The best free fuel tracker apps
#1
Fuelio
Best for: full fuel logbook with cost stats
Visit fuel.io
Starting priceFree
Free planYes
Fuelio has been the Android community's favorite fuel log for over a decade, and it is easy to see why. You log each fill-up with the odometer reading, fuel amount and price, and it computes your real fuel economy, cost per mile and monthly spending. It goes beyond fuel too, with cost categories for service, insurance, parking and tolls, plus reminders for oil changes and registration. Everything backs up to Google Drive or Dropbox, so your history survives a phone upgrade.
The app is now part of Sygic and remains free, with a Pro subscription adding deeper analytics. The honest weakness is that it is only as good as your logging habit. Skip two fill-ups and the MPG math gets shaky. If you want the clearest picture of what your car costs to run and you do not mind thirty seconds at the pump, nothing free beats it.
What we like- Detailed consumption and cost charts
- Tracks service, insurance and other car costs
- Backups to Google Drive and Dropbox
Watch out for- Manual entry takes discipline at every fill-up
- The interface shows its age next to newer apps
Starting priceFree
Free planYes
GasBuddy answers a different question from Fuelio: not "what does my car cost" but "where is gas cheapest right now." Its crowd-sourced price maps are the best in North America, with over 100 million downloads behind the data, and the trip cost calculator helps you budget road trips. It also includes a Fuel Logbook for tracking purchases and fuel economy, plus GasBack rewards and a payment card that discounts each gallon.
As a pure tracker it is thinner than the dedicated logbooks, with fewer charts and no service reminders. But most drivers save more by paying less per gallon than by analyzing their MPG, and GasBuddy is unmatched at the first job. Use it for prices and the logbook for basics, or pair it with Fuelio if you want both.
What we like- Crowd-sourced price maps cover the US and Canada
- Fuel Logbook tracks economy in the app
- Pay with GasBuddy+ card adds per-gallon savings
Watch out for- Price data quality varies by area
- It is a price finder first, a logbook second
Starting priceFree
Free planYes
Fuelly does one thing and does it well: it tracks your gas mileage over time and shows you what it costs. Logging is deliberately minimal, add the vehicle once, then record each fill-up by web, mobile app or even SMS. The payoff is the community data. With over 16 billion miles tracked, you can look up the real-world MPG of your exact car before you buy it, which no spec sheet gives you.
There are no cost categories, no reminders and no fancy charts, and the site looks like it has not changed in years. That is the trade-off for a free tool with no upsell pressure on the core feature. If you want the simplest possible answer to "what mileage am I actually getting," Fuelly is it.
What we like- Dead simple fill-up logging by web, app or SMS
- Huge community database of real-world MPG by vehicle
- Free with no paywall on core tracking
Watch out for- Dated interface and basic charts
- No service reminders or expense categories
Starting priceFree
Free planYes
Drivvo is Fuelio's closest rival and the better pick outside the US. It logs fill-ups, expenses and services, then answers the question most trackers dodge: what does this vehicle cost you per kilometer and per month. The gas station maps span more than 190 countries with hundreds of thousands of crowd-sourced prices, and the whole app is localized into 79 languages. A web dashboard and fleet tools make it viable for small businesses running several vehicles.
The free tier covers the essentials, with 4.2 million vehicles tracked on the platform, but expect prompts to upgrade for the deeper reports. For drivers in Brazil, Europe, Asia or anywhere Fuelio's price data is thin, Drivvo's coverage wins. Either way, pick one logbook and stick with it, because two half-filled trackers are worse than one complete one.
What we like- Cost-per-km and per-month math done automatically
- Gas price maps in 190+ countries
- Works in 79 languages with fleet features
Watch out for- The free app nudges you toward the paid tier
- Some advanced reports need the upgrade
Starting priceFree
Free planYes
MileIQ belongs in a different category from the logbooks above, and that distinction matters. It does not care about your MPG. It automatically detects every drive, lets you swipe right for business and left for personal, and builds the mileage log your accountant wants at tax time. With over 100 billion miles logged, it is the most proven automatic tracker available.
