MDQuickView

Reads Markdown beautifully on iPhone: syntax-highlighted code, KaTeX math, Mermaid diagrams and tables. Private by design — no accounts, no tracking.

MDViewer is a fast, private Markdown viewer for iPhone. Open any .md file from the Files app — or browse folders you choose — and read it beautifully rendered.

RENDERING • Syntax highlighting for 40 languages (Shiki) • LaTeX math, inline and block, via KaTeX • Mermaid diagrams — flowcharts, sequence diagrams and more • Tables, task lists, blockquotes and everything else Markdown has • Six themes: GitHub Light / Dark, Solarized Light / Dark, Dracula, Nord • Adjustable text size, and pinch to zoom

FILES • Open .md files straight from the Files app, iCloud Drive or other apps • Grant a folder once and browse its Markdown files in the app • Remembers your last document and granted folders

READING • Find in document • The toolbar fades away while you read and comes back with a tap

PRIVATE BY DESIGN • No accounts, analytics, tracking or ads — your documents never leave your iPhone • Only reads the files and folders you choose • Remote images load only if you allow them (Ask, Always or Never)

MDViewer is open source (MIT). It is a fork of the original MDViewer by Masanori Sakai.
