# Magnetism vs Dirac equation

The clearest difference is price: Dirac equation at Free against Magnetism's $0.99. Magnetism's advantage is iOS requirement (12.0 vs 17). On ads, in-app purchases and device support there is nothing between them.

Dirac equation is free to download; Magnetism costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
