Three minutes of singing.
A measured map of your voice.
A guided tone ladder finds your true edges, then a free sing maps your comfort zone, strongest note, pitch tendencies, and vibrato — measured, not guessed.
Everything runs on your phone. Your voice never leaves it.

Match each tone I play. We'll climb until it breaks, then walk down to your floor. Flips into falsetto are data, not failure.

90
Sing anything you love, a cappella. Quiet room, phone at arm's length. Slide to your lowest and highest comfortable notes somewhere in there. Recording stops itself at 90 seconds.
