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.

VoltSim is a realtime electronic circuit simulator like Multisim, SPICE, LTspice, Altium or Proto for circuit design with a better user experience. VoltSim is a complete circuit app in which you can design circuits with various components and simulate an electric or digital circuit. During simulation you can check voltage, current and many other variables. Check signals on multichannel oscilloscope or multimeter and tune your circuit in real time! You can also use VoltSim as logic circuit simulator and perform digital electronic analysis! This app will help you visualize how the voltage varies across the circuit and how current flows through it. T&C: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is price: Circuit Simulator at Free against CNC VMC Simulator's $6.99. Circuit Simulator also leads on rating (4.7 vs 2.9) and review sentiment (73% 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.
