Turn the crowd into a light show

FlashSync listens to your live set, finds the beat in the browser, and flashes the whole crowd's phones together

One link. The whole crowd in sync

Hard engineering, hidden behind a link.

FlashSync does something incredibly difficult: it detects the exact beat of a song in real time, right inside your web browser, with zero noticeable delay. It can keep hundreds of devices perfectly synced to the same music simultaneously. Usually, this level of split-second precision requires installing heavy, specialized software but FlashSync pulls it off through a single, standard web link.

Easy and simple user experience

From link to light show in seconds.
