Marko vs MD Viewer

Marko is a fast, native Markdown viewer for iPhone and iPad. Open any .md file and read it the way it was meant to look, with real typography, syntax-highlighted code, GFM tables and task lists, Mermaid diagrams, and KaTeX math. Everything renders on your device with no network access, so your documents never leave it. Marko is a viewer, not an editor. It never changes your files. Open Markdown straight from the Files app, or share it in from Mail, Safari, or any other app, and read it full-screen with an outline, find in page, and adjustable text size. It is built for the Markdown you didn't write by hand, too: the .md that AI assistants and coding agents produce, generated READMEs, and agent output. DOCUMENT INTELLIGENCE, ON DEVICE Summarize a long document, ask questions about it, or explain a selected passage, all processed on your device with Apple Intelligence. Nothing is sent to a server. (Requires a device with Apple Intelligence.) HIGHLIGHTS - Native Swift and SwiftUI app for iPhone and iPad. Not a web app. - Renders fully offline. Your documents never leave your device. - Opens Markdown in place from Files, and via the share sheet from other apps. - Outline, find in page, and text zoom. - Light, Dark, and System themes. - Universal purchase: buy once, use on Mac, iPhone, and iPad. Marko collects no data. It has no analytics, no accounts, and makes no network requests of its own. Free. Requires iOS or iPadOS 18 or later.

MD Viewer shows Markdown files as clean, readable documents. READ FIRST Every file opens in reading mode. Headings, lists, quotes, tables, code blocks, links and images are rendered natively with the system fonts, your text size and your accent colour. Text is selectable, links open in your browser, and the layout adapts from a phone to a full Mac window. EDIT WHEN YOU WANT Tap Edit to change the source. In Formatted mode the Markdown is styled as you type, with headings large, emphasis rendered, code monospaced and the syntax dimmed, plus a formatting bar for headings, bold, italic, strikethrough, code, links, images, lists, quotes, code blocks, tables and rules. Prefer the raw source? Text mode is a plain editor. Either way the file stays plain Markdown, saved automatically, with undo. YOUR FILES, WHEREVER THEY ARE Files app, iCloud Drive, Finder, Dropbox and other providers, Share, Open With, drag and drop. Multiple windows on iPad and Mac. Keyboard shortcuts including ⇧⌘E to toggle editing. PRIVATE BY DESIGN No servers, no analytics, no ads, no tracking. Your documents never leave your device; the only network use is loading images your own document links to. Supports CommonMark plus tables and strikethrough. Requires iOS 17, iPadOS 17 or macOS 14 or later.
