Edit and typeset LaTeX, Plain TeX and Markdown on your iPad or iPhone, no internet connection required, using Texifier, formerly known as Texpad. Texifier is a LaTeX editor designed for straightforward navigation, editing and typesetting of projects of any size. Open a LaTeX root file, and Texifier will scan it, open any referenced files, extract the document structure for display in the outline view, and configure the typesetter according to the packages and tools used by your document. Texifier's editor comes with a choice of themes, syntax highlighting, autocomplete of commands, including those defined in your document, and autofill for \cite commands, \ref commands and others. The powerful sidebar can show you a summary of your document structure allowing you to navigate through large multi-file projects with ease. Additionally Texifier's outline lists all labels, figures, tables, todos and it contains a powerful search function that can search and replace across your entire project using either normal text searches or regular expression searches. TexpadTeX - Texifier's internal, no internet connection required, typesetter comes with PGF drivers, Native Fonts extensions, a Unicode and more, allow it to support almost any LaTeX package available. TexpadTeX also integrates a BibteX tool and a Makeindex compatible indexer for documents that require those tools. The integrated bundle manager takes care of downloading, installing and updating LaTeX packages for you, giving you access to almost the entire LaTeX ecosystem without using any more space on your device than needed. TexpadTeX can run in Live mode, updating the output as you type, so you never need wait for a typeset to finish again. For the rare cases of documents that are not compatible with TexpadTeX, you can use our free cloud typesetters. This is fully integrated into Texifier so press typeset, and Texifier will run the typeset in the Cloud, presenting the results just as if they were typeset on your device. After all typesets, any errors in your document are organised in a table of issues. Tap on an issue to jump directly to the offending line of LaTeX source, or the line in the original log if you wish to read the original output. Texifier works well with Files App, allowing you to store and work on your documents wherever you wish. On top of that Texifier Connect is directly integrated into Texifier for working across devices and collaborators. Texifier supports Markdown along with LaTeX. Edit your document in Texifier's syntax highlighting editor, browse the document by outline, then when you press Typeset, the document will be transparently converted and typeset by LaTeX (using a standard template), giving you the informal ease of Markdown with LaTeX's ability to create beautiful and high quality PDFs. Likewise Plain TeX users can edit and typeset their documents in Texifier. Features: - Universal binary for iPhone and iPad, optimised for the latest generation of devices. - Typeset LaTeX to PDF on your iPad and iPhone without need for an internet connection - Support for LaTeX, Plain Tex and Markdown - Navigate easily through even the largest projects using the Outline view - Search all files by string or regex with the global search view - Browse the typeset errors and warnings either as a raw log, or with the errors and warnings table view. - Texifier's editor autocompletes commands, and autofills commands such as \ref{...} or \cite{...} - Use iOS Files app to edit documents in any storage that supports file or folder access - Instant Live typeset using Texifier's built in TexpadTeX typesetter - The onboard typesetter supports virtually any LaTeX package or font, including, but not limited to: Beamer, Tikz, Fontspec, Koma Script, e-TeX, graphicx, pgfplots, AMS, RevTeX, Babel, Bibtex and Indices. - Free typesetting through our secure cloud servers gives you access to all packages in the latest TeXLive distribution.

Verdict
The clearest difference is price: Highlights at Free against Texifier's $29.99. Highlights also leads on update cadence (fortnightly vs every 2 months) and rating (4.5 vs 4.3). Texifier's advantage is in-app purchases (none vs 3). On review sentiment, ratings volume and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Highlights is free to download; Texifier costs $29.99 up front. Highlights sells 3 in-app purchases, starting at $4.99 per month. Texifier asks for nothing beyond the download.
Highlights holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 690 and 1.6K respectively. Written reviews complicate that: 57% of Texifier's written reviews are positive against 53% of Highlights's, so the app with the better star average is not the one people write more warmly about.
Texifier ships an update every 2 months, Highlights fortnightly. Both last shipped on September 28, 2026.
