Gas Log

Gas Log is the simple way to track fuel costs, fuel economy, and everything else your vehicles cost you. Gas, diesel, or electric, miles or kilometers: log a fill-up or charge 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 (pick a preset or any custom color by hex code), VIN, and full history so you can tell them apart at a glance. **Automatic fuel economy and cost calculations.** Enter your odometer reading, how much you filled up, and the total cost — Gas Log instantly calculates your fuel economy, cost per gallon (or liter, or kWh), and cost per mile. No spreadsheets, no manual math. **Your units, per vehicle.** Each vehicle picks its own units: miles or kilometers, and gallons, liters, or kWh. See MPG, km/L, L/100km, mi/kWh, or kWh/100km, whichever you actually use. Set your default once in Settings. **Built for EVs too.** Log home and public charging in kWh, track cost per kWh, and follow your efficiency over time. The gas car and the EV can live in the same garage. **A real Stats dashboard.** See your fuel economy trend over time, a full cost breakdown, and exactly where your money goes by category. **Any date range, on every tab.** Pick the last 3, 6, or 12 months, year to date, all time, or any calendar year. Stats, fill-ups, and expenses all follow the same range, so years of history never mean years of scrolling. **Track expenses beyond fuel.** Maintenance, insurance, registration, tolls, parking — log it all, grouped by month with a total for each, and see it broken down alongside your fuel costs. **Fuel economy you can trust.** Partial fill-up? Gas Log counts that fuel toward your next full tank, the same full-to-full method serious trackers use. Forgot to log one? Mark the next fill-up as "missed previous" and it stays out of your averages instead of skewing them. **Switching from another app? Bring your history.** Import a CSV from your old fuel tracker. Gas Log matches the columns, reads the dates, and flags rows that look like typos (a misplaced odometer reading, a $2,000 tank of gas) so you can review them before anything is saved. **Export anytime.** Export everything, or just one vehicle, as a CSV right from Settings. **Easy to read.** Gas Log follows your phone's text size, so larger text just works. **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. --- Download Gas Log and start tracking every mile and every dollar. ---
