Great tool for learning

This app is great for learning about circuits and the behavior of different electrical components. Definitely recommend!

Wow.

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.

Best ios app for circuits

tbh best ios app for simulating circuits, even free version can do almost anything, other apps suck because they are either pay to use or barely even functional, this one is just good

If you ever have suggestions or ideas for improvements, feel free to reach out at voltsim.app@gmail.com — we’d love to hear from you!

Must have for electrical engineering.

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!
