How Fillz works

The cheapest fill-up isn't always the nearest. Fillz finds the one that actually pays off.

Compare every fuel station and charging point around you, see which one saves you the most once the detour is counted, and check live EV availability, with official data where it exists and the community where it doesn't. In your language, in every country we cover.

Free No sign-up Your location never leaves your device

The number on the sign is only half the story

Fuel prices swing by 15 to 20 cents a litre between stations on the same street. A charger three streets away might be occupied, broken, or twice the price. And the “cheapest” pump can quietly cost you more once you burn fuel driving to it.

Most maps stop at “here's what's near you”. Fillz answers the question you actually have: where should I go right now?

Three steps, a few seconds

1

See everything around you

Fillz locates you and pulls every station in your radius, fuel or electric, ranked the way you choose: cheapest, nearest, or best value.

2

Compare like for like

Same fuel grade, same connector, same units and currency. Every price comes from the most trustworthy source available for your country.

3

Go to the one that pays off

One tap opens turn-by-turn navigation. The station Fillz highlights is the one that leaves the most in your pocket, detour included, and any brand discounts you set in Settings folded into the total.

Where our prices come from

Trust is the whole product. Here's exactly how we build the price you see, source by source.

How the coverage is built

Every price on Fillz comes from one of three places, and each one is named on the card that shows it.

Fillz. Station counts from our own provider configuration; the price gap measured live in ten European cities on 2026-09-08.

Official feeds

When a country publishes station-level prices, we use that feed directly: DGEG in Portugal, ANP in Brazil, Osservaprezzi in Italy, and dozens more national sources. Each updates on its own schedule.

Community-built

Where no official source exists, we assemble the map the way the best local apps do: OpenStreetMap for the stations, plus driver reports and price photos you can confirm or flag. Transparent by design.

Live EV networks

For charging we connect to official networks. In Portugal, that means real-time points and free-connector counts straight from MOBI.E via the national access point. You see how many connectors are free before you drive over.

Every station carries its source. If a price looks off, you can report it in two taps, and the community keeps everyone honest.
The Fillz difference

“Cheapest” and “cheapest for you” aren't the same

A station 4 km away at 5 cents less can cost you more than the one around the corner, once you count the fuel you burn getting there. Fillz runs that math on every result and flags the one that genuinely pays off. We call it worth the detour.

Built to feel local, everywhere

Fillz speaks 24 languages and adapts to each country: the right fuel grades, the right connectors, the local currency and units, the national data source. A driver in Lisbon, Warsaw, Santiago or Sydney gets an app that feels made for them, not translated at them.

Questions, answered

Is Fillz free?
Yes, completely. You can browse prices, compare stations and navigate without paying anything or creating an account. An optional one-off purchase removes ads for those who want it.
How current are the prices?
Each source updates on its own cadence. Official feeds are often daily or intraday, community prices appear the moment a driver reports them, and EV availability is near real time wherever the network provides it. Every station shows when its data was last updated.
Do you track my location?
No. Your position is used on your device to find nearby stations and isn't stored by us. Analytics only run after you accept them, and you can decline without losing any feature.
Which countries are covered?
Official station-level prices across more than 20 countries, community coverage in many more, and EV charging worldwide. The list keeps growing, and the app automatically adapts to the country you're in.
Is EV availability really live?
Where the official network publishes it, like MOBI.E in Portugal, the answer is yes. You see how many connectors are free at each site, refreshed continuously, so you don't drive to a full or out-of-service charger.