The free tier covers 40 drives a month, which suits a light business driver but not a courier. If your goal is maximizing the mileage deduction or getting reimbursed, MileIQ is the right tool. If your goal is understanding fuel costs, it is the wrong one. Many small business owners run MileIQ for taxes and Fuelio for costs, which is a sensible free combination.
What we like- Automatic drive detection with swipe classification
- IRS-compliant reports export in one tap
- 1M+ active users and 80,000+ five-star reviews
Watch out for- It tracks miles, not fuel, so pair it with a logbook
- The free tier caps at 40 drives per month

Everlance is MileIQ's main rival with a broader brief. It tracks miles automatically like MileIQ, but it also syncs your credit cards and bank accounts to log expenses, scans transactions for missed deductions, and manages receipt photos. For a rideshare driver or freelancer, that combination replaces two or three apps. It claims over 4 million drivers and a 4.8-star rating across tens of thousands of reviews.
The free trial lets you test the full automation, but the ongoing free tier is limited, and this much machinery is overkill if you just want MPG numbers. Pick Everlance when your car is a business tool and the tax deduction matters more than the fuel chart. For pure fuel tracking, the logbooks above do more for less.
What we like- Automatic mileage and expense tracking in one app
- Bank and card sync for expenses
- IRS-compliant reports across devices
Watch out for- The best automation sits behind the paid plan
- More app than a casual driver needs
Starting priceFree
Free planYes
TripLog is the power user's mileage tracker. Beyond automatic trip detection, it handles expense reports with receipt scanning, time tracking for mobile workers, and integrations with QuickBooks and GPS hardware like its MagicTrip beacon. Teams can manage reimbursements for a whole mobile workforce from one dashboard. The free Lite plan covers manual trip and expense tracking with a cap on report entries.
For a solo driver who just wants fuel economy, this is too much app. For a small business with people on the road, it replaces a mileage tracker, an expense tool and a time clock. The fuel expense features are a bonus rather than the point, so judge it on the reimbursement workflow, not the MPG chart.
What we like- Mileage, expense and time tracking in a single app
- GPS auto-start options including beacons
- QuickBooks integration for reimbursement
Watch out for- The free Lite plan caps report entries
- The interface is built for fleets, not casual drivers
Starting priceFree
Free planYes
Simply Auto is the dark horse of this list. Its free tier is unusually generous: unlimited fill-ups, services and expenses, in-depth reports, voice-activated input, service reminders and up to four vehicles, all for $0. The paid tiers are cheap by any standard, with Gold at a $9.99 one-time payment adding cloud backup and receipt capture, and Platinum at $9.99 per year adding unlimited vehicles and drivers.
The catch is that automatic trip logging is capped at 15 trips a month on the free tier, and the user community is smaller than Fuelio's, so there is less crowd wisdom to lean on. But as a pure car-management logbook, the free version does more than most competitors' paid ones. If you want one app for fuel, maintenance and costs without paying, start here.
What we like- Free tier includes unlimited fill-ups and up to 4 vehicles
- Voice input and service reminders
- Gold is a $9.99 one-time payment
Watch out for- Automatic trip logging is limited on the free tier
- Smaller community than Fuelio or Drivvo

Driversnote rounds out the mileage-tracker half of this list. It automatically logs your trips, classifies them intelligently, and produces the compliant mileage report you hand to your employer or accountant. An iBeacon option in the car makes detection more accurate and saves phone battery, a thoughtful touch for heavy drivers. The app holds a 4.7 rating across more than 100,000 reviews.
Like MileIQ, it has nothing to say about your MPG or fuel spending, so do not install it expecting a fuel logbook. It earns its place because so many people searching for a fuel tracker actually need a mileage log for work. If that is you, Driversnote is one of the cleanest options, with a free trial to prove it on your real driving week.
