Do it now is a simple todo list for Mac OSX 10.6 and newer. Creating tasks can't be any simpler - just type it into the text box, and DoItNow! should automatically parse the to-do info from your input, using natural language.
It sits silently on your menubar, and lets you set tasks, enable notifications for each tasks, and even uses OSX's text-to-speech functionality to read out tasks for you.
Great for day-to-day tasks, or even long-term alarms, DoItNow! can be used to suit the needs of anyone who needs help managing their tasks.
