Turn every phone into a beat-synced color show.
Create an event, share the QR. The crowd scans, holds up their phone, and the whole room pulses to the music your device hears — split into groups for stadium-scale color blocks and waves.
Scan & join
One QR. Phones land on a single fullscreen color page — zero setup for the crowd.
Beat from your mic
Your laptop or phone mic listens to the room. Bass-driven beat detection drives every pulse.
Group patterns
Waves, blocks, split halves, strobes — automatic group assignment spreads across the stadium.
