I like the app especially the simulation part, went as far as purchasing the full version to continue using it but after awhile it went away and went back to trial mode, it recognizes I purchased it but fails to update when I go to restore it.
I tried purchasing the unlimited version, but luckily I was told that I have already purchased this before and can just unlock the full version. Great! So I did that, and when trying to run a circuit comprised of 2 voltage sources, a transistor, 2 resistors, and an LED I was informed this was a “large circuit” and that I would have to purchase the unlimited version…which I already had transferred my previous license. It seems the app currently does not recognize that you have an active subscription and will limit you to the pre-made circuits. I’ll change my rating once the dev team updates the issue.
I recently loaded this app but could never find a button to push to buy the app from within the app. I sent two requests to there site and got “don’t care about the customer” style of service!!! The best app is not worth this and you probably feel the same way.
I love this app but I need more ICs. still love this app! :)
I’ve been trying to figure out why the capacitor simulation never runs correctly. I tried several different self made circuits that would blink a light when the capacitor is charged, but if never worked. I assumed it was my error. Today I found a LED flasher circuit that someone else made in the community, and I opened it. IT WORKED! … and then stopped. I didn’t change anything about it. I just paused the simulation, then started it again. Nothing I did made it work again. After several tests, I *think* the simulation breaks when running capacitor charges. At least, I tried four different RC circuits and none of them behaved as they would in real life. And several other kinds I tried wouldn’t pass any current at all. So. I think it’s the simulation. I really loved the simplicity of this app, but it’s making me feel like I’m going crazy. I hope that if this is actually broken there will be a fix soon.
I bought the full version and it worked just fine, however as I moved onto simulating larger circuits it asked me to purchase the app once again as if I haven’t
The voltage flow on the ipad vs the web are different directions
Needs more building space ..
The pieces cap is annoying use of some parts makes it cap out faster meaning I can eliminate one on some alowing simulations but others require several to be deleted before anything can be simulated
I took a chance for the $13 because I have not seen anything for iOS that can do basic SPICE simulations, and I can't stay tied to the desk to run MicroCap 12 (now free and still awesome). This app won't let you perform complex circuit simulations of complicated circuits (abut that's what MicroCap is for). The op-amps have no voltage rail pins for example. There is no q-point, or distortion metering. If you need a full fledged simulator, get MicroCap for free and use your laptop. But - this app is amazing if you are trying to understand networks involving reactive components. Especially when it involves multiple loops or nodes. You can also use the op-amps in normal configurations - amps, integrators, etc... The in-place AC and DC meters are pretty cool. I found a use for it immediately for a work project that involved stacks of capacitors, fed with different sizes of a common AC input signal (pulse generator). The app worked perfectly and allowed me to see something MicroCap can't - the effect of charge pushing on the bottom plate of a cap modulating the signal fed to the top, in real (sim) time, yet the overall total signal maintains the shape of a single cap charge/discharge. Brilliant - so easy when you can see it right there. I wish it had some very basic features - copy/paste, multiple component selection, and a real-time frequency response (spectrum analyzer) would be nice. It also has some quirks with starting/stopping sims. I actually like the spinner control for setting component values.
