100% inaccuracy

I have tried playing dozens of traditional irish tunes on my penny whistle, and have yet it have it successfully identify a tune. I try playing with no ornamentations, and with a robotic tempo, and still no success. Ive tried humming and whistling too, with still no success. Not sure how others are getting good results. Im using an iPhone 4S with iOS 7.
