About this app

iCircuit is a fun and educational app for designing and experimenting with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.

You use it as you would any CAD program: you add elements, connect them together, and set their properties.

But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports. Instead, you just play with the circuit as you normally would, with the power on!

There are over 30 elements you can use to build your circuits. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates.

The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a touch interface to control the total time displayed and stacked and unstacked modes to easily compare signals.

Supported elements include:

* Signal generators, Voltage sources, Current sources, and Dependent sources
* Resistors, Capacitors, and Inductors
* Manual SPST/SPDT Switches, Push buttons, and Relays
* Diodes, BJ Transistors, and MOSFETs
* Speakers, Microphones, Buzzers, DC Motors, and LEDs
* ADCs, and DACs
* Logic gates: AND, OR, NAND, NOR, XOR
* JK and D Flip-flops
* 37 7400 series digital parts
* 7-segment display and driver

No matter your profession, we're sure you'll be amazed by iCircuit!

I use this app a lot, extremely helpful in designing circuits, only downside is changing values, for example, when changing the color of an LED ( obviously not that important but it should be simple) it can't be done. I can change values, back out of the device and the values change back.. Please fix this problem, or if I'm doing something wrong let me know. Besides that, awesome app.

This app is a great tool. But on my new model android tablet I always have trouble naming a component and manually typing in a new value on a component. I can tap on the area where the value goes in many, many times and it still won't bring up the cursor for me to type a component name or value. It can get very frustrating at times. My iPhone, no problems. Please fix this or if there is a fix already, please advise. Cheers.
