After developing the PPP Petty Cash App we saw we could use the iPhone to keep track of all the trips and mileage on a production.  So, like the PPP Petty Cash App, you enter your Job information and then go to the Trips section to enter the information about each trip. You enter the date, where you went, what the purpose of the trip was for, the beginning mileage, and the ending mileage – the App figures out how many miles.  Then after syncing with your computer, you print out your mileage log and it has calculated the number of miles for each trip and what the total bill is for those miles.  It is easy to submit this log for reimbursment.
