Put your cellphones in the air! With crowdlight, the audience is an additional lightshow. crowdlight analyzes the music and converts it to color. Your screen will flicker according to the music on stage. iPhones with a built in flash will use it as an additional lightsource. Enable Bluetooth and/or WiFi to make crowdlight sync with other devices around you. They'll build a swarm and will split up the low/mid/high frequencies of the music among them. ATTENTION: Bluetooth/WiFi cannot be switched on from within the app. You have to go to your settings panel and switch them on manually. Use it at concerts and in the club and make the band/dj have some fun, too!
