MarkUp now typesets LaTeX on its own, entirely offline. Full LaTeX typesetting (Pro). Compile .tex files with a real XeTeX engine right on your device — no internet, no account, no upload. Download the support files once and everything after that works on a plane. Jump between source and page. Tap the rendered PDF to land on the line that made it, or jump from your cursor straight to the page. Search the typeset document, follow its outline, and step through pages. Write faster. Autocomplete for commands, citations, references, environments and file paths. Auto-closing brackets, a maths symbol palette, a visual table builder, and a live preview of the equation under your cursor. Catch mistakes sooner. Errors and warnings are marked in the margin beside the line that caused them, with plain-English explanations, and a code check that flags common LaTeX slips before you compile. Templates. Start from a ready-made article, paper, thesis, problem set, presentation or CV — every one compiles as-is. Save any document of your own as a reusable template, for any file type, synced across your devices (Pro). Also new. Find and replace across a whole folder, subfolder support, side-by-side version comparison with change stepping, spell-check language selection, and a clearer way to resolve iCloud conflicts.
