The Click Heard app is a tool that assists dog trainers to see a graphical history of their clicker training sessions. What Click Heard does is listen (hear) for the frequencies made by your own clicker and records the date and time for each click made for the current clicker training session. This can be particularly useful for professional dog trainers but can also help individual dog owners in understanding how, over time, their dog clicker training sessions can be altered to produce better results. Click Heard uses digital signal processing (DSP) and the Fast Fourier Transform (FFT) method to detect the frequencies of dog clickers.
The Click Heard app is the same as the Click Hear app except that Click Heard is free and only works on the iPhone and iPod Touch and uses Apple iAds.
