I've been using this on my Android phone for about a month now. Brilliant bit of software. Schematic design and simulation with Virtual CRO, Voltmeter, Ampmeter etc...
I use it to draw up quick simulations for customers for more in-depth discussion of their own circuit ideas.

Also available as a Chrome app and on iOS as well. Seems like a pretty cool tool.
