Markup vs Markdown.md

Markup reads and edits your Markdown beautifully — and it works with the folder of notes you already have, on your iPhone and iPad. POINT IT AT YOUR FOLDER — OR A GITHUB REPO • Open any folder of .md files from iCloud Drive or Files — the same vault you use on your Mac. Nothing to import, no lock-in. • Open a GitHub repo as a vault and read the whole thing offline. • Open several vaults and switch between them. READ LIKE A PAGE • High-fidelity rendering: syntax-highlighted code, LaTeX math, Mermaid diagrams, tables, task lists, and GitHub-style callouts. • Light / Dark / Sepia themes, adjustable text size and width, Dynamic Type. • Wikilinks, backlinks with context, a per-document outline, and tags. FIND ANYTHING • Full-text search with tag: and path: filters; fuzzy Quick Open. EDIT WITH EASE • A focused Markdown editor with smart lists, auto-closing brackets, table formatting, and inline [[wikilink]] and #tag autocomplete. • Insert images straight into your vault. Export or share as PDF, HTML, or Markdown. iPAD • Open documents in tabs; edit with a live rendered preview beside the source. • Hardware-keyboard shortcuts. HTML, TOO • Open and read .html and web bundles, with scripts off by default for safety. PRIVATE BY DEFAULT • No account required, no telemetry, no tracking. Your notes stay on your device and your iCloud. Signing in to GitHub is optional and only used to fetch the files you ask for. English and 简体中文, switchable in-app.

Markdown.md is a beautiful, blazing-fast Markdown reader, editor, and library — built to work 100% offline, with no account and no tracking. Whether you live in READMEs, technical docs, meeting notes, or your own writing, every document renders cleanly and opens instantly. BEAUTIFUL RENDERING Headings, bold, italics, tables, task lists, blockquotes, and nested lists all render with care. Fenced code blocks get real syntax highlighting for dozens of languages. Mermaid diagrams — flowcharts, sequence, Gantt, class, and state — and Excalidraw sketches render inline. SVG graphics, LaTeX math, footnotes, images, and embedded video links are supported too, along with YAML frontmatter. MAKE READING YOURS Choose a reading font and a separate code font from the system faces plus 100+ bundled typefaces, with a searchable picker and favorites. Fine-tune text size, line spacing, and content width (Narrow, Normal, Wide). Pick from 14+ built-in themes — GitHub, Solarized, One Dark, Dracula, Nord, Catppuccin, Tokyo Night, Gruvbox, Rosé Pine, Ayu, Everforest, Night Owl, Kanagawa, Monokai — each in light and dark, or craft your own with a color picker. Set backgrounds like Paper or Sepia, and override the theme per document. Move through long files with a searchable outline and a scrubber, find text with a live match counter, flip to raw source, and pick up right where you left off. A REAL EDITOR, BUILT IN Write and edit with a syntax-highlighted editor and a full formatting toolbar: headings, bold, italic, strikethrough, inline code, bullet/numbered/task lists, blockquotes, indent and outdent, plus one-tap insert for links, images, tables, and code blocks. Undo and redo, autosave, live preview, and word, character, line, and reading-time stats. ORGANIZE YOUR LIBRARY Keep everything tidy with folders, tags, and full-text search. Sort by name, created, or last opened, filter by folder or tag, and switch between list and grid. Rename, duplicate, move, and delete with ease. IMPORT FROM ANYWHERE Open files from the Files app, the Share Sheet, and AirDrop, paste a link to any Markdown file, or browse public GitHub repositories by owner/repo or URL — then read them offline. EXPORT & SHARE Turn any document into a polished PDF, HTML, Markdown, or plain-text file, each with a preview before you share. Back up and restore your entire library too. EVERYTHING IN ONE PLACE The attachments panel automatically gathers every link, image, code block, diagram, video, and footnote into one searchable view — copy links, view code, or save images to Photos or Files. HIGHLIGHTS & BOOKMARKS Highlight passages in five colors, add notes, and jump straight back to them anytime. PRIVATE BY DESIGN Rendering happens on-device with all assets bundled — no CDN, no account, no tracking. Turn on iCloud to sync documents, folders, tags, bookmarks, and appearance across devices, or keep everything local. Lock the app with Face ID or Touch ID. BUILT FOR iPHONE, iPAD & MAC Enjoy a sidebar and split view on iPad, and run it on your Mac. Free to use with up to 10 documents and 20 bookmarks.
