## iCircuit Description
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), 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  
• 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  

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.

## iCircuit Reviews in United States

### *---- "What happened?"
This app used to be awesome, I haven’t used it for a while and I just downloaded it again and it’s super buggy. It doesn’t matter how much you zoom in before you touch something or select something. It always thinks you’re trying to select or touch something else and then it messes the whole circuit up. Undo is unreliable. It just feels weird now it used to work really well.
-- Diss ApointeDD, 2024-12-26

### **--- "Unstable"
Was enjoying it until today when opening work file and it was corrupted and no possible recovery.  Hours of work and Arduino debugging lost! This does not seem to be for real work. Just an expensive distraction. Find another alternative.
-- Ngnear1111, 2024-08-04

### ***** "Love It!"
Absolutely love this
-- F2959, 2024-07-12

### ***** "Fantastic"
Used to build and simulate a battery cell simulator which I built on a breadboard and later PCB.
-- pgibbons5, 2024-06-13

### *---- "WORST CIRCUIT SIMULATOR EVER"
So many bugs, I have never seen so many bugs in an app in my life. DONT BUY!! I rather spend $50 for an app that works. I love that you guys are giving people a simulator for electronics but you guys have to understand it is very frustrating to do something when there’s so many things goes wrong and then you have no undo button to undo anything that the app has cause you to delete.
-- china is a alien, 2024-05-08

### ***** "Huge new update"
This is one of the most under-appreciated apps around. This app is SO GOOD and does SO MUCH.
-- pblair, 2024-04-01

### *---- "They are thieves? Don’t buy this App !!!"
This app does nothing. They charge you a bunch of money and give you nothing and then want to charge you more money to get more features, what did I pay $16 for?
-- opelone, 2024-01-20

### *---- "Don’t buy"
Everything dost work holy moly lm317 dont work
-- other1989, 2023-12-08

### ***** "Amazing!"
This app is great for learning how circuits work!
-- BigZaphod, 2023-11-19

### ***** "I heart this app"
I am no electrician, but I love to tinker. I know enough to be “the one in the family/group” to go to.

I last used this app to help me create a simple LED driver for an array of grow lamps of different frequency and intensity with potentiometers (I love to over do my projects with options). Some plants like full sun, some don’t. Some respond better to more ultraviolet, some other frequencies.

Now, go online and find a decent set of grow lamps with the same features and watch your wallet disappear. Always DIY when you can. This app can help with such things!
