Fuel Cost: Trip & Fill

⛽ Fuel Cost — quick fuel math at the pump or on the road

Need to know how much a fill costs, what a trip burns, or your real L/100 km?
Fuel Cost is a simple offline board: pick Fill-up, Trip, or Efficiency, enter price and numbers, and see the result instantly — no account, no cards.

Works with any currency as plain numbers. Built for CIS-style liters and kilometers, but the math is the same anywhere.

📡 How it works
