I’m currently using Scrivenor as a general repository of notes
and files, primarily on iOS but also on Windows/Mac. My needs are
basic but it feels very solid, has an impressive feature list and
reliable sync (dropbox). It’s aimed at authors (I am not one) to
help organise reference materials and write. I just use the
former.
On the subject of Devon Think, is it a viable iOS only solution
or is the iOS app mainly a companion app?
