iCircuitís circuit designer and simulator for those on the go!
Circuit design and simulation isn't restricted to PCs alone as the mobile device market has seen a rise in the number of apps catered toward engineers on the go over the last few years. EveryCircuit, Circuit Simulator and Electrodroid are some of the more popular free mobile apps available for download, 
however for real-time design and simulation on almost any platform, iCircuit is quickly taking the crown. So why is it different from the others mentioned above? Simple, it's always running simulations even through the design process, like playing with the circuit with the power on. The app boasts over 30 elements for circuit design, including resistors, MOSFETs and digital gates and incorporates a handy multimeter to instantly read currents and voltages anywhere along the circuit. There's even a built-in oscilloscope to track multiple signals and see how those values change over time! The only drawback of using iCircuit is that user's need an updated mobile device with multiple CPU cores, as the app is a resource hog. The free app is available for Apple's iPhone and iPad as well as Android and Windows-based mobile devices.

ICircuit is not Free

In the article number 7. The author wrote this app is free but it is not.

For viewing Gerber files I recommend GC-Prevue from www.graphicode.com.  It is a free Gerber file viewer.  They also have other more-capable purchasable tools.

Add QUCS to the Free Design Tools

Quite Universal Circuit Simulator (QUCS) is a great little Spice-like open-source tool that runs quickly, has a wide range of components, rather intuitie interface (but a so-so manual), and will execute S-parameter analysis. Available at qucs.sourceforge.net/.

I've used Eureqa by www.nutonian.com, sounds similar.  There's a useful but limited free version.

I have tried FreePCB couple of times, it is not bad for most projects with 16 layers or less. Some features I wish it had are viewing Gerber files, import/export of DXF files and print capability!

What is the basis of this ranking?

Is this ranking based on a survey of engineers? If so, what is the size of the sample and how was the sample chosen?

:-)  Yes, it can be a rare commodity when engineers interact with non-engineers!  Oh, well, c'est la vie!

I cannot disagree.  I suppose I've been lucky a lot of the time; I usually have the opportunity to insist that things are done properly.  I don't take that for granted. ;)

Not disputing that.  But time is a constraint that must also be accommodated...and meeting the schedule is not always "not good engineering." 

 

I think we have to meet in the middle here.
