# Linear Algebra vs Vector3D

The clearest difference is in-app purchases: Linear Algebra at none against Vector3D's 1. Vector3D's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Vector3D sells 1 one-off in-app purchase. Linear Algebra asks for nothing beyond the download.
