Can we expand our time? Better track time. (timecamp.com)

I really like the idea of doing two things at once without multitasking, as our brains don't handle multitasking that well. A very "two birds with one stone" concept.

This is like http://rescuetime.com with billing tools?

"You forgot to track time. Sounds familiar?"

That was the main reason I built http://wakatime.com, so I don't have to remember to track time.

Some people just want to sit around and relax sometimes.

How does this compare to http://www.rescuetime.com? I've been using Rescue Time for years now and it's pretty great. I can't see how timecamp improves on this, maybe I'm missing something?
