What Fuelly is built to do
Fuelly: MPG & Service Tracker from Fuelly, LLC starts with the fuel-up. You enter miles, gallons and price per gallon, and the app builds your MPG data and syncs it with Fuelly.com. Its listing also covers maintenance records, customizable service reminders with presets such as oil changes and tire rotations, and charts for MPG, gas price, gas expenses and service expenses.
It supports multiple vehicles, stores details such as VIN and license plate, and emails CSV reports that open in Excel. The listing offers many unit options, including MPG (US), MPG (UK), L/100km and km/L.
As listed on October 1, 2026, the app is free with a 4.7 rating from 29,552 ratings, and the listing shows a last update of June 3, 2024. A Fuelly Premium option is mentioned, with ad removal and photo and PDF attachments, and its price is not stated.
What Carumi is built to do
Carumi is a vehicle passport for iPhone. Each car or motorcycle gets a record with photo, VIN, plate, engine, fuel type and odometer. You can scan the VIN live and scan multi-page documents, and the text is read on the device.
Maintenance schedules run by date, mileage or both, and they are completed from the current odometer. Insurance, inspection, tax, registration and warranty reminders land on the date they matter. Each service keeps its receipt, invoice and photos.
Spending is shown by category and period, with mileage history and total cost of ownership. When you sell or hand over a vehicle, you can share a Vehicle Passport PDF with privacy controls for VIN, plate, costs and documents.
Fuel economy or full history
The two apps start from different questions. Fuelly asks how efficiently the car runs, and gets the answer by recording every fill-up. Carumi asks what has been done to the car and what is due, and gets the answer from services, documents and deadlines.
Carumi counts fuel costs inside ownership costs, but its description does not mention an MPG calculation. If fuel economy is the point for you, Fuelly is the tool whose listing says it does that.
Neither choice rules out the other. A fuel log is a narrow, repeatable habit, and a vehicle record is something you update when work is done or a deadline approaches.
Where Fuelly is stronger
Fuelly's listing describes a free app with 29,552 ratings, a companion website and many unit options. If you like seeing MPG trends and want your history on the web as well as your phone, Carumi's description does not mention web sync.
The listing also mentions priority support through in-app messaging. These are all features described by Fuelly itself, and they suit someone who tracks fuel carefully.
Where Carumi is stronger
Carumi is stronger when the car needs a paper trail. It scans the VIN and documents, keeps each receipt and invoice with the service it belongs to, and sets reminders for insurance, inspection, tax, registration and warranty dates that Fuelly's listing does not mention. A maintenance schedule can run by date, mileage or whichever comes first.
It also looks past one fuel log to what the vehicle costs overall, with spending by category and period, mileage history and total cost of ownership. A JSON backup and CSV export keep the data portable, and the Vehicle Passport PDF turns the record into a document a buyer can read.
How to choose
If you check MPG after every tank, Fuelly is built for you. If you want one place that holds services, deadlines, documents and costs, and that you can hand to the next owner, Carumi is the better fit. You can run both, using Fuelly for fuel economy and Carumi for the record.
Maintenance intervals vary by vehicle, so follow your owner's manual or mechanic for what the car needs. The app records and reminds, and the manual sets the schedule.
If you only want the cheapest way to start, Fuelly is listed as free today. For Carumi's current price and availability, check its official page; compare the features that matter to you.
