iCircuit

What iCircuit is

iCircuit is an electronic circuit simulator and designer for students, hobbyists, and engineers. It handles analog and digital circuits with real-time, always-on analysis. Users add components, connect them, and set their properties; the maker lists 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. Subcircuits let users create new elements and organize designs into components. The app supports schematic capture, advanced electrical simulation, and standards libraries, but not panel design or MCAD integration. It runs on Android, iOS, macOS, and Windows. Speakers, microphones, and buzzers are unavailable on Windows. Circuit files can be shared by email or saved in CIR format for other iCircuit versions. The core app costs $12.99, paid once. Optional Pro plans add extra components for $1.99 a month or $14.99 a year.
