HiTask was conceived as a friendly and easy-to-use task management system that anyone can start using right away. It is designed to satisfy both followers of David Allen’s “Getting Things Done” methodology and anyone who just needs a quick and easy tool to manage their everyday tasks.

The nice interface features a calendar, a place to write tasks and a list of the people in your team. Dragging items from one place to another produces target end dates or adds them to others' lists. Substitute assignment for project and student for solleagues, class for team and you'l get excited too. Oh, there's also a live chat facility too! Amazing. All on-line. No download.
