Core capabilities
Real-Time Pitch Feedback & Scoring
Evaluates whistling pitch in real time during tune practice, indicating sharp or flat notes and quantifying how much the pitch drifted off-key.
Range Transposition & Tempo Control
Allows users to shift songs up or down in one tap to fit their whistling pitch range without affecting score, and drop playback to half speed while learning phrases.
