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
