Fillnote: Fuel Log & MPG

Log a fill-up in 3 seconds and see your real fuel economy. No sign-up, no subscription wall, no cloud account — your car log stays on your phone, and backups cost nothing.

WHY FILLNOTE

Other fuel log apps moved backup and sync behind a yearly subscription, or make you create an account before you can log a single fill-up. Fillnote opens straight to your car. Type two numbers and you are done.

FUEL LOG IN 3 SECONDS

• Enter any two of total cost, price per gallon/liter and volume — the third is calculated for you

• Decimals are fine (41.22 L, 10.8 gal), and last price is pre-filled

• Full tank or partial fill-up, with notes and gas station

• Log past fill-ups on any date — no "must be in order" errors

REAL MPG, NOT A GUESS

• Fuel economy measured full tank to full tank, partial fills included

• MPG, km/L or L/100km, US or UK gallons, per vehicle

• Cost per mile/km and fuel spend this month on the home screen

NEXT SERVICE, WHICHEVER COMES FIRST

• Oil change, tire rotation, air filter, inspection, insurance — ready to use

• Set an interval by distance, by days, or both

• Home shows "Engine oil in 780 mi" so you never have to do the math

• A reminder notification only when something is due soon

EVERY CAR EXPENSE

• Fuel, service and other expenses (parking, wash, tolls, tax) in one log

• Monthly totals, fuel economy trend chart and spend by month

• Multiple vehicles, each with its own units

YOUR DATA, YOUR FILE

• Save a backup file anywhere you like and restore it on a new phone — no subscription needed

• Export CSV to Excel or Google Sheets

• Dark mode for night drivers
