Everything your vehicle needs in one app
From the pump to the garage: Rodou turns scattered notes into numbers that help you spend less.
- Real fuel economy: Average mpg (or L/100 km, km/L) with the full-tank method, the most accurate one. Partial fill-ups count automatically.
- E85 or gasoline?: The calculator shows which fuel pays off. Rodou learns from your fill-ups and finds the real limit for YOUR vehicle.
- Home screen widget: Adjust prices with + and − at the pump without opening the app.
- Reports and charts: Monthly spending, economy per tank and cost per fuel type. Export to PDF or Excel.
- Maintenance reminders: Oil, registration, insurance and tires by date, by mileage or whichever comes first, with a heads-up before it is due.
- My day: real profit: Earnings per platform, fuel cost by miles driven, profit per hour and a daily goal for rideshare and delivery drivers.
- Multiple vehicles: Cars and motorcycles in one place, with light and dark themes and your country's currency.
- Private by default: No account, no login. Back up to a file to switch phones without losing anything.
