If you're reading this, you probably missed the free upgrade period from GoodNotes 4 to GoodNotes 5 which was from January 15th, 2019 to January 15th, 2020.
We want to excuse ourselves for that and unfortunately, the free upgrade is no longer available.
We still hope that you will consider getting GoodNotes 5 at the regular price. Since the initial launch on January 15th, 2019, our team has worked hard and delivered a significant number of updates with improvements, new features, previously missing features, and bug fixes. We will continue to release exciting new updates for free for existing users of GoodNotes 5.
