Great app!

I'm taking a circuits class now, and this app helps summarize the major concepts in a way that is easy to understand. There are examples of each concept and circuit calculators for each topic.
I downloaded this app hoping to have practice problems with an instant way to check answers.
I think if this app had practice questions like the examples, it would definitely help people get circuits fast, and I would give it 5 stars without a second thought. It would also be great to have examples and practices with superposition, node, and mesh analysis.
Overall, it is clear a lot of work and expertise went into the creation of this app, and so far I have found nothing like it in the App Store.
Thanks for making this app and happy 5th anniversary to Sigma Sky!
