Formula Kit vs TeXAnt

Type, edit and export LaTeX formulas in one app: change a formula right in the preview or edit the LaTeX source itself; photos, images and handwriting all turn into editable code; 544 templates, a 258-symbol keyboard, live KaTeX rendering and one-tap high-res PNG / LaTeX / MathML export. Whether you are writing academic papers, preparing lesson notes, or organizing science and engineering notes, you can input, edit and export formulas in one app. Core Features • Preview editing and LaTeX code editing: the preview area is the editing area. Tap a formula to change it on the spot — what you see is what you get; you can also edit the LaTeX code directly. • Formula recognition: take a photo, pick one from your photo library, or write by hand — all are recognized as LaTeX code automatically. • 258-symbol keyboard: a custom keyboard built for formula input, with a clearly organized symbol panel (8 categories, 258 symbols: common, arithmetic, Greek letters, structures, arrows, functions and more), precise cursor dragging and LaTeX command autocomplete — much faster input. • One-tap high-res PNG and LaTeX / MathML export: save a formula as a high-resolution PNG in one tap (no watermark with Pro); export LaTeX, MathML, HTML or SVG code for papers, web pages and slide decks. • 544 formulas, live preview: 544 built-in formula templates across 14 subjects including math, physics, chemistry and computer science, ready out of the box; rendered in real time with the KaTeX engine so you see results as you type, with instant syntax hints; one-tap favorites and custom categories keep everything organized. • History and full-screen preview: editing history is saved automatically and easy to browse as thumbnails; full-screen preview appears automatically after you copy a formula. Why Formula Kit • Lightweight and fast — quick launch, smooth rendering • iPhone, iPad and Mac • Core features are free; upgrade to Pro to unlock full recognition, watermark-free export and unlimited favorites (yearly subscription or lifetime purchase) Who it is for • Students (high school / university / graduate) • Teachers and professors • Researchers • Engineers and technical writers • Anyone who needs to type mathematical formulas Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

TeXAnt lets you write LaTeX documents, compile them and read the PDF, while managing your bibliography and versions in the same app. No account or extra software required. The embedded LuaTeX engine compiles articles, books, book chapters, theses, presentations and all your scientific work on your device: no server queue, no internet. COMPILATION ENGINE • LuaTeX and HarfBuzz-powered LuaHBTeX, with correct typesetting for complex scripts. • Smart multi-pass compilation resolves bibliography and cross-references and builds index, glossary and nomenclature automatically. • Multi-file projects: chapter files added with \include are compiled together with the main document. PACKAGE AND FONT MANAGEMENT • When a compile hits a missing package, TeXAnt reads the error, installs it from CTAN mirrors with one tap and resumes compiling. • Install packages yourself anytime: search the Package & Font Manager, see dependencies, install without waiting for a compile. • Ready-made install sets and TeX Live collections. • Same flow for fonts: just call them with \setmainfont or \fontspec. ADVANCED CODE EDITOR • Rich syntax highlighting for LaTeX, BibTeX and Markdown. • Smart autocompletion: command, environment, \cite{} and \ref{} suggestions. • Instant math preview while the cursor is on a formula. • Live linter: catches bracket, environment and syntax errors without compiling. • Vim mode, spell checking and a symbol/command keyboard bar for touch screens. PDF PREVIEW AND SYNCTEX • Bidirectional SyncTeX: tap a point in the PDF to jump to its source line, and back. • Built-in PDF reader: text search, two-page view and thumbnail grid. SMART INPUT TOOLS • Math OCR: take a photo of a formula and TeXAnt turns it into LaTeX. Recognition runs on device; your image is never uploaded. • Visual formula editor: edit formulas visually and get the LaTeX code instantly. AI ASSISTANT • Connect OpenAI, Anthropic, Gemini, Nvidia or OpenRouter with your own API key. • Have it write, explain, debug or optimize code, and apply the fix with one tap. • Optional: only the text you select is sent to the provider you connect. CLOUD STORAGE • Sync and back up your projects with iCloud Drive, Google Drive, Dropbox, OneDrive, Box, Yandex Disk or Amazon S3. BUILT-IN GIT • Clone repositories from GitHub, GitLab, Bitbucket and Overleaf; commit, push, pull and browse history. BIBLIOGRAPHY MANAGEMENT • Edit your references in the Bibliography Manager. • Import records from Zotero, Mendeley and EndNote into your project as .bib. AND MORE • 16 project templates: thesis, article, book chapter, exam, Beamer presentation, CV, lecture notes and more. • Languages template: a ready-to-write document in 11 languages such as Arabic, Chinese, Japanese and Hindi. • Equation editor, figure inserter and Beamer slide tools. • Navigate sections, figures, tables and references in the Structure panel. • Snippets panel to quickly insert and manage frequently used LaTeX commands. • Project-wide search with regex, and replace all. • Printing; ZIP import/export, compatible with Overleaf and desktop projects. • Light and dark themes, three-panel layout, a 25-language interface and right-to-left (RTL) support.
