En voiture Simone: every fuel price in France, on one map

Every station in France is a dot, green for cheap and red for dear, from the official prix-carburants feed. One download an hour replaces a query per visitor, and the app keeps a history of every price change.

About one price in ten had not been updated for more than a week, and one of them, from August 2025, came out as the cheapest in Paris. Prices older than seven days are left out. Next: the cheapest refill near you, counting the drive there. Source · how it was built.
