As a practicing EE I find this very useful. Recently I designed a low pass filter on the bench for a quick-and-dirty application. It would have been helpful to have been able to share the component values and design information. Copying them out by hand seems unnecessary. Give me a sharing method and I will happily upgrade to 5 stars.

Why it does not allow me to calculate parallel resistor value? It seems like a bug. There is no way to select parallel mode. Same for capacitor and inductor.

This is a very useful app but the latest update won't run on my Samsung S6 running 5.1.1. It crashes on launch. UPDATE - Fixed in less than 24 hours! Very impressed!
