Markup vs Just a Markdown Viewer

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.

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.
