Marked

Markdown, beautifully native.

Marked opens Markdown files through the system document browser, lets you edit the plain source, and renders a polished live preview on device, complete with math, diagrams, and syntax highlighting.

Your files stay plain and portable. Marked never locks your writing into a proprietary format.
