iOS: Curious about just how much mileage your car's getting on average? Or if you have different results when you fill up at different petrol stations? Or maybe you're just curious about your carbon footprint? Jerrycan's an app that makes tracking all that stuff easy. It's easy enough to track your mileage with your car's odometer, but if you're looking to collect that data over the course of months, or add in other factors, Jerrycan's a great way to do it. Every time you fill up your tank, you enter in the volume, price, and the petrol station's location. Over time Jerrycan collects that data and displays tons of graphs to show you statistics including efficiency, distance travelled and spending. There are other apps that do the same thing, but Jerrycan's easily the best looking of the bunch.
