About this app

All joking aside, this time you will understand how electronic circuits work.

"I stumbled upon some serious gold" - GeekBeat.tv
"This app takes design to a whole new level of interactivity" - Design News

Build any circuit, tap play button, and watch dynamic voltage, current, and charge animations. This gives you insight into circuit operation like no equation does. While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time. You can even generate an arbitrary input signal with your finger!

That's interactivity and innovation you can't find in best circuit simulation tools for PC.

EveryCircuit is not just an eye candy. Under the hood it packs custom-built simulation engine optimized for interactive mobile use, serious numerical methods, and realistic device models. In short, Ohm's law, Kirchhoff's current and voltage laws, nonlinear semiconductor device equations, and all the good stuff is there.

Growing library of components gives you freedom to design any analog or digital circuit from a simple voltage divider to transistor-level masterpiece.

Schematic editor features automatic wire routing, and minimalistic user interface. No nonsense, less tapping, more productivity.

Simplicity, innovation, and power, combined with mobility, make EveryCircuit a must-have companion for high school science and physics students, electrical engineering college students, breadboard and printed circuit board (PCB) enthusiasts, and ham radio hobbyists.

Create an account to unlock the full functionality for a limited time. The full version will employ all of your imagination, and all the screen area of your tablet. Join EveryCircuit cloud community to store your circuits on cloud, access them from any of your devices, explore public community circuits and share your own designs. The app requires a permission to access your account for authentication in EveryCircuit community.

Fantastic, useful and educational, this application simply sets the standard for circuit simulators. I wish it had transformers with 3+ windings, though... and capacitive transformers. I think if it could vary it's simulation granularity based on how much the signal(s) in the circuit are changing, it would would help increase accuracy significantly. To achieve the same effect now, I need to slow the simulation by orders of magnitude.

On my previous apple devices, I used iCircuit. Compared to iCircuit, Everycircuit is smoother in processing, allows you to see more (oscilloscope and component configuration do not take up the whole screen), is better for experimentation, and has an online community feature. Great app if you want to do anything with electronics.

I really enjoy this app. But I'm finding a lot of issues that are blocking my progress. Motors do not work correctly under controller situations. Transistors don't behave correctly. Neither do potentiometers. Transformers are just a dead circuit. And when developing with a 555 timer changing the simulation speed changes the frequency reading which makes it pretty much impossible to know the real world outcome of the circuit I'm developing. For $15 I hoped to see this app have updates.
