Awesome just needs a few fixesThis app is great. It simulates pretty much everything. There are some missing ics but way more than any other sim I’ve used. The arduino simulator is decent. There are some bugs with certain functions like “sizeof”. Hopefully this gets updated. All in all worth the sticker price. The iOS app is way better than the pc version..HueylouieVersion: 1.11.1

I heart this appI am no electrician, but I love to tinker. I know enough to be “the one in the family/group” to go to. I last used this app to help me create a simple LED driver for an array of grow lamps of different frequency and intensity with potentiometers (I love to over do my projects with options). Some plants like full sun, some don’t. Some respond better to more ultraviolet, some other frequencies. Now, go online and find a decent set of grow lamps with the same features and watch your wallet disappear. Always DIY when you can. This app can help with such things!.Who Cares about nicknames9Version: 1.12.2

Fantastic design prototyping and simulating on the goIf you are into rapid prototyping your circuits and on the go, this app is for you. I’ve saved countless hours not only designing but easily simulating my circuits. Don’t understand people that say this app isn’t professional grade. It’s clearly meant for the enthusiast and pro who is mobile and needs to rapidly test out and prove that their designs will work. Also a great teaching tool. The biggest complaint I and others have had is that the developer is way too busy and that the updates have literally taken years to push out. But the January 2023 release is chock full of new components and goodies and long overdue. There’s simply nothing else that comes close for iOS. Well done and 5 stars. Thank you!!.Deeee1234Version: 1.12

Mostly GreatSometimes circuits with dependent sources don’t converge properly. Like they’ll shoot off to infinite voltage or something when they shouldn’t. Sometimes this can be fixed by toggling the circuit on and off. Sometimes you just have to be lucky..Suchir KaviVersion: 1.11.2

I’ve never seen nothing like it.I’m a radio amateur and been designing my own equipment for almost 20 years and this takes most of the work out of getting the exact circuit values and designing a transceiver circuit by circuit. Well worth the money. Hats off to the developer, you are a genius..Bryanjj078Version: 1.11.2

Beats expensive alternatives in many waysI’ve gone through a number of simulators and this seems to hit the sweet spot between ease of use and the number of features. It’s nice to get an immediate response in the simulator to circuit changes. Keep developing this great app and continue to add more components!.LincolnparkdcVersion: 1.11.2

Fun to use, works well with Apple PencilThis is way more fun than the simulators like spice than I learned on I was pleasantly surprised to find out that it works very well with Pencil on iPad, even being able to write in component values can't pla wait to play with the arduino sim. No varistor though?.WolftagVersion: 1.11.2

Much better. UI for placement is hard to use sometimes.UI is sometimes hard to use ... pushbuttons are hard to orient and i cant figure out how to get diagonal wires. They just happen sometimes..NzcVersion: 1.11.2

Decent but not perfectI use this on an iPad mini with an Apple Pencil. The core functionality is there, but the scope is a bit buggy, sometimes requiring me to restart the app. I hope it gets fixed because for $13 app I’d hope for more consistent features..RbArbyRbVersion: 1.11.2

Great way to [re]learn electronicsIf I’d had this app when I took electronics in high school, I’d probably be an EE now instead of relearning what I only barely grasped back in the day..The Life of BryanVersion: 1.11.2

Amazing!This app is great for learning how circuits work!.BigZaphodVersion: 1.12.2

Seems excellent, Few things missingFirst off, fantastic app. The features work well, and overall i think the UI is handled very well. The app has all the basic parts that are needed to do most of what I would want to do. I recommend this app overall. That being said, there’s some limitations i’ve noticed from playing with the app (hopefully eventually to be addressed). One: no built in non-ideal op-amps. At the very least having control/modeling some basic things like slew rate adjustments and output capabilities without using a subcircuit model would be great. Another thing missing is vacuum tubes, along with triacs and diacs. People have requested it but the author has said looking into it since 2014, without much update, at the very least copying the models from the source of Falstad’s site would work if that’s the holdup. TVS devices (both single and bidirectional) and MOVs would be nice too. Along with spark gaps. SCRs do exist already though, and fairly powerful dependent sources and subcircuit support means it’s likely possible to manually implement common models of these components somewhat, but it’s not an ideal path. A huge feature would be supporting some sort of bode plot setup, even just something basic like a series of transient analysis passes across a frequency range would go a long way if i could observe phase and gain plots. DC analysis at different varying operating conditions would be another super useful feature and probably easy to add. Finally noise analysis. The most practical and I suspect the least easy to jump on but it would have a lot of value for making the app cover all the bases of basic circuit analysis needs. The settings dialog and using the file browser interface as the home screen was a little confusing but was really not too hard to figure out and the documentation is very straightforward. The Arduino integration is very neat and makes this app one of the more useful circuit simulation references I’ve been able to design with..PhosyyVersion: 1.11.2

