Frequently Asked Questions

Is Martypex free?

Yes. You can write and compile unlimited Typst and Markdown documents for free, with a live preview and watermarked PDF export. A one-time Pro unlock removes the watermark and adds PNG, SVG, and custom-DPI export, full custom app theming, and a snippet library. Pro is a single purchase, not a subscription, and it is shared across your Family Sharing group.

Do I need an account or an internet connection?

No account, ever. All Typst and Markdown compilation happens on your device, so writing, compiling, previewing, and exporting all work offline. The only thing that uses the network is the first download of an @preview package or an add-on font; once fetched, those are cached and work offline too.

Does my writing leave my device?

No. Your documents, their contents, and your file and project names never leave your device. There is no cloud upload and no tracking. See the Privacy Policy for the full details.

What is the difference between Typst and Markdown here?

Typst gives you full typesetting control: precise layout, figures, cross-references, citations, and Typst’s own math syntax. Markdown is faster to write for prose and notes, and Martypex compiles it to the same clean paginated PDF. You can choose a default in Settings and open either kind of file at any time.

Is this LaTeX?

Not exactly. Typst is a modern alternative to LaTeX with a friendlier syntax, and it is what powers Martypex. In Markdown files you can still write LaTeX-style math, which Martypex converts for you, so equations you already know how to write will just work.

Can I use Typst packages?

Yes, the full @preview registry. Import a version-pinned package such as #import "@preview/cetz:0.2.2" and Martypex fetches it from the official Typst registry, caches it on device, and compiles, automatically, including any packages it depends on. Only the first fetch of a given package needs a connection; after that it works offline and reproducibly, forever. Packages, even those with WebAssembly plugins, are free. See Packages.

Can I add my own fonts?

Yes. Martypex bundles Typst’s default fonts, and the Fonts manager lets you download the New Computer Modern text weights (free), import your own .ttf/.otf/.ttc files, or install families from Google Fonts (the last two are Pro). See Fonts.

Can I use a hardware keyboard?

Yes. Pair one and every command, from Bold and Compile to Export and Toggle Source/Preview, gets a shortcut, all of them rebindable in Settings → Keyboard Shortcuts. On iPad, hold Command for an on-screen HUD listing what’s available. There’s also a searchable Command Palette (⇧⌘K) for running any command, symbol, snippet, or file by name. See Keyboard Shortcuts and Command Palette.

Can I change how Martypex looks?

Yes, with Pro. Beyond the built-in themes, System, Solarized, Dracula, and more, you can create, customize, import (from VS Code, RStudio, or TextMate), and export your own full-app theme, recolouring both the editor and the app’s own interface. See Themes.

Can I edit files other than Typst and Markdown?

Yes. Martypex also opens .svg and .html files as first-class documents, with syntax-highlighted source and a live rendered web-view preview, no Typst compilation involved. See SVG & HTML.

Does it sync with iCloud?

Your documents are ordinary files. Save them in iCloud Drive through the Files app and they sync across your devices like any other file. Martypex follows the system’s iCloud behaviour rather than running a sync service of its own.

Which devices and iOS version are supported?

Martypex is a universal app for iPhone and iPad, running on iOS 26 and later.

How do I report a bug or request a feature?

Use Settings → Export Diagnostics to gather a scrubbed report, then send it to support@caffeinatedmath.com or open an issue from the Support page.
