Your voice is drawn against a chromatic grid so you can instantly spot which notes you're nailing and which ones need work.
Warm-ups, scales (major, minor, pentatonic), arpeggios, sirens, and more — all synthesized on the fly for your vocal range and key.
Upload any audio file and sing along. Your pitch curve is overlaid against the reference so you can measure accuracy note by note.
Get real-time feedback on your vibrato rate (Hz) and depth (cents) while you sing.
