I found on Lifehacker today a way to keep track of the time I spend on different tasks on the computer.
I have been working on a web site for my uncle and wanted a way to keep track of how many hours I have put in to the project. Time Tracker does the trick. It’s very simple, which is exactly what I wanted. Name the task, assign a category, and start the timer. That’s it. When you’re done, it has a small report with how much time you’ve spent on the task.
Time Tracker allows you to add comments to each chunk of time that you spend on a task, allowing you to exactly recall where all your time went. It’s AJAX allows you to drag and drop tasks and instant pop-up reports with no page-reloading.
