GoodNotes is an app that enhances your digital planner experience. Do you need to download GoodNotes to use our digital planner? No, you can download and use any notetaking app. However, using GoodNotes simulates the experience of using a paper planner by allowing you to write on and add stickers to your virtual planning pages, as well as turn the pages the same way you would with a paper planner.
