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
* 37 7400 series digital parts
* 7-segment display and driver
No matter your profession, we're sure you'll be amazed by iCircuit!
ATTENTION Because iCircuit is a very CPU intensive application, it is recommended that you only use it on newer generation hardware including: iPhone 3GS, iPhone 4, and iPads. However, it will still function on the older hardware.
What's New in Version 1.4.7
* Fixes a bug preventing the simulator from working correctly on iOS 4.3 devices
Pretty great app, probably blows away the competition, could still use some basic improvements
This app has most of the basic passive and active components you might need, plus some more complex parts like digital gates, op amp, and some larger packages. The simulation aspect also seems pretty accurate, I've built a working joule thief so it does inductive coupling in transformers accurately.
Some of my cons:
1 - Needs a delete button. I want to be able to quickly click on a part and then click the delete button, not hover for a second and wait for the bar to pop up, and sometimes it doesn't register.
2 - Needs discrete scope probes as parts you can add to the circuit. Maybe even voltmeter and ammeter parts that can be added. Like some SPICE sims have, it's more intuitive. And also the support for the probe itself to display whatever it's measuring right there on the circuit, maybe in a text label, so I don't have to switch back and forth from circuit to scope.
3 - The scrolling through parts could be better implemented. Sometimes it gets hung up because it doesn't know if I'm trying to scroll or drag a part. Maybe a separate bar to scroll with.
4 - More parts, of course, and also part folders with some kind of organization.
Overall though, it's a great app, the highest quality circuit sim you'll find. If you need to simulate, fork out the 10 bucks. It's worth it.
As a professional electronics engineer, I've always found engineering apps to be seriously lacking... until this one. It is so nice to be able to explore ideas away from the desk: sketch it out, simulate it and get trustworthy results. Also, the performance is quite good on my 1st generation iPad.
The things I'd really like to see in future versions are:
1. Add triggering capability to the oscilloscope. I have to constantly stop the simulation in order to examine a waveform in detail.
2. Add markers to the oscilloscope.
3. When a wire is deleted, the entire length of wire is removed, not just a section of it.
4. Add the ability to select and move, or delete multiple items. Theres an edit mode where wires can be drawn, maybe add a delete mode where tapping an item deletes it. Also a move mode where items can be repositioned easily.
In conclusion, this is a great app that has truly added value to my professional life. This app is well written and quite worth the price.
Uh, guys... ?
I just paid $10 for an app that gives a 'loop with no resistance' error on the most basic of circuits... one where there is very DEFINITELY resistance: place two DC sources on separate current loops through a single resistance (the visual- sources left and right, resistance in between, polarity of the sources such that each current loop would pass same direction through resistor... like looking at an electric mixer running... ).
My guess is that this is a function of lack of internal resistance in a battery source? Even considering this, the above scenario should still work given identical DC sources. Still, this is an amateur glitch in an otherwise excellent program.
Also, drawing neat circuits is nearly impossible. The wires seem to refuse to travel in a straight line, making instead odd unnecessary right-angle detours around... well... around NOTHING. Frustrating! And to correct this, you have to manipulate the size of the components and then are left to delete all of the leftover wire bits. And if the wire is one 'square' long, you have to first extend the size of the wire just to be able to select it for deletion. SLOPPY!
So close to being a great app... I'm gonna contact these guys. Will update if I get a response. Or if I don't...
