iA Writer is one of the most established and widely-acclaimed Markdown editors. Considered to be a “gold standard” Markdown editor, iA Writer is available for devices running macOS, Windows, iOS, and Android operating systems. The application allows you to export Markdown files to HTML, PDF, and Microsoft Word file format using custom templates.

One of the hallmarks of the application is focus mode. When enabled, that feature keeps the sentence you’re currently working on horizontally centered, as shown in the screenshot below. It feels a little like using a typewriter.

There are a couple of quirks you should be aware of. iA Writer doesn’t save new files with the Markdown extension (.md) by default. If you plan to exclusively create Markdown files using iA Writer, you should change the default extension to .md in Preferences > Files.

The Preview button is the little triangle button in the top-right corner of the window. You can click that to preview the output, and then click it again to return to the source.
