This app is an electronic version of the rubber duck suggested by the book “The Pragmatic Programmer”.
Whenever you are facing a problem which is too complex, to solve it right away: describe it to someone. Describing is the important part, not listening. No buddy at hand? Just describe it to this app instead. The duck will nod when it detects a sound. Hopefully you will gain enough insight to solve your problem. Go ahead, solve your problems in a pragmatic way.
BTW: Have you tried touching or shaking the duck already? ;-)
Important note: This app requires a microphone. Users of 2nd and 3rd gen iPod touch should connect an external mic.
