MarkD - Markdown Viewer app analytics for October 23

The Markdown reader for developers who think on the go. Open any .md file — README, design doc, API spec — and see it rendered in seconds. Code blocks highlighted in 40+ languages, Mermaid diagrams drawn automatically, HTML rendered cleanly. No setup, no clutter. iPhone in your pocket, ideas in your head. MarkD turns waiting time at the bus stop, the elevator, the coffee line into useful reading time. — Clean Markdown Rendering Headings (H1–H6), bold, italic, strikethrough, tables, blockquotes, links, images, ordered and unordered lists, checkboxes — all standard Markdown syntax fully supported. Both light and dark modes render with comfortable typography. Long documents scroll naturally in one continuous flow, with no screen transitions interrupting your reading. Code Syntax Highlighting Swift, Objective-C, Python, JavaScript, TypeScript, Go, Rust, Java, Kotlin, C, C++, C#, Ruby, PHP, Shell, SQL, HTML, CSS, JSON, YAML, and 40+ more languages are supported. Code blocks are highlighted with language-appropriate colors so structure is clear at a glance. Dark mode applies a low-fatigue color theme automatically. Mermaid Diagrams Mermaid code blocks inside Markdown are automatically detected and rendered as visual diagrams. Flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, and Gantt charts are all supported. Especially useful when reading system design documents, API flow docs, or database schemas. Folders & Tags Organize saved documents into folders and attach tags for easy retrieval. Filter by file type (Markdown, HTML, Swift, Python, JSON, and more) or search by title to instantly find any file. Use favorites to keep frequently viewed documents close at hand. Wide File Format Support Beyond .md and .markdown, MarkD opens .html, .swift, .py, .js, .ts, .go, .rs, .java, .kt, .c, .cpp, .cs, .json, .yaml, .yml, .txt, .sh, .rb, and virtually every text-based file format developers work with daily. Both the file extension and content are analyzed to automatically select the best rendering method. Files App Integration Long-press any file in the iOS Files app, choose "Open in MarkD," and it's imported instantly. Works with iCloud Drive, local storage, and third-party cloud storage. Duplicate files are never saved, keeping your library clean.

Reading Info & HTML Support Word count and estimated reading time are automatically calculated when you open a document. HTML files are rendered in a built-in web view, with dark mode meta tags injected automatically. — Built for - Developers who frequently read READMEs and open source documentation - Engineers who want to view Markdown files from GitHub or GitLab on mobile - Writers who draft technical blog posts in Markdown and want to preview them - Team members who reference wikis, API docs, and design documents on the go - Anyone who wants to read documents containing code in a clean, focused environment MarkD is focused purely on reading documents well — no unnecessary features, no clutter.
