The Procrastinator's Timeclock is a simple utility for people who suffer from excessive procrastination or distractibility. The utility achieves its benefits by allowing you to comfortably track just how much time your little "one more thing"s are adding up to and by helping to bolster willpower by providing a gentle distraction from temptations. Its design focuses on simplicity, intuitiveness, and a preference for keeping existing users rather than attracting new ones.
TimeIT is a time tracker that works quietly almost without any interaction and still measures the time you are spending on several projects. The concept of this program is that tasks and projects are assigned to workspaces and while you are in those workspaces your projects are timed. It also has detection of idleness, editing of time records, and summary views grouped by day, week, month, and year.
The program arbtt, the automatic rule-based time tracker, allows you to investigate how you spend your time, without having to manually specify what you are doing. arbtt records which windows are open and active, and provides you with a powerful rule-based language to afterwards categorize your work.
