Great but could be better
This is good for high school science students and electrical engineering students (like myself) but some questions that are sections of circuits can't be mapped in here which is a real let down, but closed circuits are great. The app also includes the ability to map gates. Absolutely amazing every physics / engineering student needs this.Show lessSnoopsterz4563
Review avoided
I have been avoiding writing this review along time.
It is the only simulator I have found on iOS.
Unfortunately this program has may serious flaws. So many 6000 character can only scratch the surface. Here is a small sample of the problems.
Interface: landscape panning reduces to default size. Oscilloscope spawns a second instance and neither work.
Stability: gets really flaky if use fro over 2 hours and/or over 50 nets.
Simulation:
All devices are level 1, nor ESR, D, Q etc.
Over unity regulators, micro wats in produces giga watts output.
MOSFET use beta which can only be estimated from gate geometry instead of capacitance/threshold or area/media. Transients real confuse the simulator causing varying simulation stopping errors.
Zener's are limited to 25v and can not be chained in most cases no dark current.
Logic is 1V only.
Support: To-date zero of my bug reports have received a single response, therefore I have no idea if there is any support to comment on.
There many more faults but alas it is the only simulator available for iOS. For the on the move times I can not use LTSpice I am tankful for iCircuit.Show lessWarSim
Useless
Half the components don't work, a simple transistor switch won't work, an scr is non latching, waste of money, very disappointedStevehall604
Outstanding app for circuit design and learning
Excellent tool for designing simple transistor and logic circuits. Would make a very useful teaching/learning aid.
At first, I found the slider controls to set resistor values etc rather tricky to use and a bit over-sensitive; but then I discovered that if you click on the numerical value you can enter a precise setting using the keyboard - hooray! That makes it worth 5 stars for me.
Am finding it very useful for designing bipolar transistor amplifier circuits.Show lessmjcross
Needs Measurement Device Representation in Circuit Diagram
Please include the ability to add an ammeter/voltmeter/ohmmeter/oscilloscope/function generator/etc. in the circuit diagram itself! Even if they're not actively functional (although obviously that would be ideal), I need to represent those features connected with the circuit to show in my lab report! Other than that, I like the app interface in general. Great design, but it doesn't do what I need at present.
PS. Also, please consider adding a resistor color-code scroll wheel utility for setting the value of resistors. (See "ResistorCC" in app store for reference.) This would eliminate the scroll-bar issue (at least for that element) and help bridge the connection between the digital prototype and the physical lab, making it easier to go from the screen to the bread-board! You could also add scroll wheel settings to set the values of other elements as well apart from color-coding, but it doesn't make sense not to for resistors.
Thanks, looking forward to the next update!Show lessBigword123
Really powerful
This is a really powerful app does a lot and has so many hidden features I am no pro at this stuff but I can tell you the pros could use it I mean it does everything and has everything!!!carlowisse
Old but active
Have been designing analog with digital control commercially for 40+ years and now retired. This is the best design and simulation tool I've ever used apart from the high end commercial software with an appropriate price tag. Excellent value for money. Has a few quirks but once you are used to them they are not bothersome. Makes the iPad the best investment since the spec-an!Show lessREM2706
Good but could be better.
Although I have a background in programming software, I could still learn a few things about hardware. I purchased this app to learn.. However, I am having a hard time doing so with ONLY examples. Maybe a description menu of each part could be added? Also, controlling and adding wires is a pain.. They never seem to follow my finger, but tries to take another path for some reason (it's not because that path is shorter from its destination, because I have plenty of examples of when it isn't). Also, a permanent menu should be added to copy, past and delete. It's too hard and time consuming the way it is right now (mainly the deleting part)... Also, perhaps you could add an editing menu to LEDs to change the color? I would like to have other colors besides red.
I'm still new to this app, so maybe my complaints are only because of my lack of experience. I look forward to future updates and my rating will be higher :)Show lessCode Phox
Great for conceptual work
I use iCircuit in my classes to demonstrate more complicated circuits than we have time to build by hand. Just today, one of my students wanted to look at circuit models of neurons. She'd had never used the app before, but she was able to construct an example model she found online in less than 10 minutes and we were able to get a good sense of how the circuit works.
I have found the app invaluable for teaching circuits, though there are limitation. On my iPad 2s that I have in my classroom, the app will crash when you build a circuit that oscillates with a high frequency. While this isn't a full circuit simulator and it has it's limitations, it's a great classroom tool and well worth the price.Show lessPhysTeach1
Keeps improving!!
I got this app when it had mostly just a resistor capacitor inductor op amp and a diode with the standard voltage devices. In the beginning I was sad to see a limited number of parts so I gave it at 4 stars.
Since i had my circuits class, when i bought this app, it's had vast amounts of improvements. I can't say enough of how much I jump with joy every time I see an update for this app. I bought a digital storage oscilloscope for debugging prototype boards. I've confirmed its accuracy with my real circuits and scope after "trusting" it's virtual scope's accuracy for many months of use. That makes me a true believer in this app and hopefully others find it as useful for themselves!Show lessThat one guy who that thing
