iCircuit

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.

this app is amazing and I has helped me understand things that I need help on but there’s just one thing that needs to be added and that’s capacitor discharge delay. For example when an LED is connected parallel to a capacitor of any capacity and then when the voltage source is disconnected, the LED will not slowly dim. It doesn’t only affect the dimming of an LED but also rectification and circuits that require a delayed fade to operate properly. I hope that the creator of this app reads this and fixes this problem so more circuits can be made!

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...

I have been using this app on my iPhone and iPad. For one thing you have to make different purchases to use it on different devices. This is unfair. I should able to use the app both on my iPhone or iPad alternatively. They don’t have the option to log in and hence you have to keep purchasing if you change your device. Second, the parts are not working properly. For instance the zener diode will allow the flow of current in both direction for all values of the input voltage. This is completely wrong according to the principles under which zinger diodes should behave. I think you don’t really need to purchase this app unless you want to add your money to ash like me. From what it is, this app is really useless.

In my last review I was very frustrated with how it was not working any more, and I thought it was because they didnt care about this app any more. This is what I wrote, then: “Used to be the best circuit simulator around, even better than the computer versions of electronics workbench. Now it is notworking at all, very poor app. Will not work on updated versions of ipad.” HOWEVER NOW, I APOLOGISE, I was wrong in thinking you didn,t care! There is a lot of time and effort, needed to keep updating your app, to keep up with the changes in oprating systems. Shame on me to acuse you of not caring about your customers. You DO care about keeping your apps up to date, it just takes time and resources to do that. I want to say THANK YOU, to all of you who put forth the tremendous effort to bring this app to high standards again. GOD Bless you all for your time and efforts.
