Fly Casting Analyzer(F.C.A) Free
F. C. A Free is a neat piece of software that allows you to both visualize and analyze your fly-casting using the accelerometer on the iPhone.
Through using your iPhone in place of your fly rod, the F. C. A simulation measures your casting stroke velocity and displays your results in a graph format from which it is easy to find out your current strengths and weaknesses.
F. C. A. will aid you in acquiring the key skills needed for fly-casting: power, acceleration and timing.
