# Pixel Sphere 3D vs Knotle

The clearest difference is ads: Knotle at none against Pixel Sphere 3D's shown. Pixel Sphere 3D's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Pixel Sphere 3D sells 1 one-off in-app purchase and Knotle sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
