Boomi - Every Phone, One Sound

Boomi turns multiple phones into one synchronized speaker.

No Bluetooth speaker needed. Place the phones side by side and let
them all play the same music at the same time.

HOW IT WORKS
• One phone creates a room and shows a QR code
• Other phones scan the QR or type the 6-character code
• Pick a song, press Play — every phone starts together
