Voice Choir
Every phone listens to one voice. Hum the note on your screen, watch your pitch line slide onto it, and hear the whole room tune into chords and songs.

No login. Your phone works out your pitch itself; no audio is uploaded, only pitch, loudness and confidence numbers about 10 times a second. The big screen plays a synthesized choir rebuilt from those numbers, not people's voices.
