iCircuit review
A cross-platform circuit design app for exploring analog and digital behavior in real time.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
iCircuit is a circuit design and simulation app for students, hobbyists, and engineers who want to explore how analog and digital circuits behave. Its editor lets users place, connect, and configure components while simulation runs in real time. That makes it suited to learning, circuit exploration, and prototyping rather than broader electrical-design workflows centered on panel layouts.
The simulation tools give the app useful depth for circuit work: users can probe voltage, current, and power with a multimeter, track multiple signals on an oscilloscope, and inspect circuits with Bode plots and FFT analysis. A component library includes analog and digital parts such as logic gates and microcontrollers. Subcircuits and custom elements support reusable modules, while audio simulation can model speakers, buzzers, and microphones. These capabilities make iCircuit a fit for people who want interactive feedback while changing a circuit, rather than only a drawing environment.
Versions are available for Windows, macOS, iOS, and Android, so the product spans desktop and mobile use. The listed purchase model is paid, with an optional in-app purchase note; the App Store listing describes a one-time purchase. Its scope is narrower than a full electrical-design suite: panel design and MCAD integration are not included. Choose iCircuit for portable circuit simulation and exploratory learning; look elsewhere if panel design or mechanical CAD integration is central to your workflow. Support is listed through email.
