LaTeX Help
Math Symbols & TeX Commands
Free · Designed for iPad. Not verified for macOS.
Completely rebuilt for iOS 27. Find any LaTeX symbol by name, command or character, copy it with one tap, and keep the ones you use most a tap away.
Find the LaTeX command for any symbol in seconds. Tap it, and it's on your clipboard, ready to paste into your document.
LaTeX Help is a pocket reference for writing math in LaTeX. It covers the symbols you need and the formatting you keep forgetting, without the bloat of a full manual.
FIND IT FAST
- Search by name ("integral"), by command (\int) or by the character itself (∫)
- Browse symbols by category: Greek letters, operators, relations, arrows, integrals and sums, delimiters, accents, functions, set theory and logic, and more
- Tap any symbol to copy its command. Long-press to copy it wrapped in $…$
KNOW WHAT IT NEEDS
- Every symbol shows the package it requires, such as amsmath or amssymb, with the \usepackage line ready to copy
- Related symbols are shown side by side, so you pick the right arrow the first time
