When installed the app runs, but appears to be missing pieces. It opens to what appears to be a blank windows (maybe a document), with no instructions and no obvious ways to do anything. There are some tabs that seem to direct to additional features, which ask you to buy something, however I don’t think it works (and purchasing something doesn’t seem to enable the software to work).

Keeps crashing when I try to start a new breadboard.

I’ve been using this app for 18 months now, and it has been a really big help for me. I’d use it to simulate circuit ideas before actually building them, and I’d learn about electronics on it on the go. Now, I’m working on a relatively complex PCB design, and I need to experiment for a bit with a few concepts before i could move on. First… in the chip library, I didn’t come over any comparators. Either I’m blind, or they’re not there. It would be nice if they were there. Two, if there was an in app basic tutorial for creating custom chips using spice, that would be great as well. Thirdly, a basic electronics handbook that had basic circuits and their calculations would be phenomenal. Lastly, as many people have asked before, LEDs with switches will be great as well! I understand it’s hard to develop something like that, but just asking. Otherwise. I love this!

I am a student currently studying lasers and optics, this app has been helpful when I cannot get to a computer to get a feel for circuits. Currently I need to build a circuit using LED's and am unable to find any in the app.

I love the app, it’s just there is no output besides maybe the oscilloscope. Maybe adding something like leds or buttons even would be really cool. Until then, I can’t give it a good review.

As far as I can tell the app is not functioning as I cannot place components and after adding 7 or 8 scopes I crash out.

Will not work on IPhone. Will not allow me to access components. Must be a bug.

Can’t add any components on ipad version. Completely unusable. Also, once the free trial is over, it has so much red text warning you of features that are disabled.. would have been less distressing if missing features advised as part of upgrade in positive wording, not error message like text.

I installed the app from the App Store when I opened it, I was prompted to create a new document, ok, fine. Opens a blank window with the document name at the top, and… nothing. No tools, no menu, can’t type anything, no help to even get started. I’d call it trash, but even trash once had purpose.

Every time I would try and use the oscilloscope and simulate the app would instantly break and close out. That same file wouldn’t be openable for a few minutes.
