Features

TYPE IT, SEE IT TYPESET

The live preview shows your formula as you write – right below it on iPhone, next to it on iPad, and on iPhone Duo half open, right on the other half. Or view it full screen, free of distractions. Fractions, integrals, sums, matrices, cases and chemistry with \ce are typeset cleanly, even offline.

BUILDING BLOCKS AT HAND

  • Above the keyboard: fraction, root, superscript and subscript, Greek letters, sums and integrals, relations, arrows, brackets, matrices and environments
  • Brackets close themselves
  • Return after \begin{…} adds the matching \end{…}, and lists continue with the next \item
  • Syntax highlighting for commands, math, environments and comments

WHOLE DOCUMENTS, TOO

Put formulas in text with $…$, or write a whole document with \section, lists, tables and numbered equations – the preview typesets it beautifully, with title and sections. Your own \newcommand macros work too.

REAL .TEX FILES

Your formulas are plain .tex files in the Files app under “On My iPhone › Texlet”. Open .tex files from iCloud Drive or other apps and edit them right where they are. Copy the LaTeX code with one tap.

ORGANIZED YOUR WAY

  • Every formula as a typeset thumbnail on the home screen
  • Folders with their own color and icon
  • Pin what matters, sort by date, name or your own order
  • Search, find and replace, printing and a LaTeX guide with examples
