creynol5's Review of IcircuitReviewed on 12/29/18 1:28 PM
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.

This was a really good app but from one day, it crashes whenever I open it on iPad Pro, iPad Air and my iPhone 8+ Please fix that I am really sad about that

I am not an electrical engineer by any means but a know enough to get around. I enjoy using this app to make circuits & test before building them. I do keep running into issues of not having some what I thought were common components such as a LM317 voltage regulator or being able to drag a bridge rectifier into the circuit w/o having to use 4 separate diodes. I have a simple circuit I'm designing right now that needs a LM317 but can't finish it w/o this component in iCircuit. An annoyance is the selecting of components or to delete them can be frustrating at times but may just be a price of convenience of having a good app like this on an iPad. Thanks, -Kevin

Moving components around results in crazy wiring that takes lots of effort to clean up, often in a loop somewhere stopping the simulator. It also sometimes ceases to be able to delete things as the context options don't show up until you restart it. It also has problems for complex components, like a 555 timer, where by default it hides the ground, as it seems to crash if you connect the ground pin to ground. Lastly, many basic components are hard limited to certain ranges, for example the diode. To represent a component that is not in the system, I need arbitrary voltage control on the diode. But maxing out at 25 limits you and it crashes if you chain diodes. As others mention, it lacks some basic compound components too, like a full bridge rectifier. Don't expect to prototype anything more than basic concepts with this.

This app is cumbersome and tedious to use. I’m frustrated after 2 hours of trying to make a VERY simple circuit diagram.

Need more components.

Please fix it for new version of iOS!

I'm an EE and have used enterprise-level circuit simulators that are NOT this good. Many of the problems people are highlighting in their negative reviews are due to lack of ability to use the app. I've used it for thousands of hours of moderately complex mixed signal simulation and it works quite well. I really really hope the author keeps updating. 👍🏼

I am trying to design a circuit that involves connecting LEDs. The LEDs that I have have a fwd voltage of 3V and current of 20mA. The problem with this app is that it does not allow you to adjust the value of the current for the LED, it is set to 1A. Also, how do you power up the arduino?

Simply crashing now, you need to update to support new iOS