FantasticAmazed that this is all on iPad..Blah345Version: 1.11.2

Great AppFive Stars.EvoaaaVersion: 1.11.2

An app that keeps me “amped”This is a very fun educational and actually quite an effective utilitarian tool. I am an electrician with two apprentices under my wing and like using this tool to draw out how our builds are supposed to work. The oscilloscope is a great learning resource. I even admit I like using it to experiment whether I can simplify one of my own circuit designs. I’m an electrician which means I’m a “take charge” kind of guy and were relied upon to design and build circuitry to a customers needs at an economical cost. I would love to see more AC applications such as three way, four way and double pole double throw switching along with single and three phase motor(until then I just build one representing the inducers and use ohms law to calculate amp draw and output). Circuit breaker representation, and LED drivers and fluorescent balasts would be a plus too. I really enjoy the app and only have minor problems involving bugs. Other than that it is an overall “shockingly” fun app that keeps me “amped” and the price didn’t “hertz” at all and can’t wait to see “watt” you have in store for the future..Dewey Cheatem&HoweVersion: 1.10

Love It!Absolutely love this.F2959Version: 1.13

Needs Measurement Device Representation in Circuit DiagramPlease 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!.Bigword123Version: 1.4

A few changes would make this app perfect...Bought this app years ago and started using it again when some of my more “professional” spice programs failed to work with some of my circuit designs. I use Multisim, TINA, QUCS, LTSpice and every circuit and iCircuit handles my designs better than ALL of them! Obviously it doesn’t handle real components like some of the other programs, but for prototyping it holds it’s own with any of them (some of these programs are professional tools costing hundreds to thousands of dollars). There are things that could be improved...adding a trigger mode or two other than roll mode for a start would help. Also adding a frequency sweeping option to the sources would make better use of the frequency domain measurement mode. Update: what I’d to see added to iCircuit is a programmer’s interface to allow me to customize or create models for unsupported components, like varacters and specialized transistors....Creynol5Version: 1.10

Pretty great app, probably blows away the competition, could still use some basic improvementsThis 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..Krb686Version: 1.4.7

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 :).Code PhoxVersion: 1.4

Great app. Easy to use. Functional. Mostly complete.I'm an Electrical Engineering student and lab assistant. For my job as a lab assistant, this app is great for demonstrations to the new students. It is also great for hobbyist applications. I really appreciate the simplicity of the user interface. It's really easy to use and I love the included oscilloscope and DMM. Way easier to use than several programs that I've tried previously. The biggest downside that this program has is that you can't create your own symbols. For most of my applications I require the ability to take a full sheet, turn it into a symbol and include that symbol in another schematic. This app is entirely devoid of that option, insofar as I am aware. That is the one feature I wish this app had that it is lacking. Other than that, it's a wonderfully well made app..OnemoorefamilyVersion: 1.4.7

Excellent learning toolI am enjoying the usability of this ap. Not so complicated as the spice model as far as flipping back and forth through simulation data. Instead the the simulation takes place as you build the circuit, so you can see how the different components interact. The use of the meter and the scope is genius. The only nocks against this app are the limited component library and the fact that you can't move the meter scope leads from an a-b configuration to say a and c in an a,b,c,d circuit. You can do a-b, b-c, c-d, and d-a, but to go from two points that aren't right next to each other, is a no go. This however does not seem to limit the app as much as you would think as you can display all the readings on every part of the circuit at the same time. So you can see instantly the pertinent numbers..SlniesVersion: 1.4.7

Great for conceptual workI 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..PhysTeach1Version: 1.4

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)..OffenhofferVersion: 1.8.4

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!.That one guy who that thingVersion: 1.4

