MarkUp — Text & Math Editor

MarkUp is a writing app for notes, research, and long-form work. Edit Word documents with a true page layout, write in Markdown with live preview, or typeset a full LaTeX thesis with a real XeTeX engine that runs entirely on your device. For students, researchers, and technical writers — with the same features on iPhone, iPad, and Mac, in one universal purchase.

• Table of contents, captions and cross-references, citations with a works-cited list
• Footnotes and endnotes, comments with replies, and tracked changes
