GasLog: Fuel & Mileage Tracker

TRACK YOUR FUEL, MILEAGE, AND GAS COSTS
GasLog helps you record fuel fill-ups, odometer readings, gas costs, and MPG in one clean fuel log. Whether you drive every day, work as a rideshare driver, manage multiple vehicles, or simply want to understand where your gas money goes, GasLog makes fuel tracking simple.
KEY FEATURES
FUEL RECORDS
Track each fill-up with date, odometer reading, fuel amount, fuel price, and total cost. Automatic MPG and fuel efficiency calculations help you understand your vehicle's performance over time.
WORK OR PERSONAL, WITH NOTES - FREE
Mark each fill-up as personal or work with one tap, and add a short note: the gas station, the trip, anything you want to remember. Handy for rideshare and delivery drivers who keep work fuel apart.
SWITCHING FROM ANOTHER APP? - FREE
Import your history from a CSV file: Fuelio, Drivvo and most other fuel apps. You choose what each column means, preview every record before saving, and nothing gets overwritten. No need to start from scratch.
FUEL HISTORY
Keep a clear history of your fill-ups by day and by month, and review past records anytime. The odometer timeline shows how your mileage grows fill-up by fill-up and week by week. GasLog works as a simple gas log, fuel tracker, mileage tracker, and gas cost tracker in one place.
UNITS & FORMATS
Set distance, fuel, efficiency, currency, number, and date formats independently. On first launch GasLog sets them up for your country, and the app speaks 41 languages.
BACKUP & RESTORE - FREE
Automatic daily backup plus manual backup and restore, all included at no cost. Save a manual backup to move your records to a new phone.
ADVANCED INSIGHTS WITH PRO
