Designed to replace the logbook that you might have in your motor vehicle. Whenever a car is filled with petrol, information is entered into the Logbook App that will be stored on the Android mobile device. This allows the Logbook to calculate the average fuel consumption or fuel economy between fuel refills.
Measurements default to European (km, L, L/100 km). The United Kingdom and USA have custom localisation units. Make sure that the "Language & Keyboard" settings on your phone are correct for your location.
