Not good if you cross the border

This app works perfectly if you stay in the US. If you drive to Canada and fill up, you have to manually convert litres to gallons and km to miles before entering the data into the app. If you switch units in the app, it simply changes to unit but doesnt convert the data already there to the new unit, which throws all the calculations off. For example, enter units in miles and gallons but display mileage as L/100km and the calculation is way off. So its a great app as long as you never change units and do your own calculations when required. Not recommended if you cross the border into Canada
