IS THE DETOUR WORTH IT?
A low price per liter alone doesn't necessarily mean you'll save money. Tank Smart's "Best Choice" feature also considers estimated fuel costs for a round trip based on distance, fuel consumption, and fuel quantity. This allows you to compare the cheapest gas stations based on the anticipated total cost of your fill-up.
The detour calculator shows the estimated savings in euros and the minimum fuel quantity required to make the extra trip worthwhile. Fuel Timing provides a time estimate for your next stop.
WIDGETS, NAVIGATION, AND OFFLINE VIEW
Keep track of the lowest reported gasoline or diesel prices with a widget on your home screen. Start your route to the gas station in your map app. Without an internet connection, the last loaded prices with timestamps remain visible; these may have changed since the last update.
