AutoMile is an alternative to other mileage tracking apps that require recording your car's odometer reading. With AutoMile, you simply record where you went and it'll do the rest: looking up the distance traveled between stops, and keeping a running total of miles traveled. Better yet, you can do your recording when it's convenient for you: at the end of the day or the end of the year. It doesn't matter with AutoMile.
Note: Now requires OS X 10.10 or later
