Description

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.

Not so good!

Initially this is a basic tool with some interesting abilities. Needs more symbol to be added. After creating a couple of circuits, I left the program. Came back and the circuits were gone, so were the examples, and all the settings were unavailable. This program needs some updating and fixing of the obvious trap doors.

Update. Tried saving to the iCloud and the circuits built lasted longer... Tried to select a circuit out of a folder I created to send to printer and then entire folder was lost along with the examples folder. Went to look on local iPad and not there either.

According to the manual, the use should be able to access the "Trash" folder. Unable to do so with the program loaded on my iPad 9 Pro. As a result of continued problems, I have downgraded my rating to a single star. One of the things I noticed is there have been no updates to the APP for about a year.

Very nice real time simulator

You design your circuit, then hook up a power supply, and you have instant real time simulation. Just double tap on a wire or component, and a menu pops up giving you the option to plot (voltage or current or both) at that wire/component location, keeping it visible all the time, until you undo the option. This is good as a current or volt meter permanently set at those locations.

If you single tap on a wire or component it will highlight, and show both current and voltage at that location, but it will disappear when you tap to unhighlight it.
This feature gives you the option to do quick checks on current and voltage values, at locations without cluttering the schematic.

Now every time you make a change to the circuit, immediately the values of current and voltages update , shown at all locations. This is handy with variable resistors as you can guage current and voltage changes as you adjust the variable resistance.
The entire circuit updates in real time.

Great, until...

I made a few circuits for some practical effects in a show, and as a lighting designer and master electrician it's very helpful to make them on the go, send them off, and have the practical test ready when I get in. However, in sharing a folder out, I lost everything in it on the first try. It was only a few schematics, but I have to now make them again. Trying to load the circuit file into the app didn't work, and none of the schematics I made came up as visible (just blank pages).

So, while its nice to make these on the go, it's a little useless if I can't send them to anyone. I would say this would be well worth $10, if you could share the folders successfully. Otherwise, it's very useless organizationally.

(Also, you can't save anything as a PDF to iCloud Drive, which is just weird).
