About this app

Crowdr - Take an active part in the show, join the rest of the crowd for an interactive experience.

Crowdr is a new generation technology that creates an interactive synchronized experience of sounds and lights for concerts, festivals and corporate events, using video and audio technology.

Imagine, every cellphone in the entire crowd starts playing the same music at the same time as the singer enters the stadium or changing screen color during the show to light up the arena with an exceptional synchronized light show experience.

- Entire Crowd sound sync
Join the rest of the crowd as all your smartphones play the same sounds, creating a powerful synchronized live show experience.

- Entire Crowd Light sync
Join the rest of the crowd in lighting up the arena through your smartphones, creating a synchronized unique light show

- No internet connection required
We know that in a crowded place there’s a bad cellular reception,our technology doesn’t require any data connectivity.

How do all the phones start at the same time?
The technology we have developed allows the event operator to send commands to all audience devices in real time

What permissions does the app use?
While you are not on the show- the app does not perform any action and does not use any data from your device. Only when you get to the show, entering the stadium and turns on “Live” mode – the app starts “listening” and recognizing the sound to synchronize with the rest of the crowd.

Is it secure?
Our technology is encrypted and ensures that only the show operator can synchronize your phones during the live show.

How much does it cost?
Totally free.
