About Ritmus

Every screen, in rhythm

Ritmus turns thousands of phones into one synchronized canvas — so every crowd moment feels designed, not accidental.

Why we exist

Traditional crowd engagement — lighters, phone flashlights, glow sticks — is beautiful but uncoordinated. We give event organizers pixel-level control over every attendee's screen in real time: synchronized color washes, media playback, live polls, and gyroscope- and sound-reactive visuals. All of it runs in the browser, so no one in the crowd has to install a thing.

What we build

One platform to choreograph the entire room — before, during, and after the show.

Synchronized screens

Push colors, gradients and media to every phone at once — live from the organizer's control room.

Interactive modes

Story reels, gyroscope-reactive color zones, microphone-driven ambient visuals, and pre-programmed sequences.

Real-time engagement

Polls, likes, comments and attendee Spotlight submissions — all flowing live during the event.

No app required

Attendees join from a single link in their browser. Nothing to download, nothing to install.

Built to scale

From a 10-phone living room to a 50,000-phone festival, the same engine keeps every screen in sync.

Privacy-first

Consent-based analytics, transparent data handling, and we never sell your personal data.
