Time Is Money! HD
iOS iPad Utilities
A must have app for anyone in need of tracking cost of hours worked. Two methods are available in this app for doing this.
First, record how much your time is worth per minute. Next, start the timer while your working, pause it during breaks and at the end of the day email your client what your value was for the day.
If driving is your task set the app to record miles travel and the cost you charge per mile.
