The Best Desmos Alternative
Desmos is the best free graphing calculator on the web. But it graphs functions; it doesn't simulate dynamical systems, fluids, circuits, orbits, or PDEs. PolySim covers the graphing basics and adds 390+ time-stepping, physics-grade simulations.
Why teams switch from Desmos
- No dynamical simulation
- No physical solvers
- Graphing only

Use Desmos to graph a function; use PolySim to simulate a system that evolves in time.
