About this app

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 circuit 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.

Voltsim is an electronic circuit simulator app with in-build logic circuit simulator and digital circuit simulator.

The examples provided with the app cover the basic functionality of all components.

Some app use-cases:
learn electronics
electronics circuit simulator
circuit simulator arduino (upcoming)
electric circuit simulator

You can report an issue or make component request at https://github.com/VoltSim/VoltSim/issues or just email us :)

Feature highlights:
* Material, intuitive user interface

Legimitely one of the best out there. Sleek, powerful, a lot of fun to use, and a really commendable pricing structure. Can do a whole lot for free, and can get lifetime full featured for $10 or pick just the modules you want. Really wish more apps would take note.

Free circuit simulator not hidden behind a paywall, so useful for simple circuits. Other components are hidden behind a paywall.

My Dream at 3AM was to make a sandbox app of electrical circuits where you can make and plan circuits before actually building IRL to see if they will work or not , and apparently as I was searching for a Voltmeter app I stumbled across this app which LITTERALY fulfilled my needs , TYSM DEVELOPERS👍♥️♥️♥️♥️🎉
