Simple electronics circuit simulation software for Mac I want to learn how basic electronic components work and test some basic sensor output etc. My circuits are really simple so i don't need any fancy stuff.

I think MacSpice is CLI so it's too hard for me, i really need GUI app since i know hardly nothing about electronic circuits.

Which app lists electronic components with real names like "resistor 200" and don't use cryptic component codes which are hard to newbie?
This is one of a kind App http://icircuitapp.com/

It has IPad app as well. with simulation capablities
