Planner app with s pen, stylus support topic

I just purchased a note 4 and I'm trying to find as many apps as I can to use my s pen and replace my paper books. I use a weekly planner to keep track of my coworkers time for payroll. I'd like a planner app that has a calendar, each day is already dated, plentiful space for notes or unlimited, and I need it to be able to back up online. A little new to this note so I apologize if its something obvious. Any suggestions?
