Made for Android. Made for iPhone.
Fuelio is two native apps that follow each platform's design, so they look a little different and a few features differ.
Android
Android Auto on the car's screen, trips that start when the phone connects to your car's Bluetooth, a home screen shortcut for quick fill-ups, and backups to Google Drive or Dropbox.
iOS
CarPlay with nearby gas prices, automatic trip recording and Live Activities, Home Screen widgets, six color themes and iCloud Drive backup.

Drivers love Fuelio
Fantastic app - free, no ads, powerful/customizable yet simple and usable, no bloat. Syncs to other devices as well as backups automatically to either Google Drive or DropBox. Has replaced my paper-based petrol log-book.Best mileage app out there! Installed this when I purchased my new car in 2013. Had allowed me to track fuel consumption and prices for all 25k miles. Frequent updates, constant improvement. Highly recommend!Now THIS is what I've been looking for! I'm just a gal who wants to easily track gas costs, miles, etc. without having to spend a bunch of time punching in info. This app is simple, effective, to the point and attractive. BRAVO!!Best fuel app out there. I like how it allows me to backup the information to my Google Drive for recovery purposes. My phone died and was replaced recently and I was able to get back all of the data and continue on.Best app I've found for tracking MPG. Also like the features like reminders to remind me of oil changes and maintenance. And also the ability to backup. Useful app!Excellent! Use to log all vehicle purchases so that I have a full history if I resell. The stats page is useful for showing just how expensive cars really are to run!Great app. I am using this since 2014. You can monitor fuel consumption, monthly expenditure for your vehicle. It has improved a lot during last couple of years.I love keeping track of my fuel economy and other car expenses. Easy to use. Great reports. Love it.Our story

Common questions
How do I calculate my car's MPG?
Fill the tank to full and note the odometer. At the next full fill-up, divide the miles driven by the gallons you just added. Fuelio does this for every fill-up and also handles partial fill-ups.
Learn more →How is fuel consumption in l/100 km calculated?
Divide the liters used by the kilometers driven and multiply by 100. For example, 42 liters over 600 km is 7.0 l/100 km. Fuelio can show l/100 km, km/l or MPG.
Learn more →How do I work out how much fuel a trip will cost?
Divide the trip distance by your car's fuel economy to get the fuel needed, then multiply by the price per gallon or liter. Use your real consumption from past fill-ups, not the manufacturer's figure.
Learn more →What is the best way to track car expenses?
Record every cost with its date, odometer reading and a category such as service, insurance or parking. An app keeps the totals and charts for you, and a CSV export gives you a spreadsheet when you need one.
Learn more →How much does my car cost per mile?
Add up everything you spent on the car in a year (fuel, insurance, service, tax, parking) and divide by the miles you drove. Fuelio shows your fuel cost per mile or kilometer from your own fill-ups, and the Cost of Ownership report adds everything else.
Learn more →Can I track LPG and gasoline separately in a bi-fuel car?
Yes. Set the vehicle up as bi-fuel with two tanks, then choose the tank at each fill-up. Fuelio then tracks the LPG (or CNG) tank and the gasoline tank separately.
Learn more →How do I remember when my next oil change is due?
Set a reminder by mileage, by date, or both, whichever comes first. Fuelio checks it against the latest odometer reading from your fill-ups and costs.
Learn more →How can I find cheaper gas near me?
Compare prices on a map before you drive, check the average for your area, and fill up where you already pass by. Fuelio shows station prices from official sources and from other drivers.
Learn more →Is there a Fuelio web version?
No. Fuelio is a native app for Android and iPhone only, so there is no website to log in to and no account. The iPhone app also runs on a Mac, and we are still improving it for desktop screens. Your data stays on your phone, and you can export it as a CSV file.
Is Fuelio free?
Yes. Fuelio is free to download and use, and the free version is fully usable, with no ads and no account. Backup, export and import are free too. Some extras are part of an optional Premium upgrade, which the app shows you.
