iCircuit

Using N-channel MOFSETs as a switch doesn't appear to work. The MOFSET always allows current through regardless of whether the gate is open or closed.

This is a great app, but the windows version doesn't seem to have subcircuits built in. Strangely you can actually use subcircuits if you import a file containing one from IOS, and they seem to work fine. You can even modify which circuit the subcircuit is pointing to, just can't place new subcircuits or place ports to create a subcircuit file. Seems like a very strange omission, I hope they fix this soon. Also, this needs an simulation on/off switch like the IOS version. There is no reason I need to waste the CPU cycles and battery life by simulating the circuit constantly when I'm building the circuit. Sometimes with complex circuits the simulation will make the interface sluggish. On IOS I can switch the sim off while I'm modifying big circuits to avoid this issue. Just allow the user to turn on/off the simulation at their own discretion please! With these two (very simple) changes this is a five star app for sure.

0 stars. I paid those 5 dollars just to be able to have subcircuits, which the icircuit home page said it had! This app wasted my five dollars!

I used this app to draw out the different circuits in the book Code. It brings the already excellent examples to life. For me as a novice this is a great app for getting a grip on Logic. It only took me twenty minutes to get a grasp on the user interface. The zoom feature is really awesome.

the component you are editing will be deleted if you use the delete button during the edit, such as when editing the name. it's super annoying. great app otherwise! it would be great if there was a library of circuits that the community has built so we can download and share ideas.
