Markflow — Markdown Reader

The markdown reader you've been missing.

Markflow opens .md files from Files, Mail, Safari downloads, or the share sheet and renders them properly. GitHub-flavored markdown, syntax-highlighted code, mermaid diagrams, tables, task lists, and more.

Originals are never touched. Edits live in memory until you explicitly Save, Save as New File, or Share a copy.

WHAT YOU CAN DO

• Open any .md, .markdown, or .mdown file from any app • Read with a clean, native preview • Edit with a markdown toolbar above the keyboard. Bold, italic, headings, lists, links, images, code, quotes, all one tap away. • Pinch to zoom in both Preview and Edit • Export an edited copy via the system share sheet • Tap Create to start a new blank file, or "Welcome to Markflow" for a full feature tour

WHAT IT RENDERS

• Headings, lists, blockquotes, links, images • Syntax-highlighted code blocks • Mermaid flowcharts and diagrams • GitHub-flavored markdown tables • Task lists with checkboxes • Inline images (absolute URLs)

PRIVACY

Markflow makes zero network requests and collects zero data. No accounts. No login. No analytics. No tracking. No ads. The renderer is a sandboxed local file with a Content Security Policy that blocks all remote resources.

Your files stay on your device.

DESIGN

Built native with SwiftUI and the Liquid Glass nav bar. Light and dark mode. Adaptive home screen. Stock Apple Human Interface Guidelines throughout.

WHO IT'S FOR

• Writers who keep notes in markdown • Developers reading READMEs and docs on the go • Anyone who's been emailed a .md and had nowhere to open it • People who want a markdown reader that does one thing well
