# Earth's Core vs Vector3D

The clearest difference is in-app purchases: Earth's Core at none against Vector3D's 1. Earth's Core also leads on iOS requirement (12.0 vs 16.6). On price, ads and device support there is nothing between them.

Both are free to download. Vector3D sells 1 one-off in-app purchase. Earth's Core asks for nothing beyond the download.
