Kapow is a punch clock program designed to keep track of your hours in one, or multiple projects.

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” checkbox—the totals will reflect your work after the last billed session.
