Buggy with PDFs.
GoodNotes handles handwriting very well, maybe the best app in the class for that purpose, but it is too buggy in handling big PDF files.
It is a pity that:
Opening a simple PDF book with outlines crashes the app. Trying to view the outlines again crashes the app.
Syncing is not good. Syncing files across multiple platforms is impossible.
And there is no way to write RTL notes .
