A price filed last week looks exactly like one filed two hours ago.

That is how you end up driving across town to save three cents and paying more at the pump when you get there. The number was right. It just wasn't from today.

Riserva puts the age beside the price, every time. Filed two hours ago and it says so. Filed four days ago and it says that too. You pick which ones to trust before you turn the key.

What it looks like

Swipe through the app.

Map of Milan with the price printed on every filling station — The price printed on every station, coloured from cheapest to dearest.

List of stations showing each price and how old it is — Every row carries the age of its own price.

Station page working out whether the detour pays for itself — What you save on the tank, minus the fuel to get there.

Cheapest stations along a long drive, each with its detour — The cheapest ones on your way, with the exact detour.

Screen for reporting a price that differs from the one on the sign — Sign says something else? Fix it in two taps.

What you get

The age of every price

Beside each figure is the moment the operator filed it. No more numbers without a date.

Four countries, one app

Italy, Spain, France and Portugal, on the same official data. Cross a border and the app switches country on its own, and your saved stations stay in one list.

Fix what's wrong

If the sign says otherwise, report it. You can flag a closed station too. A correction goes live only once several drivers report the same figure.

Confirm it while you're there

Standing at the pump and the price is right? One tap confirms it for everyone else and puts the clock back to zero for whoever arrives next.

In the car, with CarPlay

The stations around you on the car's screen, with price, distance and brand. At the wheel Riserva shows recently filed prices only: a three week old price saves you nothing and sends you the wrong way.

Worth the detour, or not

Two cents cheaper fifteen kilometres away is not a saving. Riserva does the sum for you: what the tank costs, driving included, both ways.

Along your route

Three hundred kilometres to drive? Riserva finds the cheapest stations on the road ahead, with the detour and where each one falls in the trip.

Widget, offline, no ads

The stations you save, on your Home Screen. The data lives on the phone, so it works with no signal. No banners, ever.

Where the prices come from

From each country's own register of the figures operators are required by law to file: Osservaprezzi Carburanti in Italy, MITECO in Spain, the Ministère de l'Économie in France, DGEG in Portugal. 48,283 stations in all, refreshed every day.

Italian data under the IODL 2.0 licence, French data under the Licence Ouverte. Riserva is not a government service.
