Because it can be a bit difficult to keep track of the amount of hours that you put in when managing multiple projects, if you’re looking for a computer oriented ‘punch clock’ program, then ‘Kapow’ is a free tool that’s worth trying. It’s open source and a cross-platform software that runs in MS Windows, Mac OS X and GNU/Linux platforms.
‘Kapow’ is also a pretty user friendly tool too. You start the program, add your projects and hit the ‘Start’ button when working on one. When done working on that, click on the ‘Stop’ button and it’ll save that session (in hours) under that project’s name. If you have more than one session per project, then it automatically calculates the total hours based on the sessions.
You can generate reports and Print them or save (export) them into HTML, iCalendor or Outlook CSV formats (you can also include fields such as ‘Company’, ‘Name’, ‘Address’, ‘Fax’, ‘Phone’ etc too). It also lets you calculate your ‘cost’ by based on the Hourly and Tax rates (including manually adding currency symbols) as well.
Installing it …
If you use Ubuntu 12.10 Quantal Quetzal, 12.04 Precise Pangolin, 11.10, 11.04 and 10.10 by using the developer’s official PPA (up-to-date packages).
For that, open your Terminal and enter the below command.
sudo apt-add-repository ppa:gottcode/gcppa
sudo apt-get update
sudo apt-get install kapow
That should do it.
For other OS users, please visit this ‘Kapow’ project page for downloading it manually. Good luck.
