iCircuit

What iCircuit does

iCircuit is a realtime electronic circuit simulator and designer developed and operated by Krueger Systems, Inc., a privately held U.S. corporation founded in 2010. The product is built around a proprietary always-on simulation engine that continuously analyzes analog and digital circuits as users modify them, distinguishing it from traditional SPICE-based CAD tools that require discrete simulation runs. iCircuit supports more than 30 circuit elements including resistors, MOSFETs, logic gates, 38 7400-series digital parts, 7-segment displays, ADCs/DACs, signal generators, antennas, speakers, microphones, and buzzers, with additional support for PIC microcontrollers (via a custom Circuit ASM assembler) and Arduino-family boards (Uno, Mega, Nano, ESP32, ESP8266). Users can create custom ICs with HDL components using Verilog or VHDL and build modular designs with subcircuits.

The business model is a one-time-purchase consumer app distributed exclusively through four major app store marketplaces: Apple App Store (iOS/iPad), Mac App Store (macOS), Google Play (Android), and Microsoft Store (Windows). iCircuit employs a product-led growth strategy targeting students as its primary segment, with hobbyists and professional engineers as secondary audiences. Distribution relies on app store discovery and a community-driven Circuit Gallery that enables user-generated circuit sharing. There is no disclosed pricing on the company website, no external funding history, no enterprise sales motion, and no named institutional customers — consistent with a founder-owned, independently operated software product focused on the consumer and education markets globally.

Core offering

iCircuit is a realtime electronic circuit simulator and designer sold as a paid application across iOS, macOS, Android, and Windows platforms. Its proprietary always-on simulation engine continuously analyzes analog and digital circuits while users build and modify them, providing instant feedback through a virtual multimeter and built-in oscilloscope. The product supports over 30 circuit elements including resistors, MOSFETs, logic gates, 7400 series digital parts, Arduino boards, and PIC microcontrollers with an integrated assembler.

Product overview

iCircuit is a single unified product — a realtime electronic circuit simulator and designer. It is available across multiple platforms including iOS (iPhone/iPad), macOS, Windows (Microsoft Store), and Android. The product features an advanced simulation engine that handles both analog and digital circuits with always-on analysis, a built-in multimeter for probing voltages and currents, and an oscilloscope for tracking signals over time. Supported elements include signal generators, voltage/current sources, logic gates (AND, OR, NAND, NOR, XOR), JK and D flip-flops, 7400 series digital parts, 7-segment displays, and microcontroller support including Arduino boards and PIC microcontrollers. Users can create subcircuits to introduce custom elements and componentize designs.

Direct peers

• EveryCircuit: Web and mobile realtime circuit simulator with a focus on animated, interactive circuit visualization. Most direct competitor to iCircuit given shared realtime simulation philosophy and cross-platform consumer focus.
• CircuitLab: Browser-based circuit schematic editor and simulator with both free and paid tiers. Comparable target market of students, hobbyists, and professional engineers needing quick circuit validation.
• Falstad Circuit Simulator: Free browser-based realtime circuit simulator widely used in education. Comparable to iCircuit in offering immediate visual feedback and broad component coverage, with the key difference of being free and web-only.
• Proteus: Mixed-mode circuit simulator with integrated PCB design and microcontroller simulation. Comparable to iCircuit in providing schematic capture and analog/digital simulation, though primarily a professional Windows desktop tool.
• LTspice: Free SPICE-based circuit simulator from Analog Devices widely used by students and engineers. Directly comparable as an analog/digital circuit simulation tool, though it uses traditional batch simulation rather than iCircuit's realtime approach.
• EasyEDA: Web-based EDA tool with schematic capture, SPICE simulation, and PCB design, integrated with PCB manufacturing services. Comparable as a multi-platform circuit design and simulation tool targeting students, hobbyists, and professionals.
• Tinkercad Circuits: Autodesk's free educational circuit simulator with integrated Arduino simulation. Competes directly for the student/STEM education segment with circuit building and embedded code editing.

Broad incumbents

• OrCAD: Industry-standard EDA suite from Cadence for schematic capture, simulation, and PCB design. Comparable in the circuit design category but operates at the professional engineering tier with enterprise sales.
• Multisim: Professional circuit design and SPICE simulation platform from National Instruments. Overlaps with iCircuit in analog/digital simulation but targets universities and professional engineers as part of a broader NI test and measurement portfolio.
• Altium Designer: Professional PCB and electronic design platform used widely by engineers. Compares to iCircuit in the schematic and simulation category, but anchored to professional PCB design workflows rather than education/hobbyist use.
