Startup Idea : always looking out for u

we often want someone to remind us of our schedule and tasks piling up with a deadline. someone to tell that if u don't wake up now, you will be late. a friend to listen when no is around. keep our secrets safe. i want an app which once fed with the day's or week's schedule, will look out for us constantly so that our work is on time. we can take notes in it and make personal entries too. All in one and one for all app.
