Has potential (pun unintended). Visually pleasing, but it is hard to make any circuit with. For example, you have a simple circuit, and you want to move one component. Instead of flexing the entire circuit, that component is detatced completely, and now you have to reattach it. Like I said, the app has potential, but it is just a toy right now.

Thanks for sharing your thoughts! You can move components from their pins without completely detaching them from the circuit. It's not perfect, but we're always trying to make things easier. Your feedback helps us improve the app for everyone. Thanks again for your input!

I would love this app. 2 problems. For me the circuit would not run. Had Power, current source, ground, resistor. Voltage did not show anywhere in circuit and there was no current flow. Plus a transformer needs to be added and transistors need to be real world models if this SIM is to be useful.

Thanks for your feedback! The app is made for learning, not advanced simulation. For now, we focus only on simple and generic elements to keep things easy. To see voltage, tap on the element or use a voltage source. Thanks again!

update: the dev is working on a fix. will update again when this is fixed. connecting a lamp directly to a battery (+ to +, - to -) and adding both ends of (two switches in series) to the positive terminal of the battery (where only bulb positive terminal is connected) causes switches to work as an xor 😭🙏 I'd guess it cannot handle 2 or more connections to the same wire/terminal

Thanks for your feedback! It looks like there might be a problem with how the switches are connected. Could you please send us a screenshot of your circuit to elhaouzi.abdessamad@gmail.com? That will help us see what’s going on and fix it.
