This app helps you organize cluttered tasks—like shopping lists or work assignments—by category. A countdown to each due date is displayed, making it easy to manage expiration dates and deadlines. You can reorder both categories and tasks via drag and drop. [Categories] Simply set an icon and title to create a task category. You can also hide categories you don’t want shown on the main screen, such as those you use less frequently. Note: Category titles are optional. [Tasks] Task priority can be set in three color-coded levels: red, orange, and green. Completed tasks are automatically moved to the bottom of the incomplete list. [Due Dates] Set a due date to display a countdown showing the days remaining. Notifications can be set in five timing options: Today only, 1 day before, 3 days before, 7 days before, or 14 days before. [Recurring Tasks] Choose from daily, weekly, monthly, or yearly recurrence and set it with a simple tap on the day or date. Once a recurring task is checked off, it will automatically reset the next day. All data is stored only on your device and never shared externally. Choose from 8 different theme colors to customize your app experience.
