iCircuit
iCircuit is a Mac circuit design and simulation app for building, testing, and learning analog and digital electronics in real time.
What is iCircuit?
iCircuit is a native Mac circuit design and simulation app for creating, testing, and studying electronic circuits. It is aimed at students, hobbyists, and engineers who want to explore how analog and digital designs behave without setting up physical hardware first. The app combines a schematic editor with live simulation, so circuits remain active while you place components, change values, and observe results. It supports common electronics workflows such as building circuit diagrams, experimenting with component settings, viewing signal behavior, and sharing circuit files or exports. iCircuit also includes a large component library and support for programmable devices such as Arduino-related workflows, which makes it useful for both learning and prototyping. Krueger Systems publishes iCircuit for macOS through the Mac App Store.
Key features
- Build and edit analog and digital circuit schematics on a live canvas
- Simulate circuits in real time while changing components and values
- Add components from a built-in library of electronic parts and logic elements
- Inspect voltages, current flow, and signal behavior as the circuit runs
- Configure element properties and circuit settings for experiments and study
- Share or export circuit work for printing, images, PDF output, or reuse in other iCircuit versions

Safety overview
Status: Safe
iCircuit is legitimate circuit-simulation software for macOS. Its normal behavior is to save your circuit projects and settings, and any network use is generally tied to app features such as support, sharing, or accessing related online content. It is not the kind of app that typically needs unusually broad system permissions for its core purpose. As with most creative or technical apps, keep copies of important circuit files if you rely on them for school or project work.
Recommendation: Keep iCircuit if you use it for electronics design, simulation, or learning. Remove it if you no longer need it, but export or back up any circuit projects you want to keep first because uninstalling the app may leave you without easy access to those files.
