I've made a pomodoro timer app that also gives me a summary over which apps and websites I have used during the last 25 minutes when a pomodoro is over. (http://www.beatpoints.com/cherrytomato)

This is good feedback about whether I actually managed to focus on the task that I planned.

However, I find that pomodoros are not the right granularity - to really be productive, I need to focus on one task for an entire day (related: pg's Maker's Schedule, Manager's Schedule: http://www.paulgraham.com/makersschedule.html). This is still really hard for me to do.

Would be nice to have a cross platform version of this :)

I agree :-) For now, it's just a hobby project but if it becomes popular then I might put the energy and time into porting it.

Open sourcing it may be an option... then someone else would do the dirty work for you.
