Everything a driver needs.
Plus the live number built on your own MPG.
Live gas cost while you drive
Every other driving app is a rear-view mirror — a report after the money's gone. LiveGasCost shows your estimated gas cost climbing in real time, mile by mile, using your car's MPG and your region's weekly average gas price. It's the windshield, not the mirror.

The full toolkit
Everything you need to see what driving actually costs you — done simply, and privately.
Automatic drive detectionAndroid and iPhone
Turn on automatic tracking and just drive — trips record themselves in the background, even in your pocket, on Android and iPhone. You can still start and end a drive yourself.
Real routes, no big-tech tracking
Maps from OpenStreetMap, location handled on your device — accurate tracking without big-tech tracking you.
Your exact pump price
Regional averages by default. Know what you actually paid? Type it in and every cost recalculates against your real number.
Keeps working without signal
GPS needs no connection and your car's MPG is bundled inside the app, so a drive through a dead zone still records and still prices itself.
Estimated fuel cost
Your car's MPG × your region's weekly average gas price = the estimated gas cost of each drive.
Export your drives
A plain CSV of every drive and what it cost — yours to keep, open anywhere.
Your car's own MPG
Type in the MPG your car gets and change it any time. Every drive's cost is worked out from it.
Spend stats
What you spent on gas today, this week, this month and all time — added up automatically from your drives.
Private by default
Your drives are saved on your phone, and the app does not send them to us. We never sell your location. Delete means delete.
Know what every drive costs.
The live gauge, your drives and their maps, and your totals — 99¢ once, when available, and it never renews.
