# 3D Printing vs AI Training Simulator

The clearest difference is update cadence: AI Training Simulator at every 2 days against 3D Printing's every 2 weeks. 3D Printing's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 3D Printing sells 2 in-app purchases, starting at $19.99 per month and AI Training Simulator sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

3D Printing ships an update every 2 weeks, AI Training Simulator every 2 days. Both last shipped on October 24, 2026.
