Logic Simulator Pro

Great app. Just a suggestion, it would be wonderful if you can let us save a circuit and then put it inside a box which we can then use in other circuits. It would remove my need for other things such as more than two inputs being ANDed or ORed or etc...

This is so helpful... An amzing app... Helped me alot in my DLD course.... But righr now m facing a problem while designing counter using jk flip flops i need to connect setter of one flip flop to pre of other one this app doesnt alloa that. Could u helpmr

Several things about this app are great - the UI is simple and easy to navigate, and the selection of components is reasonably complete without being overly large. Unfortunately, in addition to the function issues other users talked about, it's often very hard to see how wires are connected since they can't be manually drawn and often overlap, and the mandatory timed full-screen ads that pop up every time you try to open a file are pretty unforgivable. Won't be keeping this one.

This works good.But in case of synchronous counter and sometimes in asynchronous counter it gives wrong output.I designed a 3 bit ring counter but output was not correct.So I advice the maker to pay attention in that part.Except that problem, that is a good and useful app.

Circuit points do not connect. Circuits forgotten. Components disappear. No way to make copies as backups. D-flip-flops did not work as expected or as spec'd by TI. Circuitry interface not intuitive, important for apps with skeletal help.

When I got the app I quickly got the hang of using it, and just as quickly learned more about circuits, but I feel it needs more to it. To begin with where is the battery for a more realistic circuit? Also I would love to see more inputs/outputs to the app, such as a motion, light, and motion sensor for inputs and a camera, motor, and other possible outputs. What I feel would blow the app out the water is a simulation side to the app where you can see the before mentioned inputs/outputs in action. Once again thank you for a great app and I hope you will continue upgrading it

If I zoom out or in my phone restarts, or the game crashes every time . May there be an option on the GUI for zooming, good game with potential

for jk flip flop if j=1,k=1,; Q=Q'.... but in your app, for same input, Q=1 for all time. note that, the circuit was triggered properly

I can construct circuits but, the bulb glows whenever connected to any ofthe components excpet low constant, I connected a bulb to a empty t flip flop shows bunl glowing , same with the LED display , if this app is nkt meant for receiving output , will you pleas explain for what reason I'm supposed to use this?

Like they said before, small boxes that have only I/O but you don't know what happens inside.

Can't include one saved circuit inside another; can't label things; issues with evaluation behavior means B = A XOR (NOT NOT NOT NOT A) is monostable

I think this app should have a feature that allows the user to copy and paste logic gates. Also, I suggest that logic gates can allow atleast 3 or 4 inputs for connection. Lastly, please add Integrated circuits. Thank you!

First, the answer to the D flop flop problem. It seems that the PRE and CLR inputs have been inverted somehow, adding a high source seems to fix the problem. OK, now suggestions. Fix that. Also, more component variety, and a more user-friendly interface to obtain bits. Clicking through four menus to get to a clock is absurd. Copy-paste, perhaps? Encapsulation would be good. Look into some sort of compression that turns finished models into Unity functions. Finally, add tooltips for components.

This is the best digital circuit simulator that I have ever seen! The user interface is simple, there is a rich set of components to use, and the simulation quality is great! Thanks!

It is a very good app everything is fantastic but unfortunately you can't make complicated circuits for example gates doesn't have more than two inputs I hope the developer make the app better good luck

Some of the clocks don't sync and little things like that my largest problem is the clock speed is off the 2hz is more than double then the 1hz

Great app, very stable and simple. Here's some feature suggestions -add intergrated circuits from other creations. - remove gradients - add selections and copy and paste - allow an option to unselected a circle on a component (stop it from being green) - if you have already saved, stop it from asking to save when you exit something. Thanks for making such a stable app.

This app is amazing. I absolutely love it. It would be nice though for a copy paste system. Adding 18 buttons isn't easy. Lol

I want add input logic gates.but can't add input logic gate.I want use decoder and add more input.please edit more for app.

But add input wire. Such as I cannot make 3-input logic gate here.

Please add simple addressable memory array. It would be fine to have some configurable ROM to use with circuits, 4-pin MUXes and LED indicator. Also please replace lamp by LED since it is more suitable for the world of semiconductors and digital logic.

Please add an option to minimise view of previously made circuits and use them further in more complex circuit building.

Its great! All it need is a way to access the component menu faster (like swiping) and a undo/redo option at the top. ;)

A few minor additions and I would easily give this app a 5 star rating. For example, logic gates with 3 or 4 inputs. I know I can create those with combinations, but multiple inputs would really help.

Love this app! Super useful for testing circuits before building them. I would love to be able to label inputs and write comments. As others have suggested, compressing and saving built circuits for would be a very useful feature.

would be a great addition. It would be nice to be able to build a full adder, for example, and use it in more complex circuits. That said, I use this app a lot. Good job.

I have just started playing with logic gates tonight and already fell in love with them due to this app <3

Dont require a lab to test the circuits can simulate any circuit includin complex ones :-)

I want to be able to turn stuff around and connect random stuff together and make it stay in one place please add this

would be a great addition. It would be nice to be able to build a full adder, for example, and use it in more complex circuits. That said, I use this app a lot. Good job.

It has a lot of potential, but a few glaring issues. First of all, the ability to encapsulate complex circuits into small black boxes to be used in more complex circuits would be a boon. Secondly, some of the components (namely, flip-flops) aren't working as they should. If these were fixed, I'd give it 5stars.

Something I'd like to see, which others also asked for, is the ability to export circuits to custom chips and reuse them in other builds. Also, gridsnap please

The only request I have is the ability to move wires. Sometimes the wires cover up some of the gates, inputs, etc. It would be nice if we could organize them manually.

I wish I could discover this app again! Here is what can make this app better: Copy/cut/paste, saving circuits for use in other circuits, and more components.

The UI could be a smoother and easier, as far as manipulating the components, but it's pretty self-explanatory and works like it should as far as I can tell. I just started an EE program and am studying logic gates now, and I imagine this will come in handy.

Very good for new and innovative circuits absolutely love it!

One of the best progs I've ever installed. Like a minecraft for people with iq more than 1. Very-very nice. I would just advice u to develop the idea. It's awesome, but functionality may be increased. I would be glad to see new features in newer versions. Also I would advice u to add some kind of grid mod to align the components somehow. Thank you.

Great app but there are some issues with the D flip flop.

Auto-rotate is kind of annoying and the memory cell is reversed , saves off as on and vice versa.
