- Cost Per Kilometer

Extra tools included:
- Round Trip switch to automatically double your distance
- Extra Fuel Buffer (5%, 10%, 20%) for hilly roads, traffic, or detours
- Distance unit toggle between kilometers and miles

FuelJourney works entirely on your device. It does not connect to the internet and does not request any device permissions. All calculations and saved values stay local to your phone.

Whether you are a daily commuter, a rideshare or delivery driver, or planning a long road trip, FuelJourney gives you a quick, clear estimate of what your journey will cost — before you leave home.

Simple inputs. Instant results. Nothing else.
