This program has been written to get to know Eclipse 4 RCP development, EMF and other cool stuff.
Nevertheless this program is very helpful and I use it on a daily basis.
Weekly I have to tell the company I work for, for which activities I spent how much time. The WorkTracker helps enormously to record the spent time for several activities. Every time I start working on a new activity I document it within this tool. Many features make this very easy. When the time comes that I have to explain how much time I spent for which activity, this can be easily seen in the WorkTracker, e.g the program calculates the sum of durations for each activity.
