Use Sofa to keep track of deadlines. Add a project or task and set the date when you should finish it. Sofa will then display what you need to work on as a simple list. You can also use it as a daily to-do list. Either way, each day, the previous day’s list will disappear.
Sofa’s functionality is basic by design—it’s meant to be used however it works for you. It started as an excuse to learn Rails, but was also meant to solve a real personal problem—that of organizing one's own time, especially for those without typical jobs.
