Markdown, rendered natively.

A free reader and editor for iPhone, iPad and Mac. It opens the .md files you already have and draws them with real native views, not a web page in disguise.

Your README, the way it was meant to look.

Tables, task lists, footnotes, badges and nested lists, each drawn as a native view. It launches quickly and scrolls like the rest of your device.

Diagrams, drawn offline.

Mermaid flowcharts and sequence diagrams render right in the page, with no connection needed. The source is one tap away.

Math that typesets itself.

Inline formulas sit naturally in a sentence. Display equations are set in full with KaTeX.

Code in colour, day or night.

Syntax highlighting across dozens of languages, in six themes that are tuned all the way down to the code block.
