An app that culcuates how much time a person wastes for the ipod touch/iphone

This would be a ipod touch and iphone app, How it works the user would press start when he or she was not being productive and the app timer would start when the person started doing something important they would stop the timer and it would show how much time was wasted it would show how much time was wasted in a 24 hour period 48 hour period and so on and the person would be able to look back and calculate the total time wasted in a month and a year if they wanted to. This app would also have a task reminder you would put in things you had to do for a certain day and what time and the task would pop up at that time reminding you.
