TaskHarbor is a lightweight local task planner built around simple inbox, today, and completed views on Android. Users can review open tasks, check today's schedule, open completed-task history, and start creating a new task with a title, task type, and due date. READ_CALENDAR and WRITE_CALENDAR are declared so the app can support calendar-linked scheduling behavior for dated tasks. In testing, the app opened Inbox, Today, and Completed pages, and the create-task dialog showed fields for task title, Birthday/Task/Activity type, and a due date entry. The final save-to-calendar result was not independently confirmed in this smoke test.
