Klok
Keeping track of time is always a bitch on a given project. Of course you could always just keep a notebook handy (which I have done a lot) and jot down hours, but its so much better to have a program do it for you. Klok is just that. Its a simple, clean, straight up app available here. It’s been pretty cool for me so far in the week or two that I have been using it and I recommend it for a FREE time tracking tool.
