Battle your procrastination with hard facts. And pie charts!
Soglog keeps track of your active window, telling you how much time you've spent on your work, study or research, and how much was wasted surfing the internet or playing games. You probably know what I'm talking about.
The name is derived from the Dutch acronym SOG, for Studie-ontwijkend gedrag, which translates to "Study avoidant behavior". It can also be used as a verb. "I sogged so hard today!". In fact it's pretty close to the English word "procrastination". So, this programs helps to log your sog. Obvious limitation: it only detects which window is open, it doesn't know whether you're actually working, or dozing off, staring into the distance, annoying the people around you, etc.
Note: This is strictly intended as a personal productivity tool. It is not okay to use this to record someone else's activities without their consent! Also, no data is sent or stored anywhere.
