Play continuously or step through a model when a particular moment matters.
See how a mathematical model behaves, not only where it ends.
Callie Pro combines time-driven graphing, Complex 2D and 3D visualization, scientific constants, symbolic math, matrices, statistics, and numerical scripts for physics exploration on iPad.
The workspace is designed for inspecting change, structure, and relationships across formulas, paths, surfaces, exact values, and sampled data.

Turn supported equations into systems you can play and inspect.
Temporal Mode adds controlled playback to supported functions, parametric paths, polar graphs, complex paths, and 3D surfaces. Pause, step, change speed, loop, and inspect live readouts as time changes.
Compare supported time-driven graph fields against the same temporal position.
Use Trace, slices, contours, and readouts to examine the model rather than relying on animation alone.
Inspect complex functions as paths and height surfaces.
Complex graphing can display magnitude, argument, real part, or imaginary part over the complex plane. This makes roots, poles, branch behavior, singularities, and transformations easier to compare visually.
- Rotate and zoom Complex 3D surfaces.
- Use contours and slices to expose structure.
- Trace exact positions on supported complex-plane graphs.
Keep reference values, symbolic work, and numerical checks together.
Catalog supplies organized scientific constants, CAS handles exact structure, and the local Python workspace supports small numerical experiments without leaving the calculator session.
Keep exploring the math.
