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!

galaxy note Not bad please add an on and off switch for simulation just like ios version.

SGS2 Lots of components. But it is very hard to use. The interface gets in the way of itself and the components are hard move around and manipulate. A lot of potential,but it needs some work

Crasher burns App will not run on any tablet I own except the Nexus 7. On all others it crashes as soon as you try to do something with it. Crashes often on the Nexus also. I haven't really been able to do anything with it due to the crashing problem. Vendor does not respond to questions for help.

Great stuff...but Some glitches need attention such as the speaker function which crashes the circuit but its still worth a punt

Has potential N/a

Great but needs improvement I said I was going to wait for a free version but I went ahead and bought it, this app is very good but should work on some of the flaws it has. I'll try and point them out in an email. But overall for a new app this is great! Edit: this app is new, it should atleast have some updates considering the fact that that it has some complaints.

Galaxy S Does not work.... At all.

by A Google User the 10/13/2012

Great Many parts, nice design, I like it a lot more than other circuit sim apps But needs UI tweeks -Include a more efficient way of adding parts -The scope needs to be more smooth at higher frequencies -the timing of pulse voltage (visual) does not coincide with what it does to the counter (see counter ex) -the simulation seems verry fast, and somewhat glitchy -can you make a defaults menu in settings?

by A Google User the 10/6/2012

It's incredible! But there's some bugs.. This apparently is deliciously great, especually! But there's a few bugs. When I change the size of a file, it goes back to the standard size when you add a new element. Also, when I try to use speakers, the file closes and it goes back to the file select screen. Lastly, maybe I'm doing something wrong but using digital gates and subcircuits things get really messy and don't really work. Still figuring out for myself but it might be notable.

Very rough UI Forced full screen (i.e. no system status bar). No time reset. Various other UI faults. Still the best one on Android that I've used. A transmission line element would be nice. CORRECTION: tap one node, then another to add wire. Convenient.