ICircuit AppThis app is fantastic, but unfortunately falls short of what it could be, in my opinion. Many have requested, and continue to request, the inclusion of a vacuum tube module for this App. From my understanding, that request has been ongoing for the better part of almost a decade. Again, this is only one user’s opinion, but this will never be a well rounded App until at least this feature is included, and with the same professional approach applied to the existing App..Rivendell ResearchVersion: 1.11.2

This is a really good app... take a little time to learn how to use itI am not an electrician or electrical engineer (are they the same? 🤷🏼‍♂️). I picked this up cuz it says for beginners and hobbyists too. There is a learning curve but that’s more to get used to how the app was intended to be used. This company clearly puts A LOT of work into this app and they are clearly listening to the feedback they have been provided and it shows. There are a bunch of symbols to build your circuits. Yes, you probably will find some components have been left out, but from the sounds of things, people are getting by. Folks are building some crazy things out there! The interface is really intuitive so they aren’t lying to you when they say you’ll be working on it in minutes. I found that the spots where I was stuck just ended up turning into another learning experience. I would definitely suggest trying iCircuit out. There is a free version, so you can find out if you have the patience or time for it. Lastly: for anyone who really didn’t enjoy the app, temper your review a bit. If you really think they missed the mark with iCircuit, BUILD YOUR OWN APP! Show us how it should be done. Okay, rant over. Go iCircuit!.SLIcore JimVersion: 1.11.2

Amazing resource for EE undergradAbsolutely fantastic resource for testing simple circuits. interface is a little jankey at times, and the power consumption is abysmal. But a very useful app for getting through my undergrad courses..TinhornNinjaVersion: 1.11.2

This app is better than meI’m a very novice electronics diy’er. My profession is installing automatic industrial door and gate systems. I use this to design and test real life applications for custom control scenarios (current project is a custom controller for a secured parking lot for an app based short term car rental company to automatically close the door after a renter has finished renting the car and exiting the lot or they finished with their rental and returned the car and have safely exited the lot on foot). This app has helped me learn a lot about electronics and made me better at my career as well as saved me a lot of time by being able to design and debug and test my circuits so I can build them in real life. It has way more components and features than I know how to use fully and works very well for my needs. Highly recommended!.DMKyle1Version: 1.12.1

GreatDon't let some of the bad reviews turn you off. This app is great. Some people expect way too much.

Only thing I want is more source options(3 phase, 120/240 single phase..)..LittleRockRockVersion: 1.2

Review avoidedI 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..WarSimVersion: 1.4.7

Love it!This is a great app. Love it. The simulation is fantastic and you can build some complex circuits in no time and test out some ideas. I come from the digital world so I really value the analog part. Great for a hobbyist. I just took some circuit about building a heater controller and in 15 minutes, i could see everything real time. Just fantastic. It is missing very few components (diac and triac but you can make those easily with diodes and scrs in anti-parallel). Can’t say how much I love this app! I can start on my phone and go to the iPad Pro and back... Awesome job!!!.Max_thedogVersion: 1.8.4

Great, but majors bugsI love this app. Fantastic simulation. But there are several major errors that makes using it hard. The biggest error is that if you try to share a folder, the folder gets whipped out. I lost 5 days of work and it wasn't backed up. I had subcircuits, shift registers working, and many other things.

Last UpdateIcircuit was an excellent product. The last update made it unusable. The issue is auto wiring. I always set making circuits so I control when I want to wire the components not a programmers assumption. Now regardless of when I turn on wiring or not, it auto wires, messing up the circuit. It is a waste of time, and very frustrating when I want to rotate a component but instead I start wiring, then have to delete it, then try again, with hit or miss results. Prior version was excellent, this version ruined the program..Daimon 6Version: 1.8.1

ICircuit Negative Reviews

Sounded fun, but it’s a nightmare.I really wanted to play around with a simulation, but it fights you every step of the way. The settings are barebones, the interface, drawing and deleting fight you EVERY step of the way, you can’t rotate stuff and scaling things is only in one direction, for a barebones list of components they just direct you to the wiki instead of detailing the twenty or so in-app for QoL. This would be a fun $2-5 toy to play around making basic starter boards, but I’d be laughed out of an office if I handed the spaghetti mess that comes out of this to a professional. Eh, at least it was an entertaining thirty minutes for an extreme premium. Oh yeah, and hats off to the inept technical genius who made it so pressing “undo” keeps undoing thirty minutes of stuff. This UI is a technical dumpster fire. I’m going to RTFM and give it one last shot later, but that won’t fix the lack of intuitive and intelligent design..AppleKingOfTerribleUXVersion: 1.11.2

What happened?This app used to be awesome, I haven’t used it for a while and I just downloaded it again and it’s super buggy. It doesn’t matter how much you zoom in before you touch something or select something. It always thinks you’re trying to select or touch something else and then it messes the whole circuit up. Undo is unreliable. It just feels weird now it used to work really well..Diss ApointeDDVersion: 1.13

WORST CIRCUIT SIMULATOR EVERSo many bugs, I have never seen so many bugs in an app in my life. DONT BUY!! I rather spend $50 for an app that works.

