Texlet vs Caratify

Write formulas in LaTeX and see them typeset right away. Texlet opens in an instant – no account, no setup, no internet needed. For homework, lecture notes, slides, theses and every equation that should look good. 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.
