LiveGasCost
Live · in real time

See what your drive costs — live.

Start driving and watch the real dollars leaving your tank climb in real time — mile by mile, as you drive. Your car's real EPA MPG against real regional fuel prices, so the number is the actual number.

From 99¢, once — never a subscription. No account, nothing on a server.

Android: grab the beta now — your phone will ask you to allow installs from your browser (normal for a beta outside the Play store). iPhone: the beta is invite-only on TestFlight — leave your email below and we'll invite you as it opens up.

One email when it reaches the stores — and your TestFlight invite if you're on iPhone. Nothing else.

The LiveGasCost Track screen recording a drive: a live trip cost in large green figures, with miles, elapsed time, idle time and dollars per mile beneath it, and an End trip button.

Fuel prices are EIA US regular average$4.08/gal for the week of Aug 24, 2026 — and the five regional figures above are the EIA's own weekly series for the same week. The worked example further down is priced at EIA Midwest (PADD 2) regular average, $3.93/gal, because it is a Madison drive. All of it is refreshed weekly from the EIA's own series. Distances come from real roads on our own routing server, not straight lines. MPG comes from the EPA's published ratings for the exact car you drive.

Your cost, right on the dash

Mount it, start driving, and watch every mile add up in real time — the whole trip, right where you can see it.

How it works

Three steps, and you only do the first one.

  1. Step 1: Install it

    Download the app and pick your car from the EPA database. That is the setup — no account, no sign-up, no email required.

  2. Step 2: Drive

    Turn on automatic detection and the app notices your drives on its own. Or hit Start trip when you want to. Either way, nothing leaves the phone.

  3. Step 3: See what it cost

    Watch the dollars climb live as you drive, and find every trip waiting in your history afterwards — priced from real roads, your car's real MPG and this week's real fuel price.

For drivers

Everything your fuel budget needs, and nothing that needs an account.

Real-time tracking

Start a trip and watch the cost tick up live — GPS distance, your vehicle's real MPG, and local fuel prices, priced per mile as you drive.

Multi-vehicle garage

Save every vehicle you drive — commuter, truck, diesel — and switch with one tap. Each keeps its own MPG and fuel type.

Manual price override

Filled up at a price the averages don't know about? Set your exact price per gallon and every calculation uses it until you clear it.

Install it. Drive. See the cost.

Six screens from the real app — one trip, start to finish: priced live, mapped, logged, and planned before you leave.

Live cost tracking

Watch the dollar figure climb as you drive. Shot on an earlier build, before a vehicle was added — the app priced it at its then-default 33 MPG and $3.20/gal.

A finished morning commute: its route drawn along real streets on a map between two Madison addresses, and the full stats — 10.1 miles, 27 minutes, 31 MPG, 0.33 gallons used.

Mapped trip detail

Snapped route, addresses, and full stats. A real drive from Aug 15, 2026, priced at that week's gas — $3.81/gal Midwest regular.

The Drives list: each trip a card with its cost, distance, vehicle and a map of the route it took.

Every trip, logged

Your drive history with cost and MPG. Real drives from Aug 2026, each priced at the gas that week.

The Plan tab with the search box open and 'Sun Prairie Wisconsin' typed into it. Six results are listed with a name and a one-line address each — Sun Prairie in Dane County, Sun Prairie East High School at 888 Grove Street, Town of Sun Prairie, Prairie Lakes, Prairie Enterprises and Prairie Homes — above stops already added as A and B chips.

Type a place, not a coordinate

Search by name. The addresses come from our own server.

The Plan tab: a map filling the screen with a route drawn along real roads from Waunakee round Lake Mendota through Middleton to Verona and on to Sun Prairie, the stops listed as A, B and C chips, a banner offering 'Cheapest order saves $0.81 — Reorder', and a panel reading 58 minutes, 48.099999999999994 miles, $6.16 fuel.

Know the cost before you go

Real roads, real distance. This shot was taken before a vehicle was added, so the app priced it at its placeholder 25 MPG and $3.20/gal — add your vehicle and both become yours.

The same planned trip with the cost view switched to Per stop: A to B is 19.9 miles and $2.55, B to C is 28.2 miles and $3.61, under a $6.16 total.

Total, or stop by stop

$2.55 the first leg, $3.61 the second — and they add up. Same 25 MPG and $3.20/gal the screen above was shot with.

Fuel used4.6 gal
Gas price$3.93/gal

148 mi ÷ 32 MPG = 4.625 gal × $3.934 = $18.19 — the same math the app runs live, every mile.

Fuel price: EIA Midwest (PADD 2) regular average, week of Aug 24, 2026 — a Madison drive, priced at its own region rather than at the national average above.

Questions, answered

How accurate is the MPG?

Vehicle MPG comes from the official EPA fuel-economy database — 24,685 vehicles back to 1984. Heavy-duty trucks the EPA doesn't rate (192 of them, mostly 2500/3500 pickups) use clearly-labeled real-world estimates, and you can always enter your own number if you know your true average.

Can I track multiple vehicles?

Yes. Save each vehicle to your garage with its own year, make, model, fuel type, and MPG, then switch between them with one tap on the Track screen. Diesel vehicles automatically use diesel prices.

Are the gas prices real-time?

Prices are official EIA regional averages, refreshed as you drive. You can override with your exact pump price anytime.

Does it work offline?

Trip tracking does — GPS needs no connection, and a manual price override keeps cost math running without signal. Live price lookups resume when you're back online; nothing is lost in between.

Where does my data go?

Nowhere. Your drives, routes, and history live on your phone — there's no account to make, no server holding them, and nothing sold to anyone.

What vehicles does it support?

Any car, truck, or diesel in the EPA database (24,685 vehicles back to 1984), plus manual entry if yours isn't listed or you want to use your own MPG.
