A very nice application

iCircuit is a wonderful app to build up electronic circuits. It has most of the common components to set up simple circuits and lots of tools to enquire currents and voltages along points in your circuit. Of course it is not a professional tool, but it is excellent for students and hobbysts alike, and it is worth the $10 that the author is asking. Minor annoyances are the difficulties to manipulate components using fingers,I would love to have a mouse instead. Other weak point is the manual that could be better. I still could not figure out how to use the osciloscope and the manual did not help it.
