MD Flow is a native app for Mac, iPhone, and iPad that lets you browse, preview, and search folders full of Markdown files — instantly. No setup, no account, no editor to wrestle with.

MD Flow is a reader, not another editor. Point it at a folder and start reading.
Click a file and it renders instantly — Mermaid diagrams, KaTeX math, Obsidian-style callouts, and YAML frontmatter included.
Point MD Flow at any folder — AI exports, notes, an Obsidian vault — and arrow through files with live previews.
Full-text search across your connected folders. Find files by what's in them, not by what you named them.
Turn any document into a clean PDF — math, diagrams, callouts and tables all survive the page.
Give a Markdown file a “to:” line and it becomes an email — subject and recipients on top, one tap to open it prefilled in Mail, Gmail, or Outlook.
One universal purchase. Native on every Apple device you own, reading the same folders.
No subscription. No account. The App Store shows your local price.

Yes. MD Flow reads local files, so it works fully offline. Folders that live in iCloud or Dropbox keep syncing through those services as they already do.
