Do you have a macOS or Windows version of Notes Writer?

No yet, we only offer Notes Writer for iOS (iPhone and iPad).

 

We will develop a macOS version in a near future. Meanwhile, you can edit Notes Writer RTF text notes directly on your Mac or Windows computer using TextEdit, MS Word or the more advanced Scrivener. If you use Pencil Notes or annotate PDF documents our advice is to use the Preview free app, Adobe Reader or PDF Expert to open them on your computer.
