I designed a TO-Do list that is going to help you boost your productivity level. i named it "To-Do on Steroids". what is special about To-Do on Steroids is that here you can divide your tasks based on:
7 Days Task
Family and Friends
you can add the relation of tasks you are going to add and add a recurring interval if the task is repetitive.
you can add the Due Date of Task,
you can set the priority of the task.
there is a view to see the tasks of different intervals as well.
