CNC Lathe Simulator is a software simulator of a numerical control lathe is an educational methodological development intended for basic familiarization of novice machine building specialists with the principles of programming parts turning operations using standard G-code (ISO). The three-dimensional simulation model is based on a lathe with an inclined bed, equipped with a CNC system, a twelve-position turret head, a three-jaw chuck, a tailstock, a system for supplying lubricating and cooling liquid, and other units. The material is processed along two controlled axes. Field of application of the software product: educational process using computer technology: laboratory lessons of students in computer classes, distance learning, demonstration support of lecture material in the group of areas of training and specialties: «Metallurgy, Engineering and Material Processing». The main functions of the application: editing the code of control programs of a lathe, operations with control program files, setting up geometric parameters of a cutting tool, continuous/step-by-step execution of control program blocks, three-dimensional visualization of tool movements in the machine’s workspace, simplified visualization of the workpiece surface, calculation of processing modes, a brief reference guide on using G-code. The graphics component of the software uses the OpenGL 2.0 component base. The graphical user interface of the program is implemented in English. Limitations of the Light version: it is impossible to change the length of the workpiece, only two positions of the turret head are available.

Verdict
The clearest difference is rating: Geometry Calculator lite at 4.5 against CNC Lathe Simulator Lite's 3.7. Geometry Calculator lite also leads on ratings volume (79 vs 11). CNC Lathe Simulator Lite's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, 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
Both are free to download. Geometry Calculator lite sells 1 one-off in-app purchase. CNC Lathe Simulator Lite asks for nothing beyond the download.
Geometry Calculator lite holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Geometry Calculator lite has 79 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 59% of CNC Lathe Simulator Lite's written reviews are positive against 42% of Geometry Calculator lite's, so the app with the better star average is not the one people write more warmly about.
CNC Lathe Simulator Lite ships an update every 3 weeks, Geometry Calculator lite every 5 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
