Archimedes is a Markdown and LaTeX editor built from the ground up for iPad and designed to make mathematical writing fun and easy.

Other Platforms

At its core, Archimedes is a fully-featured plain text and Markdown editor. It includes a fast syntax highlighter and provides convenient keyboard shortcuts for common actions, such as inserting images and links. With complete support for Markdown and the Format Bar floating above the iOS keyboard, Archimedes makes formatting and structuring documents elegant and easy.

# BuoyancyIn science,**buoyancy**is an upward force exerted by a fluid that opposes the [weight](https://en.wikipedia.org/wiki/Weight) of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

In Math Mode, Archimedes lets you write mathematics in a subset of LaTeX, making it an approachable LaTeX
editor. Just enter `$$`

to get started. Over 700 intuitive commands, such as
`\sqrt{a^2 + b^2}`

, help you produce stunning mathematical output. Archimedes even
autocompletes commands and intelligently matches closing braces, brackets, and parenthesis as you type.

Just getting started with LaTeX? Don't know the code for the *varproto* symbol? Just draw it!
Archimedes will recognize the symbol and insert the corresponding code for you.

As you work, a beautifully-typeset live preview of your document is always visible. You can even select a custom theme, and Dark Mode is fully supported. Themes come with various font faces.

Browse the math library to see all available LaTeX commands and their previews in one place.

Insert images from your Photos library, via the Document Camera, or by drawing sketches right inside the document.

Archimedes is the only app of its kind that supports syncing documents via iCloud with its Mac counterpart.

Working on a long document? Use the Navigator to pull up a table of contents and quickly jump between sections.

Take advantage of Magic Keyboard and keyboard shortcuts to quickly navigate the app.

Use the Find bar to find and replace text in any document.

View the character count, word count, and reading time as you work.

Share your work with the rest of the world via email, iMessage, AirDrop, and more. Export documents to the Files app in PDF or HTML formats. You can even print with AirPrint.

Archimedes is a native app built using technologies like Swift, SwiftUI, Core Animation, PDFKit, iCloud, and WebKit, and it takes full advantage of the power of iPad and iPadOS.

★★★★★ **So
Convenient!**

*This is the perfect editor for those who enjoy the simplicity of Markdown, but
need LaTeX for scientific and mathematical writing. The ability to draw symbols and have them
magically turn into escape codes will save you hours of time!*

★★★★★ **I use
this app every day - highly recommended.**

*I have recommended this to colleagues and students, even those who are not
experienced with TeX, and they are always amazed that, for a very modest price, they can load one
app and be productive right from the start. Another big positive for me is that Archimedes' rendered
PDF is quite good: clean, modern and readable.*
