Sing a note. Watch it land.
Your voice shows up as a coral dot on the spiral, with your harmonics stacked above it. Drift a little flat and you see it the moment it happens. No grades, no lessons. Just you and the note.
This is the soundcheck. The app is quicker, does far more, and is free on iPhone and Android in November. Premium adds your session card, 5‑minute clips and premium themes. See the app

Your set list.
Hit the spoke
Pick a note and a coral ring marks it on the spiral. Sing until your dot sits inside it and hold it there. Most people miss on the first try.
Hold a long one
Sustain a note and watch your vibrato swing either side of the spoke while your harmonics keep their shape above it.
Watch the take you didn't plan
Sang something good? One tap replays the last 5 seconds, so you can watch it again.
