iCircuit is the premier iPhone and iPad app for designing, simulating, and learning analog and digital electronics. Its advanced simulation engine provides real-time, always-on analysis so your circuits stay powered and live, just like working with real components. Use it like a CAD tool: add components, wire them up, and set their properties. But iCircuit is unlike typical CAD apps because it is always simulating. You do not stop to take a measurement or spend time configuring reports. Instead, you just play with the circuit as you normally would, with the power on. Build circuits with over 300 components, from simple resistors and LEDs to programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32), Raspberry Pi Pico boards running real MicroPython and CircuitPython, PIC microcontrollers, and 60 4000/7400-series digital ICs (more available with Pro). Connect elements, adjust values, and instantly see the results. BUILT-IN TEST EQUIPMENT • Multimeter: Probe any point to read voltage, current, and power • Oscilloscope: Track multiple signals with touch-controlled time scale, stacked/unstacked views, FFT analysis, and Bode plots • Gauges: Visualize voltages, currents, and frequencies directly in your circuit • Signal generators and configurable sources EXTENSIVE COMPONENT LIBRARY • Raspberry Pi Pico and Pico 2 running genuine MicroPython and CircuitPython firmware • Programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32) • Programmable PIC microcontrollers (assembly and HEX files, more available with Pro) • Power: Voltage regulators (78xx, LM317), sources, dependent sources, power jacks, and simulated antennas • Analog: Resistors, capacitors, inductors, diodes, BJTs, MOSFETs, thermistors, triodes, and tetrodes • Digital: Logic gates (AND, OR, NAND, NOR, XOR), JK and D flip-flops, and 60 4000/7400-series ICs (180+ available with Pro) • ADCs and DACs • Sensors and displays: LEDs, 7-segment, NeoPixels, matrix displays, thermistors • Electromechanical: Motors, servos, SPST/SPDT and DPST/DPDT switches, push buttons, relays, and speakers SPICE, VERILOG, AND VHDL Import vendor SPICE models and subcircuits and use them as components. Write Verilog or VHDL in the HDL element and wire it to the rest of your circuit. CREATE CUSTOM ELEMENTS Build sub-circuits and custom elements to componentize your designs and create reusable modules. Share your custom elements with others via the iCircuit Gallery. AUDIO SIMULATION Hear your circuits. Speakers, buzzers, and microphones produce real audio output. Perfect for students learning electronics, hobbyists prototyping projects, and engineers validating designs, all without burning out a single component. ABOUT ICIRCUIT PRO (OPTIONAL) iCircuit is a complete app with a one-time purchase. iCircuit Pro is optional and adds extra components (including more PICs and a larger 4000/7400 IC library) and helps fund ongoing development. Pro is not required for core simulation or everyday circuit design. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

iCircuit and C++ Compiler(Pro) both sit at 3.8 stars, but that hides the real split: 61% of iCircuit's written reviews are positive against 0% of C++ Compiler(Pro)'s. iCircuit also leads on update cadence (every 4 weeks vs every 6 months) and ratings volume (140 vs 2). C++ Compiler(Pro)'s advantage is price ($2.99 vs $12.99) and in-app purchases (none vs 2). On rating, ads, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

iCircuit costs $12.99 and C++ Compiler(Pro) $2.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. C++ Compiler(Pro) asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

C++ Compiler(Pro) holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: iCircuit has 140 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of iCircuit's written reviews are positive against 0% of C++ Compiler(Pro)'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iCircuit ships an update every 4 weeks, C++ Compiler(Pro) every 6 months. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
