Phrase Echo maps your voice note by note and shows you your exact pitch accuracy in colour —
green for spot on, orange for close, red for off. Tap any note to hear what you sang
vs. pitch-perfect. The corrected version loops immediately so your ear recalibrates on the spot.
Then you sing it back and try to beat yourself.