InaccurateInaccurate therefore not very useful. I tried something simple like shorting a capacitor and it was inaccurate..Roger ArmstrongVersion: 1.11.2

Unusable due to UI issueI purchased this app to help with an electrical engineering circuit design class. Upon downloading and installing, I was initially impressed with the design simplicity, and unique style that this app has. I attempted to model some simple circuits, but then I found a fatal flaw. Once an element is placed and saved, and unable to undo, it is nearly impossible to delete. This is largely do to the incredibly touchy nature of the UI on iPad. The UI demands that in order to delete a circuit element, you must select it, and momentarily press the element in order for the option menu. The menu then lets you delete it. However getting this menu is nearly impossible, because if your finger moves even the most fractional amount, the interface does not recognize the press. I've found that I would try to press 10+ times on an element just to get the menu, and this is simply unnacceptable. Until they patch this problem, this app is unpractical for any application. Once they patch the issue, I will happily recant my review..SeanumesesVersion: 1.8.2

Limited functionality of the ArduinoCoding the Arduino is very limited.DataLineMan.comVersion: 1.11.2

Not a lot of optionJust the basic switches and relays available are lacking. Makes designing even simple stuff impossible..Takagari2Version: 1.14.2

Heats Up Phone and Drain Battery Fast!It heats up my phone and it drains my battery so fast. Please fix this bug and make it more efficient. Also please add a current signal for AC, there’s only AC voltage but no AC current..Gello73Version: 1.14

App houndWow , does this app ever need a lot of work it took me three hours to draw a simple bridge rectifer . Most of the time was spent trying to move components and deleting unwanted wires. What a disaster. It only crashed about 35 times in that three hours. I'm using a 64 GB iPod 4 and my 220 other apps are working just fine. Ten dollars is definately too much to pay for this app . Wait a few months before buying this app. , I'm sure it will come down in price, because right now this app is pretty much useless for any practical purpose. I don't know if I'll ever open this app again because I can do any diagram on paper with a pencil a thousand times faster than I could ever do with this app. This app is all glitter and hype and a lot of wishful thinking. Don't buy this App !! ( until it works like they promise ) I love the idea of this App but it doesn't work!.BubblybobVersion: 0

Waste of moneyCan’t even export circuit drawing pictures, for this quality this app should we free.KmaximoffVersion: 1.10

Ne fonctionne plusMettre beaucoup d’énergie pour préparer mes cours et faire des démos. Maintenant l’application se ferme, gelé ou tout disparaît 😩.BowclapVersion: 1.9.3

Crashes and not workingComplete garbage, totally waste of money, crashes on iOS 10.Justin.,?!',Version: 1.8.4

Crashes on openingNeeds updating..Bubble_master_XVersion: 1.8.4

Crashes on iOS10This app is mostly very good and did crash often, but now it just crashes upon launch. Please update ! Im using iPad Air 2 128Gb so not a hardware issue..TouchtheworldVersion: 1.8.4

Poor touch interfaceThis app would be amazing if the touch interface worked. Zooming in and out and moving components around us a nightmare on my laptop and even worse on my iPhone. It's slightly improved when I use my mouse but still pretty crappy..Apple Blade.Version: 1.8.2

BunkDo not purchase. Couldnt get an AC to DC power supply to work. Pulsing from zero with a large cap after the bridge?!... Garbage..$Vagabond$Version: 1.7.1

Miss some componentThere is no fuse, no battery, parallel DC source not work correctly ( it give an error ) need to ad some more IC chip..PyrotechVersion: 1.4.7

Great app but crashes oftenOn iPhone 4S, if you change something in the circuit then open the scope, the app usually crashes. Otherwise it's fantastic..Magneto_57r1<710|\|Version: 1.4.7
