As a delivery driver, I take a lot of trips. At the end of the night, each of them are shown, all of my miles accounted for, and lots of money saving up for taxes.
Edit: bug found, lost lots of miles, if your using gps other than Apple maps, it will interfere with the app. I was using waze and it missed two hours of driving. Please fix!
