Markdown Viewer Mobile vs Just a Markdown Viewer

MarkdownViewer is a distraction-free reader for .md files on iPhone and iPad. Open a file from Files, AirDrop, or a shared link; or sync an entire documentation repository from GitHub and read it offline. Just exploring? The app ships with a curated library of example documents covering every feature below — sync it with one tap from the "Try it" card on the library screen. RICH RENDERING • Full CommonMark + GitHub Flavored Markdown • Mermaid diagrams rendered inline • LaTeX math (inline and display) via KaTeX-compatible engine • Syntax-highlighted code blocks across 190+ languages • GFM tables, task lists, footnotes, strikethrough • GitHub-style admonitions (NOTE, WARNING, TIP, CAUTION) READING COMFORT • Material 3 design with light, dark, and sepia themes • Adjustable font size, reading width, and line height • Immersive scroll — the app bar fades away as you read • Table of contents drawer with one-tap navigation • In-document search with match counter • Reading-position bookmark — resume exactly where you left off • Keep-screen-on toggle for long-form reading • Reading time estimate BRING YOUR OWN DOCS • Sync any public GitHub repository with a single URL • Private repos supported via a personal access token (stored in the iOS Keychain — never in the app's database) • Incremental re-sync — only changed files download • Re-sync or remove a synced repo from the drawer EXPORT AND SHARE • Export any document to PDF with mermaid diagrams preserved • Share the raw markdown or a rendered PDF via the system share sheet PRIVACY BY DESIGN • No accounts, ever • Zero telemetry by default • Crash reporting is opt-in and excludes document content, file paths, and tokens • The only network traffic is to GitHub when you explicitly sync Made in the open on GitHub.

Just a Markdown Viewer does exactly one thing: it shows you markdown files, beautifully. No editor, no preview pane bolted onto a text editor, no sync service or account required. Open a .md file and read it in a clean, centered, monochrome reading column, the way a document should look. WHAT IT DOES • Renders headings, lists, tables, code blocks, quotes, links, and task lists • One toggle between formatted view and raw source (⇧⌘R) • Native text selection everywhere, so you can select and copy freely • Light mode, dark mode, or follow the system • Opens .md, .markdown, .mdown, and .mkd files, plus plain text • On Mac: files open as tabs, Chrome-style, and you can drag a tab out or merge tab groups • On iPhone and iPad: opens straight from the Files app WHAT IT DOESN'T DO • Edit files. That's the point • Collect data • Touch the network If you just want to READ markdown, this is the app.
