The CNC milling machine simulator is a multimedia application designed to provide a basic introduction to beginner mechanical engineering professionals with the principles of programming operations for milling parts using a standard (ISO) G-code. The main task of the application is syntactic analysis (parsing) of the code of control programs in order to build a graphical model of cutting tool trajectories in three-dimensional space. The main functions of the application: editing the code of the control programs of the milling machine, operations with files of control programs, setting the geometric parameters of the cutting tool, continuous/step-by-step execution of blocks of control programs, three-dimensional visualization of tool movements in the working space of the machine, simplified visualization of the machined surface of the part, calculation of processing modes, a quick reference guide to using G-code. The main limitations of the application are: low accuracy of cutting surface modeling, the impossibility of using polygonal geometry as a workpiece, a simplified model of machine tooling elements.

Verdict
The clearest difference is price: Pythagoras Calculator at Free against CNC VMC Simulator's $6.99. Pythagoras Calculator also leads on rating (4.6 vs 2.9) and review sentiment (83% vs 48%). CNC VMC Simulator's advantage is in-app purchases (none vs 8). On ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Pythagoras Calculator is free to download; CNC VMC Simulator costs $6.99 up front. Pythagoras Calculator sells 8 one-off in-app purchases. CNC VMC Simulator asks for nothing beyond the download.
Pythagoras Calculator holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: Pythagoras Calculator has 242 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 83% of Pythagoras Calculator's written reviews are positive against 48% of CNC VMC Simulator's.
Pythagoras Calculator ships an update every 3 weeks, CNC VMC Simulator every 3 months. Both last shipped on October 18, 2026.
