Markitown: Markdown Editor

Markitown is a Markdown editor and viewer for iPhone and iPad. Open any .md file from Files or iCloud Drive and see it the way it's meant to look: GFM tables, task lists, highlighted code, LaTeX and Mermaid, beautifully rendered. Made for the way you work with AI, too: open skills, subagents, AGENTS.md or your favorite AI agent's constitution file and read them formatted, YAML front matter and all. Reading is free, with no limits. When you're ready to write, one purchase unlocks the editor on every version: iPhone, iPad, Mac and Apple Vision Pro. No subscription, no account.
