GoodNotes
A popular application for annotating PDF. Works with planner templates downloaded from the Internet. Supports adding stickers, covers, and various graphic elements, but they will have to be purchased separately and imported into the program base. It is almost as easy to work in it as in Digital Planner, but here you do not create your own planner, but the first search and buy a suitable template on the Internet and then open it in Goodnotes and start filling out.
One of the main benefits of the app is its advanced functions for working with text. Handwriting with Apple Pencil looks pretty well. In addition, there is a search on your handwritten text, which works well but not always correctly. GoodNotes is the go-to app for thousands of users, but the app has a couple of major drawbacks. For example, it only works on the iPad and you cannot view and edit your planner from your home computer or laptop.
