"This app takes design to a whole new level of interactivity" – Design News

Design any circuit, tap the play button, and watch dynamic animations of voltage, current, and charge in real time. Gain insights into circuit behavior like no equation ever could. While the simulation runs, tweak parameters using intuitive analog knobs and see your circuit respond instantly. You can even draw custom input signals with your finger—yes, it's that interactive.

This level of real-time responsiveness sets EveryCircuit apart from even the most advanced PC-based simulation tools.

EveryCircuit isn’t just about visuals—it’s powered by a custom-built simulation engine designed specifically for mobile interactivity. It uses robust numerical methods and accurate semiconductor device models. That means Ohm’s Law, Kirchhoff’s Current and Voltage Laws, nonlinear device equations, and all essential circuit theory are fully implemented under the hood.

With an ever-expanding library of components, you can create anything from basic analog circuits like voltage dividers to complex digital designs at the transistor level.

The schematic editor includes automatic wire routing and a clean, minimal interface—less clutter, fewer taps, more efficiency.

Simplicity meets innovation and power, all in a mobile package. Whether you're a high school student studying physics, a college-level electrical engineering student, a DIY breadboard builder, a PCB designer, or a ham radio enthusiast, EveryCircuit is an essential tool for learning, designing, and experimenting.

EveryCircuit is free to download and use. For advanced features, unlock the full version with a one-time in-app purchase of $14.99.
