To add to the other alternatives: remember that there's Excel, i.e. spreadsheet software. It's my current method for organizing and monitoring my solo work. Some of the useful features:<p>- Handling dates, intervals, boolean values.<p>- Formatting, and conditional formatting. Colors, fonts etc. without the non-utilitarian, "sleek" burden of modern web design.<p>- Collecting reporting information with SUM(), IF(), COUNTIFS() and friends.<p>The main benefit is that it's very flexible with only very minimal programming. I can reserve my coding time and stamina for the tasks that absolutely need it.
