Work Time Recorder
Work Time Recorder is a simple time tracking tool that allows you to keep track of the time spent on different tasks throughout the day. You can create multiple tasks and switch between them, automatically keeping track of the time spent on each. Even though the main interface will reset the task time every time you stop (which may confuse you), the report option will generate a summary of the combined time spent on each task over a selected period of time. Work Time Recorder is small and simple, it does not offer any sophisticated features, however it is straightforward to use and gets the job done.
