Best Phone App to track mileage?

I use Carango (android app). Beside being able to export in Excel format, you can keep track of fill ups, oil changes, service cost tracking, tracking of expenses (accident, car washes, parking, financing, etc), Insurance tracking. It then can report how much per km or mile you are paying to drive your vehicle. The pro version allows tracking of all expenses related to the car and can report what your true cost to operate per km or miles. It the only app I have used so far.

Old car $0.55/km
Prius V $0.231/km so far (financing and insurance included).

Old car one month 450L of fuel
Prius V similar distance 178L of fuel (3379 km traveled)
