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.

    As a lerning tool this app sucks. It very dificalt to use there are no hand held muti meters and it deos not let you put the lead lines in as you wish. They just go where evy the program makes the. Very disappointed! !!:-(

    I pay for the full program and get a larger workspace and now you want me to buy the parts included in the update? Your a crook and a con. Now I want my original purchase reimbursed. Stay out of dark allies.

    The developer of this app can use the new components as a Suppository.I have already paid for this & I'm not paying again.

    If the app isn't free (and this one most certainly isn't), don't advertise it like it is. How silly is it that I have to buy all the components separately in a simulator in addition to the components for the circuit? That's precisely why I'm using a simulator, so that I can test them before buying.
