EveryCircuit

EveryCircuit is an interactive circuit simulator that lets you build any circuit, tap play, 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 an analog knob, and the circuit responds to your actions in real time. You can even generate an arbitrary input signal with your finger!

Under the hood, EveryCircuit packs a custom-built simulation engine optimized for interactive mobile use, serious numerical methods, and realistic device models. Ohm's law, Kirchhoff's laws, nonlinear semiconductor device equations, and all the good stuff is there. A growing library of components gives you freedom to design any analog or digital circuit from a simple voltage divider to transistor-level masterpiece.

The schematic editor features automatic wire routing and a 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 PCB enthusiasts, and ham radio hobbyists.

EveryCircuit is free to download and use. There is an option to purchase the full version that allows you to build and simulate large circuits, save unlimited circuits, store them on cloud, and sync between devices. It is available via a one-time in-app purchase for $14.99. The app requires permission to access your account for authentication in the EveryCircuit community.
