# Relativistic vs RelativityTheory

The clearest difference is price: Relativistic at Free against RelativityTheory's $0.99. Relativistic also leads on iOS requirement (9.0 vs 14.4). On ads, in-app purchases and device support there is nothing between them.

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