Digital Circuit Simulator Lite Reviews

Not Useful

peo_hi

The lite version simply suckers you in to purchase the full version ($2.99 US). I tried to test this app out with a half-adder (5 gates) and didn't have enough room to add the inputs or outputs. Not very a useful test if you can't even put in a simple adder.

Why?

This is the laggiest app I have ever used, and how are you supposed to connect parts together, you can change the color of the thing that is nonexistent, how does this make sense?

Useless without premium

I wasn't able to put more than one AND gate therefore limiting me from building simple circuits, if I did something wrong I will rerate but otherwise it's not worth it.

Great idea, needs some work

The app idea is great and I wouldn’t mind paying a few dollars for it, however there is some work that needs to be done. The app itself is very laggy, and the controls seem unintuitive. Just slight things like this need to be done. Maybe a grid lock feature where the whole diagram doesn’t fly around when you tap it by accident? Or possibly just two fingers to move the whole thing. Quick animations will make the whole app seem quicker such as clicking where the gates are or the wiring. Overall though, this is the only app of its kind and has a very niche audience. However, the app has a strong foundation and I look forward to future updates and optimizations.

Update: most problems fixed, but iPhone X notch causes problems

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 REIVEW: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 there seems to be no way to move a gate after placing it other than by deleting it and placing another one. (Edit: they can be moved, but it was at first unintuitive how; and not emphasized much in the help page, I did not initially spot it.) 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. Also it is not made clear what the difference is (if any) between the free and paid versions. The ability to save and load projects is also critical in this sort of app. Overall the app works, but is not user friendly enough for 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!

Function

I finally know how to use this app and it is so great now that I know how to wire! This app is so fun to use! Good job! P.S thx for telling me how to wire

Needs fix

The app crashes upon launch. Will re-rate after I’m able to test the app.

Once you find out how to do it, it’s great!

This is as good as doing it on a computer! It has flip flops and all gates. I haven’t built anything yet in it so I will see about lag. Also I’m not for sure if you can create a intergrated circuit. But it’s really good for it being free! Scrolling with a circuit/gate is a bit too fast.

Dont get

jason robert fortier

There are probbably better apps than this, its extremely laggy, the graphics are extremely bad, and its very unclear how to actually use the app.

Runs VERY hot

And drains the battery at a drastic rate.
