Test loops, functions, roots, integration approaches, and calculator-style workflows.
Use a small script when the calculation outgrows a formula.
Callie Pro includes a protected local Python workspace for visible, editable numerical scripts and calculator-style math experiments on iPad.
It is intentionally restricted: the workspace is for local numerical exploration, not networking, package installation, file browsing, or subprocesses.
$2.99 one-time purchase in the U.S. App Store.

Keep the script visible and editable.
Write a numerical experiment directly in the editor, run it locally, inspect the output, and revise the calculation without hiding the logic behind a single button.
Review printed values and errors beside the script that produced them.
Keep a calculation readable enough to adjust and run again.
Use a deliberately limited local sandbox.
The Python workspace cannot access the network, browse files, install packages, or run subprocesses. Those boundaries keep it focused on math inside Callie Pro.
Pair scripts with native math tools.
Use CAS for exact structure, Matrix and Stats for dedicated operations, Catalog for constants, and graphing for visual inspection before or after a script.
Run a visible, bounded numerical experiment.
Write the script, run it locally, inspect output beside the source, and revise the calculation. Keep networking, package installation, file browsing, and subprocess expectations outside this deliberately restricted workspace.
Keep exploring the math.
