MarkdownPad
MarkdownPad is a full-featured Markdown editor for Windows. Instantly see what your Markdown documents look like in HTML as you create them. While you type, LivePreview will automatically scroll to the current location you're editing. Markdown formatting can be applied (and removed) with handy keyboard shortcuts and toolbar buttons. You don't need to know anything about Markdown to use MarkdownPad! Color schemes, fonts, sizes and layouts are all customizable so you can turn MarkdownPad into your perfect editor. Change the look of your HTML documents by using your own CSS stylesheets. MarkdownPad supports multiple stylesheets and has a built-in CSS editor. The default CSS is beautiful and minimal, and will make your HTML documents look great. Quickly create ready-to-use HTML documents, or simply copy a portion of your document as HTML. MarkdownPad Pro supports multiple Markdown processing engines, including Markdown Extra (with Table support), and GitHub Flavored Markdown.

Byword includes complete Markdown support. Preview your documents in app, export to HTML, PDF, rich text, or publish directly to Medium, WordPress, Blogger, Tumblr and Evernote. The lack of support for rich text is due to technical limitations and limited development resources. We are evaluating the cost/benefit of investing in rich text support of iOS. Meanwhile, we strongly recommend opting for plain text and markdown format for your documents. Macworld has a great article explaining why opting for plain text today is a good idea.
