Kapow is a punch clock program designed to track spent time, 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” checkbox — the totals will reflect your work after the last billed session.
Kapow is free and open source software built with Qt5.
