in Settings. Your stored entries are never converted or modified.
Can I track more than one car?
Yes, up to five vehicles, each with its own fill-up history, stats, and CSV export.
Where is my data stored?
On your device, and nowhere else. No account, no cloud, no analytics. The App Store privacy label reads "Data Not Collected." Export to CSV whenever you want a copy.
What do I need to run it?
An iPhone or iPad running iOS 17 or later.
Is $2.99 really the whole price?
Yes. One purchase, every feature, every future update. No subscription, no in-app purchases, no ads.

Your next fill-up is data point number one.

Log it at the pump. Fuel takes it from there.
