We’re excited to announce today that Simplenote for macOS 1.3 now supports Markdown. Also included is something new for a Simplenote app: the ability to see a live preview in the note editor of basic Markdown text formatting such as bold, italic, headings, etc:
You can enable the markdown editor by clicking `Markdown formatted` in the note info panel. Tap the eye icon to preview your note as it would appear when published to the web.
We’ve also included a new About Screen in this release as well as numerous bug fixes. A special thanks to all of our open source contributors who helped out!
Need to download the app? Get it from the Mac App Store here.
Happy noting,
The Simplenote Team

Simplenote Team! This is the update we’ve been waiting for – thank you, thank you! One question I have is re: the rendered formatting when we’re previewing the Markdown. How is the app determining the font used? On my machine it renders in a serif font, whereas in non-formatted, I am in a san serif. What are your thoughts? J
The app uses the system font (San Francisco) for the editor, and the preview uses the font used when published to the web which is currently ‘Noto Serif’.
Thank you soooo much for adding Markdown support! ❤
I don’t use Markdown but I love seeing activity in my favorite notes app.
Might just be kicking Evernote to the curb completely now! Thank you guys!
It sure would be nice to have a formatting toolbar instead of having to remember Markdown commands.
