What iCircuit is
iCircuit is an electronic circuit simulator and designer for students, hobbyists, and engineers. It supports schematic capture and advanced electrical simulation for analog and digital circuits, with real-time analysis that runs continuously as designs change. Users add elements, connect them, and set component properties; the maker describes more than 30 elements, including sources, motors, LEDs, ADCs and DACs, logic gates, flip-flops, 7400-series parts, and an antenna with simulated AM and FM signals. A built-in multimeter probes voltage and current, while an oscilloscope tracks multiple signals over time. Users can create subcircuits to introduce new elements and organize designs. The app runs on Android, iOS, macOS, and Windows, including iPhone, iPad, and Android phones and tablets. Speakers, microphones, and buzzers are unavailable on Windows. Circuit files can be emailed or saved in CIR format. The core app costs $12.99, paid once. Optional Pro plans cost $1.99 a month or $14.99 a year and add extra components.
