Planner is a flexible organizer application for students based on a simple checklist. It is designed to enable users to plan and organize their work without any distractions. Planner focuses on what's really important - deadlines. A straightforward checklist - a foundation of Planner - allows students to have a clear vision of tasks at hand and their due dates. Customization tools allow for unique design for every possible task description students can encounter. An array of possible displays - from a basic checklist to a calendar - will give students a greater perception of time and workload.
