Kapow – punch clock program designed to track time

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.

Features include:

  • Automatic backups of time data.
  • Inline editing.
  • Start, stop, or cancel sessions from the sidebar.
  • Multiple timers.
  • Printable reports.
  • Exporting reports in HTML / iCalendar / CSV formats.
  • Filtering sessions.
  • Automatic high DPI support.
  • Internationalization support including support for Arabic, Bulgarian, Czech, Danish, French, German, Greek, Italian, Lithuanian, Norwegian, Polish, Portuguese (Brazil), Romanian, Russian, Spanish, Swedish, Turkish, and Ukrainian.
  • Cross-platform support – runs under Linux, macOS, and Windows.
