Carbu Tracker shows fuel prices at every station in France, from the official data published by the French government, and those of Spain, Italy and Luxembourg near the borders. Find the cheapest station around you and, with Premium, follow price trends to fill up at the right time. THE CHEAPEST STATION • Nearby stations sorted by price or distance, with driving distance and time. • A page per station: every price, services (car wash, shop, air…) and opening hours. • Directions in one tap with Apple Maps, Google Maps or Waze. TIME-STAMPED PRICES • The update time of every price, and an “Old price” badge after 48 hours without an update. • Fuels that are “Out of stock” flagged on the station page. • The last 7 days’ price curve on every station page. FAVORITES AND WIDGET • Save the stations you use and find them from the map. • The Home Screen widget shows the best price near you for the fuel, distance and sort order you choose. CARBU TRACKER PREMIUM Pay less at the pump, every time. 7-day free trial on subscriptions. • Trends: curves for your favorite stations, your department’s average and the national average over 1 month, 3 months or 1 year (the last 7 days stay free). Slide your finger over the curve to read the price on any date. Plus a ranking of the stations that are regularly cheapest near you. • Good time to fill up: on each station page, see whether today’s price is a good deal against the last 30 days and nearby stations, and whether prices are rising or falling in your department. • Price alerts, even when the app is closed: threshold, % drop, out of stock, area and a weekly summary on Monday morning. • Fuel log: liters, price, mileage, real consumption, spending, savings against the department average, CSV export and receipt scanning. The log and receipt scanning stay on your iPhone. • Worth the detour?: work out whether a cheaper station makes up for the extra miles. • Trip A → B: the cheapest stations along your route, detour included. • Favorites, Price Trend (30-day curve) and Lock Screen widgets, and Siri (“Cheapest fuel near me in Carbu Tracker”).
