5 Free Circuit Simulator Apps for Android

Here is a list of 5 free circuit simulator apps for Android. Designing and simulating a circuit can be a complicated task but it can be done on an Android device. There are decent apps available on the Play Store covering a wide range of features. I covered 5 such apps that you can use to design basic logic gates to complex electronic circuits.

All these apps offer various electronic components necessary for circuit designed. With those components, you can design the circuit and simulate it. These apps offer AC, DC, Transient circuit analysis, and SPICE simulation. During the simulation, you can check the various reading like voltages, currents, and other variables.

Some of these apps also allow you to use your device’s components in the circuit such as proximity sensor, accelerometer, microphone, charging, etc. During the simulation, the apps take input from the device in real-time. Apart from simulation and analysis, some of these apps can also create circuit schematics that you can print or export to PDF.

My Favourite Circuit Simulator App for Android

I couldn’t pick a favorite from these 5 circuit simulator apps. Because circuit simulation is more about the components and features rather than functionality. All these apps have similar functionality but with different sets of features. Here I listed different types of components and features these apps offer. You can go through the lists and pick an app best suited for your specific needs.
