OneVoice

OneVoice turns your phone into a synchronized karaoke experience for large events. 🎤✨

With OneVoice you can:
• Sing in unison
Join the show and sing along with lyrics in real time.

• Remote control for organizers
An administrator starts karaoke with a simple flag in Firebase, triggers the countdown, and distributes the lyrics instantly.

• Flash and visual metronome
Your camera flashes to the beat of the music to create coordinated light shows in the stadium.

• Smart countdown
A preview screen shows the percentage of connected users and notifies you when the song starts.

• Offline mode and automatic retries
If someone loses connection, OneVoice retries syncing without interrupting the party.

Why choose OneVoice?
