Spatial Vis vs CNC VMC Simulator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Spatial Vis
This app trains students in engineering and science to improve their freehand sketching of 2D and 3D views. Mastering these skills enhances technical communication and spatial visualization, which can lead to better academic performance. It offers interactive lessons and automatic grading for assignments.
- Freehand sketching of 2D and 3D views
- Orthographic projections lessons
- 3D object rotations
- Flat pattern sketching
- Automatic sketch grading
- Gamified learning with hints

Spatial Vis is a training tool for engineering, pre-engineering, and other science and technology students. The app teaches freehand sketching of 2D and 3D views, which is an important skill for technical communication and improving one's ability to visualize shapes in 3D. These skills have been shown to increase GPAs and graduation rates in STEM. Spatial Vis has 10 unique lessons that include orthographic projections, rotations of 3D objects, and flat patterns. Students complete assignments by sketching their solution and submitting their sketch to be automatically graded. Students have access to hints if they get stuck, but Spatial Vis is gamified to encourage students to try on their own before using the help features. Spatial Vis is designed for students enrolled in a course at a participating institution. Instructors and students not at participating institutions may work on assignments and review the course material through the Not For Course Credit mode.
CNC VMC Simulator
This app simulates CNC milling machine operations, allowing users to program and visualize tool paths in 3D. It helps beginners understand G-code programming for mechanical engineering.
- G-code programming editor
- 3D tool path visualization
- Control program execution
- Geometric tool parameter settings
- Machined surface visualization
- G-code reference guide
Read full descriptionHide full description
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: Spatial Vis at Free against CNC VMC Simulator's $6.99. Spatial Vis also leads on rating (3.4 vs 2.9) and update cadence (every 5 days vs every 3 months). CNC VMC Simulator's advantage is review sentiment (48% vs 27%). On ratings volume, ads, in-app purchases and device support 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
Spatial Vis is free to download; CNC VMC Simulator costs $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Spatial Vis holds the better App Store score, 3.4 against 2.9. Both are backed by a comparable volume of ratings — 18 and 9 respectively. Written reviews complicate that: 27% of Spatial Vis's written reviews are positive against 48% of CNC VMC Simulator's, so the app with the better star average is not the one people write more warmly about.
Spatial Vis ships an update every 5 days, CNC VMC Simulator every 3 months. The most recent releases landed on September 8, 2026 and September 23, 2026 respectively.
