Only one of the three horns is somewhat like an air horn, but it isnt a constant blowing horn -- it repeats the sound in a few, five seconds. Its not even loud enough to wake my teens get up.

Sorry creators, try again and make improvements! ~HP~ Okay, I just read that the maker was "15yrs old", so he deserves a few claps! It makes sense now, why the app lakes experience. Keep at it young man, youll be bringing home the bacon soon!
