There is an app called Penultimate on my iPad. It allows you to take notes in a notebook. You can buy different kinds of paper to put in your notebook like music paper and game papers like tic-tac-toe. You can draw and write with a pen tool. You can also clear the page and erase. If you make a mistake you can also undo and redo. You can cut, copy, and move writing using the scissors. Penultimate also allows you to write in different colors and pen sizes. Penultimate allows you to delete, duplicate, and reorder pages. If you want to share your notebook you can email one page or all the pages.
