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.
