About this app

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?
- **Scalable**: Works on thousands of simultaneous devices.
- **Low power**: Optimized to reduce CPU and battery usage.
- **Easy to use**: Simple interface, no pre-event hassles.
