md.too

Application md.too is a minimalist markdown viewer for iPhone and iPad. It opens .md files, renders them, and lets you read and copy. That is the whole product.

What it renders:

• Headings, lists (including GitHub-style task lists with [ ] / [x]), block quotes, thematic breaks, and inline emphasis (bold, italic, strikethrough, underline).

• Code blocks with syntax highlighting for about 40 languages: Swift, C/C++/C#/Objective-C, Java, Kotlin, Scala, JavaScript, TypeScript, Python, Rust, Go, Ruby, PHP, Dart, Lua, Perl, R, Julia, Haskell, OCaml, F#, Elixir, Clojure, Groovy, SQL, GraphQL, Dockerfile, Makefile, TOML, INI, YAML, JSON, XML, HTML, CSS, Bash, PowerShell, Markdown.

• Tables, including inline images inside table cells.

• Inline images loaded from any HTTPS URL, with explicit width/height attributes (GitLab-style {width=N height=N}).

• A small but useful LaTeX subset in $…$ and $$…$$: Greek letters, super- and sub-scripts, common operators, simple fractions, and basic display math.

• Selectable, copyable text. Code blocks and tables get a one-click copy button.

• Light and dark theme — follows the system, or pick one explicitly.

• Export the rendered document to a paginated PDF, with images embedded.

What it deliberately does not do:

• No editor, no live preview/edit split, no autosave. Read-only by design.

• No HTML rendering or WKWebView. Pure native UIKit/SwiftUI.

• No file tree, no tabs, no command palette.

• No third-party packages. The most popular JavaScript Markdown library, marked, lists about 636 transitive dependencies and roughly 38,980 lines of code on its public dependency graph. md.too ships zero dependencies. Every package you do not pull in is a supply-chain risk you do not inherit.

Privacy:

The application does not collect or transmit any personal data. The only network traffic is fetching inline images you reference by URL.
