I’m currently a student studying industrial maintenance, and VoltSim has been a great addition to my DC Theory class. Instead of only working problems on paper, I can actually build the circuits I’m learning about and see how voltage, current, resistance, and other electrical concepts behave.What I like most is being able to calculate a circuit myself and then use VoltSim to test my answer. It gives me a more hands-on way to understand concepts like Ohm’s Law, series and parallel circuits, meters, switches, relays, motors, and other components.I purchased the Core Bundle because I can see myself continuing to use VoltSim beyond DC Theory. As I move further into industrial maintenance, motor controls, PLCs, and troubleshooting, having a simulator where I can experiment without worrying about damaging real equipment is a huge advantage.For a student who learns better by actually seeing and doing things, VoltSim makes the material feel much more practical. I’m looking forward to seeing how far I can take it as I continue my training.

I just paid monthly in another account with another currency.I rated two stars so maybe developers can notice.1. Sometimes can’t edit pins in existing chips. (Can’t save.)2. Sometimes the caret doesn’t move when editing project names.3. Sometimes cannot add new components in a project. (Too many?)4. I want to remove(hide) pin numbers. (I already have labels!)5. Custom chips should be drawn one size smaller.6. I want a “Move” mode to move components without clicking it first.7. I want to double click in most editing modes to activate drag selection.8. I want to copy a part of a project to another project. (Instead of copying the whole project and deleting everything else.)9. When using the “Interact” mode, the “Push” switch should act like a “Push” switch instead of a “Switch” switch.10. When duplicating a group of components, the new copy should appear in totally empty places. (Otherwise it will sometimes accidentally connect with other things.)11. Sometimes “Undo” disables itself and it’s scary. I need more stable “Undo” and “Redo”.12. I need “Rotate”, “Flip”, and “Rotate 180” for groups.13. “Delete” button should be further away from everything else or ask before deleting.14. When duplicating some single objects, I want the new copy to be at right below so I can use them together immediately.15. When adding new components, they should appear near the center of the screen. (The biggest problem for new users to continue using.)16. I want to use(copy) a group(like bulbs) in another project without it being a chip.

This is honestly one of the best apps out there, better than other apps requiring either enormous amounts of ads or a 20 dollar subscription, but you guys only do a dollar a month, really cheap, i will think about getting it some time soon I suppose.

This app is the closest thing to mobile MultiSim that I have ever used. I recommend it to anyone looking towards increasing general circuit understanding and design. The developers of the app are incredibly easy to work with, and the price for the analysis packages is an absolute deal!
