Your crew connected. Your audience listening.
A production intercom for your crew and an audio guide for your audience, on everyone's phone. They join with a QR code, install nothing and get around 150 ms of latency.
Free forever up to 5 people at once. No card needed.

For your crew
Intercom
Channels, positions and a matrix to decide who listens and who talks, just like in a production. Everyone uses their phone as a beltpack.
- Channels for production, tech, security…
- One QR code per position: no accounts, no apps
- Calls, private line and an audio hub for your wired intercom
For your audience
Audio guide
The guide speaks and every attendee hears them on their phone, even if the group spreads out or it's noisy.
- One room for each person speaking at the same time
- A link for the speaker and a QR code for the audience
- Unlimited rooms, as many at once as you need
Intercom
A production intercom, on everyone's phone
Set up the channels, decide in the matrix who listens and who talks on each one and hand out one QR code per position. Everyone joins with a headset and they're on air.
- 1
Create the channels
Production, Tech, Security… up to 12 per intercom, each with its own color.
- 2
Set up the matrix
Each position is a row: turn on the headphones so it listens to a channel and the mic so it can talk on it.
- 3
Hand out the QR codes
Each position has its own. Scan it, type a name and start talking.
Push to talk
Quick tap: the mic stays open. Press and hold: you talk while you hold, like a real beltpack.
All channels on one screen
Switch channels with the arrows or the list, and see when someone talks on the others.
Volume and mute per channel
Each channel has its own volume. Tap the speaker to stop hearing one without losing the rest.
Calls and private line
Call the whole channel or just one person: a line opens for the two of you only.
Audio hub
Send and receive audio through a PC's sound cards to connect your wired intercom.
A channel for the audience
Send a channel to an audio guide room: interpreters, the host or announcements.
Live view
See who's connected on each position and who's talking.
In their language
Everyone uses the beltpack in their own language; change it in Settings.
Audio guide
Your guide, in every attendee's ear
The guide speaks into the mic and every attendee hears them on their phone, in as many rooms as you need. They join by scanning a QR code: nothing to install and no receivers to hand out.
- 1
Create the room
One for each person speaking at the same time. It has two links: one for the speaker and another, with its QR code, for the audience.
- 2
The guide goes live
They open their link on a phone or laptop, no account needed. Using the phone's mic or a lavalier mic: check the level and tap “Start”.
- 3
Attendees listen
They scan the QR code, tap “Listen” and that's it. No apps, no sign-up and no receivers to hand out.
100–200 ms latency
WebRTC audio with Opus and a minimal buffer: what the guide says arrives almost at the same time as their voice in the room.
Unlimited rooms
Open as many rooms at once as you need: your pass only counts how many people are connected. For very large events, we'll put together a quote.
Automatic reconnection
If a phone switches from Wi-Fi to 4G, it reconnects on its own in seconds. It counts as the same person.
Day passes
You pay for the days of your event based on how many people are connected at once, with no subscription or commitment. The guide doesn't count.
Payments and invoices in the app
Passes by card, Apple Pay or Google Pay, and invoices with your billing details.
Guide console
Connected listeners, connection quality and the QR code always at hand.
Who it's for
TV and streaming
Directing, cameras and sound, each on their own channels, with no cables to run.
Theater and concerts
Stage management, tech and front of house coordinated from their phones.
Conferences and trade shows
The crew on the intercom and an audio guide room for each talk.
Simultaneous interpreting
One audio guide room per language and the intercom to coordinate the interpreters.
Guided tours
Museums, cities, wineries: the group hears clearly even when it spreads out.
Security and staff
Channels per area or team, and calls to a single person when needed.
Sports and outdoor events
Organizers, volunteers and production on the same intercom, over mobile data.
Industrial visits
On the factory floor, with noise and hard hats: the guide's voice straight to the ear.
Day passes, no subscriptions
You choose the pass based on how many people will be connected at once (audio guide listeners and intercom members, all together) and how many days your event lasts. Unlimited rooms and intercoms, and free up to 5 people at once.
