# Open3D vs GCodeReader CNC

The clearest difference is ads: GCodeReader CNC at none against Open3D's shown. Open3D's advantage is iOS requirement (15.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
