# Mechanical Pendulums vs Relativity Simulator

The clearest difference is device support: Relativity Simulator at 2 against Mechanical Pendulums's —. Mechanical Pendulums's advantage is iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
