Notes applications are a dime a dozen these days, and Mac users have a lot to choose from. Apple gives us two notes apps in MacOS High Sierra, and one of them syncs notes with other Notes apps on iPhone and iPad. What's not to like?
If notes apps are everywhere and priced as low as dirt, then why so many? The key to product marketing is differentiation. Not all notes, text editors, mini-text processors, and author or encoding tools have been created alike. FSNotes is different.
Notes apps have existed as long as computers have existed. People take notes in many forms. Notational Velocity was a precursor to many such notes apps today and was quite popular on Mac OS X back in the day.
Notational Velocity is a computer program for Mac OS X used for listing. It allows users to create notes that only use a keyboard and search for them using incremental searches. Other features include database encryption, basic text formatting, tags and spell checking.
FSNotes carries the notation rate and the nvALT tradition. It respects open formats, including plain text, RTF and Markdown. Files can be viewed, edited and copied to the most popular editors.
FSNotes is not a mini-word processor. There is nothing like TextEdit or Notes on Mac. Instead, this is a tool for Mac geeks or wannabe geeks who love the keyboard for notes, that is, the extensive use of the hot keys, but everything works in an app instead of Terminal.

- ] Markdown Images Editor Preview
- ] Drag and Drop Pictures  FSNotes allows you to manage files from the left sidebar. It has themes and highlight codes and can be the most user-friendly Markdown app I've seen in a while.
Store storage settings can be easily changed so you can use Dropbox or iCloud Drive, which makes the files available to other Mac text editors. And yes, FSNotes is available free of charge on GitHub as an open source project, but also user-friendly on the Mac App Store for a few bucks to help development development. Think of it as cheap but geeky power notes app for Mac users.
