ManicTime is #11 in Top 10 Time Trackers

Manictime sits in the background and records your activities, so you can just forget it is there and focus on your work. When you are finished you can use collected data to accurately keep track of your time. After you have finished working, you can use MT to keep track of your hours. That means no more "punch-clock" like software, where you always forget to start or stop the clock. Just sit back and do your work. After you are finished, you can easily use collected data to accurately keep track of your time.
