Excellent Electrical App

I am an electrical engineer in the US and I use this app almost daily for conductor and breaker/fuse sizing and highly recommend it. I had several questions and tech support was highly responsive.

Reklám!!!

Hiába van előfizetve a pro verzióra akkor is ad reklámot. Ráadásul teli képernyőset. Even if you subscribe to the pro version, it still shows ads. Plus, it's full screen.
