Guest-blogger and Chicago freelancer Annie Logue loves Traxtime:

Once again, I'll praise Traxtime, which I have already praised to the high heavens any time any'one will listen. It's easy to use, and it shows you just how much time you spend actually working and on what projects. It's let me raise my hourly rate, waste a little less time, and understand how profitable my different clients are. And it's shareware, so it's free – but I paid for the license, it is so good.

Has a tool or a program or a system or any of those things improved your life as a writer or editor? Drop me a line and let me know what's so great and why everyone should use it.
