Mileage and Fuel Logs
Log odometer entries, fill-ups, charging sessions, and fuel costs in one place so every vehicle record stays easy to review.
SimpleFuel
A mileage tracker app for iPhone that helps drivers log fuel, charging, MPG, MPGe, and maintenance for gas, electric, and hybrid vehicles.
MPG and EV Efficiency Tracking
Track MPG, MPGe, and energy usage for gas, electric, hybrid, and plug-in hybrid vehicles with calculations built for each case.
Maintenance Tracking & Reminders
Create maintenance reminders and log service history so oil changes, tire rotations, and repair records stay organized.
Why drivers use SimpleFuel
One iPhone app for tracking mileage, fuel cost, and vehicle maintenance.
SimpleFuel is designed for drivers who want a cleaner way to keep a fuel log, track efficiency trends, and understand cost per mile without falling back to spreadsheets.
For gas vehicles
Track fill-ups, MPG, fuel cost, and long-term efficiency with a mileage log with a clean, modern iOS design.
For EVs and hybrids
Record charging sessions, energy use, and MPGe so electric and hybrid driving data stays comparable over time.
For long-term ownership
Keep service records and maintenance reminders tied to the same vehicle history as your fuel and mileage entries.
Frequently asked questions
Does it work for electric and hybrid vehicles?
Yes. SimpleFuel is designed for gas, electric, and hybrid vehicles.
How does SimpleFuel calculate efficiency?
SimpleFuel uses MPG and MPGe as the units of efficiency. MPGe (Miles Per Gallon equivalent) is an EPA-standardized measurement indicating how far an electric or alternative fuel vehicle can travel on an amount of energy equal to one gallon of gasoline. One gallon of gas is estimated to have the energy equivalent of 33.7 kWh of electricity.
Gas vehicles: MPG = miles driven divided by the amount of gas used at fill-up.
Electric vehicles: MPGe = miles driven divided by energy used, where energy is calculated as kilowatt-hours used divided by 33.7.
Non plug-in hybrids: Same as gas vehicles because electric power is derived from the gas engine.
Plug-in hybrids: For plug-in hybrids, SimpleFuel uses two efficiency views. At a full gas fill-up, it calculates a combined MPGe using miles driven since the previous full fill-up divided by total energy used in that cycle, where total energy is gas used plus charged electricity converted using 33.7 kWh = 1 gallon of gasoline. Charge entries are tracked separately as electric-only efficiency between full charges. As a result, the most representative overall hybrid efficiency is the MPGe shown on gas fill-ups.
Can I track more than one vehicle?
SimpleFuel+ allows you to track up to three active vehicles and review their fuel efficiency and maintenance history individually.
What does SimpleFuel+ include?
At launch, SimpleFuel+ includes support for tracking up to three active vehicles and recording services and maintenance. More premium features will be added over time.
What platforms does SimpleFuel work on?
SimpleFuel currently runs exclusively on iPhones and is compatible with iOS 18 and newer.
Does SimpleFuel support CarPlay?
Not yet...
Can I import my data from another app?
SimpleFuel currently supports importing data from a previous SimpleFuel export or from a Fuelly export. Some information, such as location data and notes, may not be cleanly imported. It is suggested to back up all data before importing. If you encounter issues upon import, please contact me via our support email (support@simplefuel.app).
Is my data stored locally?
Yes. Your records stay on your device so your history is available when you need it. Please review the SimpleFuel Privacy Policy for more information.
Is my data backed up to the cloud?
SimpleFuel does not currently support Cloud syncing. You may include SimpleFuel data in your iCloud Backup to be used for migration to a new device or restoring data. This does not sync your data across devices.
