Remarkable instructions for use:
Apple accounts are interoperable, and all notes are synchronized under one account, but if you want to use them on a Mac, you need to pay, while iPhone and iPad only need to pay once.
You can import PPT and PDF files into your notes, and you can watch courseware sketch courseware, which is one of the reasons why college students use it the most, making your schoolbag lighter. You can also create a separate notebook to write notes without buying a notebook, thus reducing the pressure on your schoolbag and wallet.
