Digital Notebook is a notebook app that lets you use a stylus to write and draw on top of digital pages. It can also save your notes in PDF and other formats, and has a calendar to help you keep track of important dates.

It is a very simple and easy-to-use app. You just need to write down what you want to remember, what you think might be useful, and what you want to do. Digital Notebook will take care of the rest. It can also save your notes in separate stories so you can keep them organized and easily find them again.
