Gas Log

Now with expense tracking, a Stats dashboard, and time-range filters. See where every dollar goes, not just the gas.

Gas Log is the simple way to track fuel costs, fuel economy, and everything else your vehicles cost you. Log a fill-up in seconds and let the app handle the math.

Track unlimited vehicles. Add as many vehicles as you need — each with its own photo, color tag, VIN, and full history so you can tell them apart at a glance.

Automatic MPG and cost calculations. Enter your odometer reading, gallons pumped, and total cost — Gas Log instantly calculates your MPG, cost per gallon, and cost per mile. No spreadsheets, no manual math.

A real Stats dashboard. See your MPG trend over time, a full cost breakdown, and exactly where your money goes by category — filterable to the last 3 months, 6 months, this year, or all time.

Track expenses beyond fuel. Maintenance, insurance, registration, tolls, parking — log it all and see it broken down alongside your fuel costs.

Partial fill-ups supported. Didn't fill the tank all the way? Log it as a partial fill-up and Gas Log keeps your MPG calculations accurate.

Full fill-up and expense history. Every entry — date, location, gallons, cost, odometer, category — saved and easy to review.

Import and export your data. Bring in your existing fuel and expense records via CSV, or export everything anytime, right from Settings.

Your data stays on your device. No account required. No data collection. No ads. Gas Log is completely private — everything is stored locally on your device.

Made for everyday drivers. Whether you're tracking one car or managing costs across a small fleet, Gas Log keeps it simple.
