Apologies for the brevity of my post.
I have used Penultimate, Goodnotes, Nebo and many others over the years and now use Noteshelf as it syncs to Evernote so that the read-only Evernote copy keeps up with changes in the Noteshelf original and allows quick and easy read-only access, filing and tagging within Evernote. It would just be easier if Evernote offered the same editing functions, with stationery and PDF import, itself. It cannot even distinguish between a finger and the Apple Pencil when sketching. Noteshelf is brilliant and any Evernote user taking handwritten notes should use it rather than any of the alternatives.
Much more frustratingly, my other major use of Apple Pencil is annotating PDF’s with script and highlights, normally using PDF Expert. Evernote is hopeless for PDF annotation on IOS, particularly with no zoom or finger/palm rejection. On MacBook it is easy to annotate in PDF Expert with changes appearing instantly in the original Evernote note. On IOS the PDF has to be copied to PDF Expert then copied back into a new note in Evernote, needing filing and tagging after every reading/annotation session - completely impractical.
I hope this explains my frustrations.
