iCircuit is an easy to use circuit simulator and editor on your iOS and, recently, Android phone. It's a perfect tool for engineers, students, and hobbyists who are on-the-go and need a quick look at how a circuit works.
As the creator said,
The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a touch interface to control the total time displayed and stacked and unstacked modes to easily compare signals.
Basically it's a simulator built for studying simple electronic circuits or a component. Touching a component will display an oscilloscope to see what is happening on the waveform at that component. I've used this once to show how a power supply works - rectification, filtering, regulation.
Supported elements include:
- Signal generators, Voltage sources, and Current sources
- Resistors, Capacitors, and inductors
- Manual SPST/SPDT Switches, and SPST/SPDT relays
- Diodes, BJ Transistors, and MOSFETs
- Speakers, Buzzers, and LEDs
- ADCs, and DACs
- Logic gates: AND, OR, NAND, NOR, XOR
- JK and D Flip-flops
Its also loaded with sample circuits to see the app in action

iCircuit is really a handy app so try it out yourself!
