EveryCircuit 2.27 [free]

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.
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.
