This app is only available on the App Store for iOS devices.
iCircuit is the premier iPad and iPhone 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
• 38 7400 series digital parts
• 7-segment display and driver
• Antenna with simulated AM and FM signals
You can also create sub circuits to introduce new elements and componentize your designs.
No matter your skill set, you'll be playing with circuits in no time with iCircuit.

* New 3D Touch preview of circuits
* New dark theme
Massive money saver
It's not perfect (there will always be something extra) and CAD on a tablet with a pudgy finger is always going to be less than ideal.
However, as experienced hobbyist (and less than great designer), this has saved me countless hours of experimental work in testing my ideas. It's also saved me a bundle in components since I can make sure my ideas work before I even need to get the breadboard out.
I'm not smart enough to see how some circuits work on paper but this allows me to see them work in real time (and tinker) without the need to get out of bed!
More to come?
This has the makings of a great App. I wanted to test circuit values for a long tailed pair and it was able to help me design a viable transistor circuit. Some improvements I would like to see. It would be great if you could leave the scope on one component or circuit point whilst changing the value of a different component. Same with the meter. Also it would be good if you could select the meter for DC Levels for biassing while a signal is passing. Also a way to easily measure gain between two points in a circuit. I hope these ideas can be incorporated into an update. Thanks for a good App.
I do not normally write reviews, but felt compelled to as I have read some bads reviews for this App. I am a chartered electronics / systems engineer and I use iCircuit for interactive presentations. It is no substitute for Pspice, but for my modelling of stray currents and earthing/ bonding it is absolutely fantastic. I would happily have paid ten times the amount for this App. For those of you that have concerns I have validated the results with a fully licensed copy of Pspice and the numbers are the same; but Pspice does not allow you to run scenarios based on peoples 'real time' questions.
