# Gravity 6D vs Huygens3D

The clearest difference is ads: Gravity 6D at none against Huygens3D's shown. Gravity 6D also leads on price ($1.99 vs $5.99) and iOS requirement (12.0 vs 17.0). On in-app purchases and device support there is nothing between them.

Gravity 6D costs $1.99 and Huygens3D $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
