I wrote up my GoodNotes journal pages a few months ago. Since then, I have found myself increasingly using a paper journal for much of this data, but I know a bunch of readers wanted to modify my forms. Links are below in OmniGraffle, PSD, and PNG format. (I built all of these using OmniGraffle.)
These differ from the versions I made for myself in that I used a custom flavor of Futura that I purchased years ago. I changed the font to a system font for these downloads and changed some of the titles specific to me, such as working on a Field Guide every day, to something more generic. Enjoy, and let me know if you make something amazing with them.
Once you complete customizing your form, export to PDF, and you can then import and edit them in GoodNotes. You can leave them right in GoodNotes or, if you are a fancy Day One user like me, export the completed page as an image to Day One. Sort of related, Tom Solid made his own forms that are far superior to mine if you want more detail.
