Free while in beta
Every phone in the room becomes one light.
A stadium, a ballroom, a gym. Everyone scans one code, and every screen in the place lights up together — in time with the song, in the colours you chose. There is nothing to install and nothing to hand out.
No card. No per-guest charge. No limit on the size of the crowd.
How it goes
Three things happen, and the rest is the song.
People scan one code
One QR code for the whole room — on the screen, on a card, in the programme. It opens a web page, so there is no app to download and nothing for anyone to sign up for. A phone that joins late catches up on the next beat.
One question splits the crowd
Ask something people already know the answer to — home or visitor, bride or groom, which section are you in — and their answers become the groups the show moves between. Or skip it, and the whole room acts as one.
The song becomes the show
Pick the track. Wildlights listens to it — the beat, the sections, the drop, the separate instruments — and writes the show from what it finds. You choose how big it should feel, from a slow wash to the full thing, and watch it back before anyone arrives.
Where it works
Anywhere a crowd is holding a light and looking the same way.
Stadiums and school sport
Friday nights, homecoming, the student section, a cheer routine timed to the mix.
How it works in a stadium →Weddings
The first dance, the last song, and the question everyone wants to answer on the way in.
How it works at a wedding →Concerts and festivals
The crowd becomes the rig — even when the music is coming from someone else's desk.
How it works at a show →Conferences
Brand colours across a ballroom, and a keynote moment people actually remember.
How it works at a conference →What makes it hold together
The hard part is a thousand phones agreeing on now.
Everyone on the same clock
Phones keep time against the event's own clock rather than their own, so the room lands on the beat together instead of in a ripple. In simulation, 300 phones sat within 50 ms of each other 99.8% of the time.
It follows the DJ, not the other way round
When the music is coming from a PA, a band or a DJ, the host phone can listen through its microphone, work out where in the song the room actually is, and line everyone up with it.
Flashing you can answer for
Three settings, the middle one capped at three flashes a second — the usual public guideline. The limit is measured on what a phone will really show, not on what the show intended. How that works.
Watch it before the night
The preview runs the real show through the real engine on a room of simulated phones. What you see on the laptop is what the room will do.
The music never leaves your device
Your song is analysed in your own browser. What reaches the server is the light show — colours and timings — never the audio.
You are still in charge
Run it live: start the show, light one group, take the room to black. If something is wrong, one button stops everything.
Try it on an empty room first.
Make an event, pick a song, and watch the show back before you show anyone. It takes a few minutes and costs nothing.
