Typeproof – Markdown Read/Edit
Print-quality typesetting
$3.99 · Designed for iPad. Not verified for macOS.
Now optimized for iPhone Duo — read, edit, and live-preview on the foldable display. Plus dual-pane editing, full keyboard shortcuts on iPad, and the new SongYa theme.
Typeproof is a Markdown reader and editor built for people who care how text looks.
On your iPhone, iPad, and the all-new iPhone Duo, Typeproof renders Markdown with print-level fidelity — refined paragraph breaking, publication-grade CJK typesetting, and real LaTeX mathematics. And when you need to change a word, you can edit right where you read.
BUILT FOR IPHONE DUO
• Fully optimized for the foldable display — read, edit, and live-preview in closed, half-open, or fully expanded form.
READ WITH CONFIDENCE
• Faithful Markdown rendering: tables that keep their alignment, fenced code blocks, footnotes, strikethrough, task lists.
• Knuth–Plass line breaking for beautifully justified, evenly spaced paragraphs.
• CJK typography rules: dedicated punctuation and line-breaking rules for Simplified Chinese, Traditional Chinese and Japanese, including kinsoku (禁則処理) — no more stray punctuation at line starts.
REAL LATEX MATHEMATICS
• Inline and display LaTeX: inline formulas share the text baseline and flow with the words around them; display formulas are centered, just like in a typeset book.
• Matrices, piecewise functions, alignment, accents, operators and the entire Greek alphabet — in either position.
MORE THAN PROSE
• Images in SVG, PNG and JPEG, placed inline or centered — including fully animated SVGs, played in full.
• Tables, syntax-highlighted code, numbered and tappable footnotes, GitHub-style alerts, and full emoji support.
• Audio and video links in your documents play right inside the app.
• Everything is selectable — copy any text, formula or code with a tap.
• Handles large documents with ease — Markdown files up to 200 MB open and render smoothly.
EDIT WHERE YOU READ
• Full source editing — edit the Markdown source directly, save, and instantly preview the result with the same print-quality typesetting.
• Open local Markdown files and folders; everything you change stays on your device.
FROM ANYWHERE ON THE WEB
• Paste a link to any Markdown file on the web — GitHub repos and gists, Hugging Face model cards and datasets, personal blogs, documentation sites, or any raw .md URL — and download it for offline reading and editing.
• Note: the downloaded copy lives on your device — edits are not synced back to the remote file, so upload it yourself when you're done.
STAY ORGANIZED
• Outline tree — jump to any heading in long documents instantly.
• Tabs — keep multiple documents open at once and switch in a tap.
• Reading themes for day and night, easy on the eyes during long sessions.
EXPORT & SHARE
• Export to PDF and PNG, preserving the typeset layout exactly as you see it — ready to share, print, or archive.
PRIVACY BY DESIGN
• No account. No sign-up. No tracking. Your documents never leave your device.
Whether you're reviewing a README, studying lecture notes full of formulas, or polishing documentation across three languages, Typeproof makes Markdown look the way it deserves.
