About PROTO
PROTO (Package Name: com.proto.circuitsimulator) is developed by PROTO and the latest version of PROTO - circuit simulator 1.39.0 was updated on June 13, 2025. PROTO - circuit simulator is in the category of Education. You can check all apps from the developer of PROTO - circuit simulator and find 158 alternative apps to PROTO - circuit simulator on Android. Currently this app is for free. This app can be downloaded on Android 6.0+ on APKFab or Google Play. All APK/XAPK files on APKFab.com are original and 100% safe with fast download.
Are you looking for tools like Multisim, SPICE, LTspice, Proteus, Altium or PhET simulations? That's great! PROTO is an real time electronic circuit simulator which means you are able to setup a circuit with various components and simulate behaviour of the electronic circuit ⚡
During simulation you can check voltages, currents and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time! Our app can greatly help with your Raspberry Pi, Arduino or ESP32 project. You can also use PROTO as logic circuit simulator and perform digital electronic analysis!
