With Circuit Lab, you can graphically draw circuits on your mobile device and have them analyzed. Based on the modified node analysis method, this app is an electronic circuit analysis tool that allows users to graphically draw the circuit and then have it analyzed.

Four kinds of analysis
There are four kinds of analysis that may be conducted with this app. There's DC: linear and non-linear circuits with continuous voltage and current sources, AC: linear and non-linear circuits with sinusoidal voltage and current sources, transient: linear and non-linear circuits with sinusoidal and pulse voltage sources, and multi-frequency AC analysis: linear and non-linear circuits with sinusoidal voltage and current sources, which analyzes the circuit behavior in a range of frequencies.
Each circuit can contain capacitors, diodes, inductors, resistors, Zener diodes, and more.
Taking control
Controlling circuits with this app is done with simple gestures on your touchscreen. You can drag your circuit with your finger to move it into the desired position, and to modify the component's parameters, simply tap on a component. For easy viewing, you can zoom in and zoom out by using pinching gestures. If you'd like to reset the position and zoom levels back to their original state, just double tap your screen.
By tapping the DC button, you can get the voltage at each circuit's node, and by tapping the AC button, you can get the voltage phasors at each circuit node, or the bode graph of the voltage at each circuit node. To analyze the circuit's behavior during time and to see graphs of voltages and currents, tap the transient button.
It's simple to store and reuse circuits with this app, and for each component, a brief video is available to show you how to insert it into the circuit and edits its characteristics. Once saved, you can easily print, or share circuits through iCloud, iPad, or in PDF format.
Circuit Lab is compatible with iPhone, iPod touch, and iPad, and requires iOS 5.0 or later.
COST: $6.99
