All in One Calender, Tasks and Notes App

An application with all in one features that includes task/reminder, notes and calender. This application should be easy to navigate and the user should be able to create and link all three categorise together. Task/Reminder Should be able to select date Should be able to select time Add labels Priorities Description Notes: Attach files Link with tasks Labels Calender: See tasks on the calender easily Easy to use Agenda, Day and Month switch over This are some of the features I would like to include in the application. I would also love to see a minimalistic design which is stylist and easy to interact with for the user. The other important feature I would like to see is the clear notification on both notification bar and on the screen itself.
