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 SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).

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.

    This is a great app and at 10 bucks I really had to think twice about getting it. If I knew you were going to charge more on top of it I would have never have bought it in the first place. I was recommending this app to my friends but not now.

    This is a good app. I love the ability to build and simulate circuits, especially on a portable device. HOWEVER, I hate that the developers had to go down the in-app purchase road. I hoped that after paying full price that I would get the upgrades for free, or at least in a bundle deal. And now they even charge for AC analysis? At 1$ for each part, and $9.99 for the full app, I won't be upgrading

    I have paid for the full version and you want us to pay a dollar for each additional component that's stupid. New components should come with paid version app update for free.

    New features shouldn't cost more

    I paid full price for this app. Why try to weasel a few extra bucks off paying customers in the name of selling components?

    Bought the paid version when this app first came out. Now they want more money for different components and circuits. This is ridiculous! Paid version should get these updates free of charge!

    Nothing new to add... Keep charging more, that's the way..