What we like- Clean automatic trip logging with smart classification
- One-tap IRS-compliant reports
- Highly rated with 100,000+ app reviews
Watch out for- No fuel consumption tracking at all
- Built for reimbursement, not cost analysis
What actually saves you money
Be honest about which problem you are solving, because the apps split two ways. Fuel logbooks like Fuelio, Drivvo, Fuelly and Simply Auto tell you what your car costs and where the money goes. Mileage trackers like MileIQ, Everlance, TripLog and Driversnote build the log that gets you reimbursed or maximizes your tax deduction. GasBuddy does a third job, cutting the price you pay per gallon. Most drivers benefit from one of each: a price finder plus either a logbook or a mileage tracker.
The logging habit beats the app choice
Every logbook on this list is only as good as your consistency. The drivers who save real money share one habit: they log every fill-up, every time, for at least three months. That is when the charts start telling the truth about your real MPG, your cost per mile and which expenses are creeping up. Pick the app whose logging flow feels fastest to you, because the one you actually use wins.
Watch what the free tier limits
Free plans in this category usually cap one thing: drives per month, report entries, vehicles or automatic trips. MileIQ's 40 free drives, TripLog's report caps and Simply Auto's 15 free auto-trips are all fine until your driving grows past them. Check the limit against a normal month of your driving before you invest weeks of data in an app you will outgrow.
How we chose
We focused on apps with a genuinely usable free tier, not a trial that expires. For each one we checked the vendor's own site and app store listings for the free plan details, pricing and limits, then cross-checked against public reviews on the App Store, Google Play, Reddit and AlternativeTo. We separated fuel logbooks from mileage trackers because they solve different problems, and we left out apps that are discontinued, region-locked to one country or essentially gas station loyalty programs. Prices and free-tier limits change, so confirm the current terms in the app before you commit your data.
Free plans, honestly explained
"Free" means different things across this list. Fuelio, GasBuddy, Fuelly, Drivvo and Simply Auto are free in the meaningful sense: the core tracking costs nothing indefinitely, with paid tiers adding analytics or convenience. MileIQ and TripLog give you a capped free tier that suits light use. Everlance and Driversnote lead with a free trial of the full product, which is the right way to test them but not a permanent free ride. None of this is a complaint, paid tiers under $10 a month are fair for the value, but go in with clear eyes about which kind of free you are getting.
Frequently asked questions
What is the best completely free fuel tracker app?
Fuelio and Drivvo are the strongest fully free logbooks, with no expiry on the core tracking. Fuelio has the deeper feature set and the longer track record on Android and iOS, while Drivvo covers more countries with its price maps. Simply Auto's free tier is arguably the most generous of all, with unlimited fill-ups and four vehicles.
Do I need a fuel tracker or a mileage tracker?
It depends on why you are tracking. A fuel tracker like Fuelio logs fill-ups and tells you your MPG and running costs. A mileage tracker like MileIQ logs every drive automatically for tax deductions or employer reimbursement. If your car is a business expense, you probably want the mileage tracker. If you want to spend less on fuel, you want the fuel tracker.
Can these apps really save me money?
They save money two ways. GasBuddy cuts what you pay per gallon by pointing you to cheaper stations, which adds up fast for heavy drivers. Logbooks like Fuelio reveal the true cost per mile, which changes decisions about driving habits, maintenance timing and whether that old car is worth keeping. The app is free, the insight is the valuable part.
Are my fuel logs private?
Most of these apps store your data in the cloud tied to your account, and free tiers are often supported by ads or upsells. Fuelio lets you back up to your own Google Drive or Dropbox, which keeps you in control. If privacy is a priority, read the privacy policy before you log a year of driving data, and prefer apps that offer local backup or export.
Which app is best for multiple vehicles or a small fleet?
Simply Auto's free tier covers up to four vehicles, which handles most families. Drivvo and TripLog both offer fleet dashboards for businesses managing drivers and vehicles, with cost-per-vehicle reporting. For a handful of personal cars, any of the logbooks work, just check the vehicle limit on the free tier first.
Do any of these work without an internet connection?
Yes. Fuelio, Drivvo, Fuelly and Simply Auto all log fill-ups offline and sync later, which matters at rural gas stations with no signal. GasBuddy's price maps need a connection to be useful. Mileage trackers need GPS, which works without data, but the maps and syncing wait for a connection.
