Good features but hangs frequently

Very nice features, but why does it hang frequently on iphone 14?

Also, why does it assign auto label (like a, b, c) and adding custom label does not remove the original auto label?

Would give a five star with these two problem fixed.

It got frozen

It got frozen when I tried to save the current file. I cannot use apple pencil to draw the wire to connect gates so had to use fingers and due to the terminals are small so it hard to see if the wire get connected or not when the finger covers the terminal.

Having a hard time to pick the correct input or output for wiring

For some reason Whenever I want to wire a gate it only picks the output, even when I try to choose one of the inputs.
It would be helpful if Apple Pencil can be used for wiring.

GREAT APP

it does what it needs to in a great way.

To build an advanced circuit, an ipad helps with the additional scene space and an apple pencil helps with the tiny buttons

it's really good for what it is

question for the developer: there is a "share" option. i finished a cool circuit and i wanted to see how to export it, and the app crashes vey time i click the "share" button... what are the designed export options?

thanks

love the app

Response from developer

Thanks for using the App, The Share option uses the standard iOS Share sheet, which let you pick the app you want to share the design with.. The main two choices is the Mail App, and the Files App... However, I've tested the share option in the app, and it seems to work well. If this issue is still happen, then please send the details to the Support mail address.. and Include the device model name, iOS version, App version, and a screenshot of the error message... thanks

I like!

I find this logic gates app enjoyable and helps with understanding!
However, my old iPhone 6+ gets warm while using it... not sure if this is something that can be fixed?

Fantastic App

This app is fantastic! I use it to demonstrate and “play” with digital logic. Much better than getting out the breadboard an my old TTL chips. Well thought out and friendly interface.

Super good for my learning of logic circuits,but theres a problem

This application is one of the best I have ever found but the problem is, I can’t manage to rotate anyof the logic gates or stuff like that.Developer, if you’re reading this,please add a rotation option for this to be perfect :D

Good

I am a 2nd year electrical engineering student going to third year, this is a really helpful tool to learn about the basics of combinational and sequential logic. One thing though, how does the JK flip-flop in this app supposed to work? It doesn’t seems to have a clock input.

JK Flip-Flop Doesn't work when J=K=1

Drawing wire is too difficult - could have a pencil and draw from any point other than only from the ouput pin!

In addition, there is no clock input - though it has postive/negative clock selection.

One more, can’t wire feedback to self, or can't have multiple wires connected to the same node. Thus can't even make a Linear Feedback Shift Register with D-Flip-Flop!

Thanks for frequent updates. Please fix the uneven scales on timeline.

Good to see improvement and prompt bug fixing. Well done!

Excellent

A great product, convenient, multi platform, with ease of use, well thought out..... Regularly updated.

Better than Ever!

The latest round of improvements for V3.5 have really made this simulator a lot better.

It’s got some nice features like Circuit Append, and Grouping, which make it easier to create your own library of commonly used logic sub-circuits or modules.

The improved Zoom and Pan features make it easier to move around the workspace and see what you want.

It’s surprising how much you can do on your iPhone with this App. Highly recommended. 5⭐️

UPDATE: Great logic simulator, very responsive developer

UPDATE 2: The latest update fixes the remaining issues I had with the app 😄. I would definitely recommend this app to anyone needing a logic simulator on their phone, and the developer is very responsive to fixing any problems you find in the app, and adding any useful suggestions 😀.
One minor UI tweak that would be nice is if the zoom in/out would be centered between your fingers, like it is on most other iOS apps, rather than being centered on the top left corner as it is now. Alternatively being centered on the center of the screen when zooming would be slightly less ideal, but still better than it is now, and likely easier to implement.
It also would help when making complex circuits if when you’re interacting with a particular component, the lines coming out of it were highlighted in a different color, and similarly, when running the circuit, if the lines were highlighted showing if they were on/off, rather than just the dot at either end showing that like it is now. It would also be useful to be able to change the colors of wires after creating them, and easily change the color of all wires going to a particular connection at once.
It also could make it easier to deal with circuits if when dragging a wire to an off-screen part it would automatically scroll when pulling it to the edge of the screen, or let you scroll manually with another finger.

UPDATED REVIEW: The new update fixes most of the problems I originally noted, making this app much more friendly to use 😃. It’s great that the developer listens to and acts on user feedback. However, on the iPhone X many of the top bar’s buttons are mostly blocked by the phone’s “notch”, resulting in users needing to tap randomly in that area and memorize the position of the different functions. Once this bug is fixed I will definitely use this app often.
Overall this is a great update, with just this one pain point for some devices.

Another nice-to-have but not essential feature would be the ability to open multiple circuits at once and connect them together/combine them, which would allow modular design that could be connected when complete. A good example of its use is with the multiplexer and demultiplexer example circuits, which could be combined together to better demonstrate their function.

ORIGINAL REVIEW: This app works, but is not very user friendly. It would be much more useable if you could zoom in an out, as another review mentioned, you can barely fit any useful logic in a single screen before needing to scroll. It would also be useful to have an alternate method to long tapping, for example 3D Touch on iPhone 6s and newer. Also just decreasing the delay of the the long tap required might help quite a bit.

With these things fixed and a few other small things (e.g. a typo, the Help menu is labeled "Halp"). Also the developer should really be more kind to users, rather than accusing them of "not having common sense", instead realize that perhaps the app could communicate functionality better.

This app also freezes occasionally, requiring a force quit, losing my progress, which obviously needs fixing.

The ability to save and load projects is also critical in this sort of app.

Overall the app works, but is likely not user friendly enough for widespread regular use, but with a few minor improvements as mentioned above it could be incredibly useful! I hope the developer takes my advice in this review, this app has the potential to be great!

Thanks for rating, I just released an update, which includes most of your recommendations. plus a lot more. Thanks & Regards.

Terrible

Poorly coded, bad visuals, horrid controls.

It's the quality of a free app, but for $4.
