I am looking for a sync solution between my iPhone and Mac for working on docs. I understand Drafts can be saved in various ways to Evernote, however if I update the note in Evernote, can it be synced back to Drafts for further editing when away from my desk?
That is not possible. Drafts integration with Evernote is export only. It can create, append to and prepend to, or replace the content of notes in Evernote - but it does not have any 2-way sync with the service.
We are working on a Mac version of Drafts, but it’s not ready yet.
