Tankbook: Fuel Log & MPG

Tankbook is the fuel log that gets the math right and doesn't charge you for it. Log a fill-up in seconds at the pump and see your real mileage for every tank, free, with no account and no signal needed.

LOG A FILL-UP IN SECONDS
• Odometer, gallons or liters, and what you paid: that's it
• Type any two of amount, price and total, and Tankbook works out the third
• Prefer your trip meter? Enter the trip distance instead of the odometer
• Your vehicle is always shown at the top, so you never log to the wrong car

REAL MILEAGE FOR EVERY TANK
• MPG, L/100 km or km/L for each tank, right after you save
• Partial fill-ups are handled properly: they add up until your next full tank
• Forgot to log one? Mark it and that stretch is left out instead of faking a number
• Edit any entry and the tanks around it are recalculated

EXPENSES AND SERVICE REMINDERS
• Track maintenance, repairs, tires, insurance, tax, parking, tolls and more
• Reminders by distance, by date or both: oil change, tire rotation, brakes, inspection, insurance
• One notification on the day a service is due. Nothing else
