MarkUp - Word, Markdown, LaTeX

MarkUp is a writing app for notes, research, screenplays, and long-form work. Edit Word documents on real pages, write Markdown with a live preview, or typeset a full LaTeX thesis with a real XeTeX engine that runs entirely on your device. Work with CSV, JSON, YAML, HTML, Rich Text, and Fountain files too, and let your files work together, with the same features on iPhone, iPad, and Mac. Made for students, researchers, and writers: draft a thesis in LaTeX, take notes in Markdown, and hand in a Word document, all in one app.
