# iMaster vs CNC Simulation‑Handbook

The clearest difference is in-app purchases: iMaster at none against CNC Simulation‑Handbook's 1. iMaster also leads on iOS requirement (12.0 vs 15.6). On price, ads and device support there is nothing between them.

Both are free to download. CNC Simulation‑Handbook sells 1 in-app purchase, starting at $1.99 per 7 days. iMaster asks for nothing beyond the download.
