Whistle in tune: a live pitch line against the target note
Whistling Tutor listens through your microphone, draws your whistle as a live line against the note you are aiming for, and tells you in cents how close you are. When you miss, you get one named hint within about a second: a little higher, a little lower, you skipped a note, start right on the note, or hold it steady.
