Temporal Mode

Don’t just plot it.
Watch it change.

Time becomes part of the equation. Play through a changing function, pause on a moment, or step through it until the behavior makes sense.

Set the pace.
Play, pause, step, change speed, and loop supported graphs.
Compare in time.
Inspect synchronized graph fields at the same temporal position.
Look closer.
Use live readouts, Trace, and supported slices and contours.
Explore temporal graphing

Complex 3D

A new perspective
on the complex plane.

Turn a complex-valued function into a surface you can inspect. Explore its magnitude, argument, real part, or imaginary part—and see structure that an expression alone can hide.

Find the structure.
Explore roots, poles, branch behavior, and singularities.
Change your view.
Rotate, zoom, and inspect supported slices and contours.
Connect surface and path.
Move between Complex 3D surfaces and Complex 2D traces.
Explore Complex 3D

CAS + Python

Explore visually.
Work precisely.

Keep exact expressions, tensor objects, and numerical experiments close to the graph. Different ways to follow the problem further.

Computer Algebra System

Keep the exact answer.

Simplify, factor, expand, solve, differentiate, integrate, and evaluate supported limits. Review symbolic results without losing the structure of your work.

Local Python workspace

Make the next calculation your own.

Write a numerical script, run it locally, inspect the output, and revise it. Matrix, Tensor, and compatible dataset handoffs keep computation connected.

Math-focused sandbox: no network, file browsing, package installs, or subprocesses.

Callie Pro for Mac

The mathematical workstation,
now native on Mac.

The same mathematical foundation as Callie Pro for iPad, shaped for desktop windows, keyboard and mouse workflows, larger problems, and higher compute ceilings.

Built for the desktop

A Mac interface, not an iPad window.

Use a native Swift and SwiftUI desktop shell with collapsible workspace navigation, menu commands, keyboard shortcuts, mouse and trackpad interaction, resizable workspaces and inspectors, and Mac-native Save and Export workflows.

Download on the Mac App Store

More room for the hard stuff

Scale the workspace with desktop hardware.

Work with Matrix editing up to 128 × 128, tensors up to rank 8, larger statistics datasets, higher graph sample limits, 3D mesh levels up to 257, and adaptive Temporal 3D quality under bounded resource policies.

Mac Python is bundled with Callie Pro. It does not depend on Homebrew or the system Python, and it keeps the same local sandbox model.

The rest of the work,
right here.

Go from a question to a graph, a calculation, and a result you can use—without switching tools.

For the questions worth following.

From coursework and teaching to engineering calculations and mathematical exploration.

The practical details

Mac or iPad.
Still your workspace.

Your graphs, calculations, tensors, documents, and local Python work stay on your device.

What is Callie Pro?

Callie Pro is a native mathematical workstation for Mac and iPad. It brings graphing, Temporal Mode, Complex 2D and 3D, CAS, Tensor, Matrix, local Python, Stats, Catalog, Trace, Table, and export workflows into one app.

Where can I use Callie Pro?

Callie Pro is available as a native Mac app and as an iPad app. The iPad edition requires iPadOS 16 or later; current Mac compatibility is listed on the Mac App Store.

What can I animate with Temporal Mode?

Supported temporal graph types include functions, parametric paths, polar graphs, complex paths, and 3D surfaces. Play, pause, step, adjust playback speed, and loop supported graphs to inspect how they change.

What does a Complex 3D surface show?

Enter f(z) and view its magnitude, argument, real part, or imaginary part as a height surface over the complex plane. Rotate, zoom, trace, and use supported slices and contours to inspect the structure.

What does the Tensor workspace support?

Tensor supports rank-N real and complex tensors, indexed notation, Einstein summation, contractions, transformations, metric operations, tensor calculus, and numerical differential-geometry workflows.

Is the Python workspace a general-purpose Python environment?

No. It is a local, math-focused sandbox. On Mac the Python runtime is bundled with Callie Pro and does not depend on Homebrew or the system Python; the same sandbox boundaries still apply.

Do I need an account?

No account is required. Graph documents and calculations are local to your device, and Python scripts run locally inside the calculator sandbox.

Is this the same app as Callie?

No. Callie is the everyday calculator. Callie Pro is a separate Mac and iPad app for advanced graphing, symbolic math, tensor and matrix work, numerical computation, and visual exploration.
