# 车工计算器 vs CNC Simulation‑Handbook

The clearest difference is iOS requirement: 车工计算器 at 13.0 against CNC Simulation‑Handbook's 15.6. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 车工计算器 sells 3 one-off in-app purchases and CNC Simulation‑Handbook sells 1 in-app purchase, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

车工计算器 ships an update every 5 weeks, CNC Simulation‑Handbook every 3 weeks. The most recent releases landed on September 29, 2026 and October 20, 2026 respectively.
