Circuit simulator apps for Android: PROTO, VoltSim, EveryCircuit and more
Android has several good circuit simulators. They fall into two groups: electronics simulators, which compute voltages and currents through real components and show them on meters and oscilloscopes, and logic simulators, which deal only in 0s and 1s. PROTO, VoltSim and EveryCircuit are in the first group and include logic gates too; Logic Circuit Simulator Pro is in the second. All the facts below come from each app's own store listing or website. Pick by what you want to learn: electronics with real components, or the logic inside a computer.
How to choose
For analog circuits with an oscilloscope, start with PROTO or VoltSim, which are free to install with in-app purchases. For animated circuits that also run in a browser and on iPhone, EveryCircuit, whose free version limits your own circuits to 5 components. For a big parts bin of ready-made logic (gates, flip-flops, PLA, ROM, multiplexers) on Android, Logic Circuit Simulator Pro. (digiwleea is an independent project, not affiliated with any of these apps.)
Where digiwleea fits
digiwleea is not an Android app: it runs in the browser, so it works on Android phones and tablets, iPhones and computers alike, with nothing to install. It is a digital logic lab that starts one level lower than the apps above: you build NOT and NAND from NMOS and PMOS transistors, then adders, latches, registers, RAM and an 8-bit CPU that runs a stored program, through a 40+ level course where every part is checked against its truth table, with an AI tutor (Wleea). It has no analog parts; for voltages and waveforms, use one of the apps above.
The apps side by side
| Kind | Runs on | Price | |
|---|---|---|---|
| PROTO | Analog and digital, four-channel oscilloscope | Android | Free; in-app purchases |
| VoltSim | Analog and digital, oscilloscope and multimeter | Android | Free; ads and in-app purchases |
| EveryCircuit | Analog and digital, animated | Web, Android, iOS | Free up to 5 components; $5 a month or $15 once |
| Logic Circuit Simulator Pro | Digital logic, large parts bin | Android | Free; ads and in-app purchases |
| digiwleea | Digital logic from transistors, guided course | Any browser, incl. Android | Free lab and Act I; Premium course |
For simulators that run in a desktop browser, see online circuit simulators compared.
No sign-up is needed to start: open the lab and place your first transistor, or read the free theory course. The account (and the AI tutor) are optional.

See for yourself: build a logic gate from transistors in the simulator, then follow the path from sand to an 8-bit CPU.

What is the best circuit simulator for Android?
It depends on the job. PROTO and VoltSim simulate analog and digital circuits with oscilloscopes; EveryCircuit adds an animated view and also runs on the web and iOS; Logic Circuit Simulator Pro focuses on digital logic parts.
Is there a free circuit simulator for Android?
PROTO, VoltSim and Logic Circuit Simulator Pro are free to install with in-app purchases, and EveryCircuit has a free version limited to 5 components. digiwleea's free lab runs in the Android browser.
Can I learn digital logic on my phone?
Yes. Logic Circuit Simulator Pro gives you ready-made logic parts, and digiwleea runs in the phone's browser and has you build the gates yourself, from transistors to a CPU.
