Which productivity tracker is that? I'm using Harvest to manage my time per client / project and it handles invoicing them as well. As fun as it is to invoice myself for wasted hungover time at the end of the month, I feel like yours and your pretty graphs would be infinitely more useful.
It's RescueTime. You can try it out for free (like I do) but there's also a pretty nifty premium package. I do have to note though that it hasn't been perfect so far: if you switch apps a lot, it doesn't register as accurate as it should. For example, I am now braindead because I've spent all the goddamn day working on my bigass paper. I've not really taken a break, but none of the bars add up to a full hour. Some get close (58 minutes) though. But hey, I'm over a dozen used academic sources and these counters were at zero this morning: I know you didn't really ask for this info but I gotta tell someone of my most productive day ever, y'know. Edit PS: God I love Garamond. Best font ever.
