# archive vs Vector3D

The clearest difference is in-app purchases: archive at none against Vector3D's 1. Vector3D's advantage is ads (none vs shown) and iOS requirement (16.6 vs 26.0). On price and device support there is nothing between them.

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