simple reminder servic on home screen

[AC Question]

On the note 4 for example, pull out your pen, write dont forget appointment 0900 weds, press the three dots, click set on home screen, everytime you use the phone the message is there without having to do anything, I know stickies, but is there anything easier than them, I want a new phone and it was going to be note 7, but I really need a good reminder service.
