Kapow is a punch clock program designed to easily keep track of your hours,
whether you're working on one project or many. Simply clock in and out with the
Start/Stop button. If you make a mistake in your hours, you can go back and
edit any of the entries by double-clicking on the session in question. Kapow
also allows you to easily keep track of the hours since you last billed a
client, by providing a helpful "Billed" check box--the totals will reflect your
work after the last billed session.
