SeeToDo app for iPhone and iPad

"SeeToDo" is a user-intuitive ToDo management tool that tells you the priority level of your tasks by their signal color. The priority of a task is automatically judged only from its due date and duration. And your tasks queue up in order of priority.
As the time limit approaches, the signal color changes into green, yellow and red, and informs you of it. Also, the color changes into black when the deadline passed.
So, it becomes clear that "which task should I do now?" or "which task should NOT I do now?"
As a result, you can focus your efforts on a few high priority tasks, then your private works or business jobs should be completed on time.

*The main feature of "SeeToDo"
To register tasks, all you have to do is entering the task name, the due date, and the duration.
After the start date, it tells you the priority by the same color as a traffic light (Green, Yellow, Red, Black).
The work item list of each task can prevent you from leaving important things behind.
The initial value of task duration can be set as the application defaults.
