# CompositesAI vs Relativity Simulator

The clearest difference is ads: Relativity Simulator at none against CompositesAI's shown. CompositesAI's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

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