It's the best app of this type I've ever used. Concepts are explained better than in books, and also animations are of great help. I hope there is a plan for more learning content, like transistors, diodes, etc. This app is a masterpiece, and definitely worth the money!

Really clear explanations and animations, I think I will buy the pro version soon, once I've finished the free lessons. Occasionally there is a grammatical error that makes it hard to understand a sentence, but apart from that lessons are well written and easy to follow. I look forward to new lessons being added in the future
