QuadrantList is a time management tool inspired by Stephen R. Covey's renowned theory, dividing tasks into four quadrants based on urgency and importance. This iPhone application aims to assist users in planning and prioritizing tasks effectively. By organizing activities into categories of urgent and important, important but not urgent, urgent but not important, and neither urgent nor important, QuadrantList simplifies time management.
