Audience orchestration
A whole crowd becomes
one display.
A Tonebeam smartphone light show turns thousands of phones into one synchronized, pixel-mapped display — choreographing light, sound and haptics across an entire venue, in sync, with no one installing an app or entering a seat number.
What is a smartphone light show?
A smartphone light show turns the audience’s own phones into one giant, coordinated display. Instead of handing out LED wristbands, every phone becomes a pixel — and together they paint waves, text, colour and imagery across a stadium, arena or festival, perfectly in time with the music or the moment. Tonebeam makes it pixel-mapped: because each phone knows its place in the venue, the picture lands on the real crowd, not a rough guess.
Every phone is a pixel.
Because Tonebeam knows where each device is to the centimetre, the crowd itself becomes addressable. Patterns sweep the stands as one continuous canvas — waves, text, ripples, brand moments — mapped to real seats, not guesses. Move across it.
Phones, not wristbands.
LED wristbands mean hardware to buy, ship, charge and hand out to every single seat — one colour, one show, then landfill. A Tonebeam smartphone light show uses what the crowd already holds.
- Nothing to hand outNo wristbands, no tags, no app — people just open a link, so it scales to any crowd instantly.
- Full-colour, pixel-mappedRender real text and imagery across the stands, not a single flat colour.
- Works when the network doesn’tRuns on the device and can play fully offline in a packed, signal-starved venue.
- Far less per headNo per-seat hardware to manufacture and distribute show after show.
No app. No signal. No problem.
Even with every network down, the show is driven over sound from the venue's own system — phones are passive receivers, so it simply plays. No internet, no downloads, no permissions to grant, and their speakers are never used. That's what makes a packed, network-starved venue still light up as one.
Light, sound, and motion — in sync.
Light
Screens and torches become a stadium-scale display: waves, sweeps, pixel-mapped text and imagery across the stands.
Sound
Per-zone audio cues fire in lockstep, so the crowd hears as one — or in deliberate, spatial waves.
Haptics
Coordinated vibration adds a physical layer to a drop, a goal, or a reveal — felt across the whole bowl.
Where it shines.
- Stadiums & sporting eventsOpening ceremonies, half-time moments, and crowd-wide reveals that turn the audience into the spectacle.
- Concerts & festivalsChoreography that tracks the set — the room responds to the music in real time.
- Weddings & private eventsA unique, app-free light show for a few hundred guests, with nothing to set up or hand out.
- Brand activationsApp-free, instantly scalable crowd moments for launches, sponsorships, and broadcast.
Smartphone light shows, explained.
What is a smartphone light show?
A smartphone light show turns the audience’s own phones into one giant, coordinated display. Instead of LED wristbands, every phone becomes a pixel — together they render waves, text, colours and images across a stadium, arena or festival, in sync with the show.
How do synchronized smartphone light shows work at concerts and sporting events?
Every phone knows exactly where it sits in the venue, and the whole crowd is driven as one — synchronized over sound to about ±10 microseconds. Phones are passive receivers, so there’s nothing to install and no signal to lose.
Do fans need to download an app?
No app needed. It runs in our app, a partner’s app, or straight from a link — nothing to install, no account, no seat number to type.
Does it work if the venue network is overloaded or there’s no signal?
Yes. The show is driven over sound from the venue’s system, so it still plays even fully offline — exactly when packed-venue networks are saturated.
How is it different from LED wristbands?
Wristbands are single-colour hardware you buy, ship and hand out to every seat. Tonebeam uses the phones people already carry, renders full-colour pixel-mapped imagery rather than one colour, and needs nothing distributed — so it scales instantly and costs far less per head.
How many phones can it drive at once?
From a few hundred guests to a stadium-scale crowd of tens of thousands, all driven as one synchronized, pixel-mapped display.
