Texifier : LaTeX editor 4+

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 on an equal footing 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, 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.
