You get a tasklist and voila! the time shows up on your toolbar, the seconds passing before your very eyes. It will also provide reports for you, which will give you a good idea of how you've been using your time if you've kept up your SlimTimer entries like a good girl.

I admit to being rather Old School, and I still have a passion for my FranklinCovey binder ....Maybe it's that lawyer in me, and all that early DayTimer training.
