Audio guide, no hardware
One microphone. Many ears. No hardware.
OnVoice turns everyone's phone into a tour guide receiver. Your group tunes in with the smartphone they already carry — no receivers to rent, charge, or sanitize.
The problem
Hardware tour guide systems solve the wrong problem
Receivers, headsets, charging cases: a lot of logistics just to let a group hear one voice.
Hardware to manage
- Renting and maintaining dozens of receivers
- Batteries to charge, headsets to sanitize between groups
- Group size capped by how many receivers fit in your bag
- If a receiver breaks or goes missing, it's on you
They already have the receiver
- Zero hardware to buy, charge, or sanitize
- They tune in within seconds using their own phone
- Works for groups of 5 or 500, with no physical limit
- Same audio quality as the guide's microphone, anywhere in the group
How it works
Three steps, zero hardware
The same simple flow you see in the app: the guide goes live, the group tunes in.
01
The guide goes live
Create a session in one tap: session type, title, and you're live.
02
Shares the frequency
A number to read aloud or a QR code to scan: the group tunes in within seconds.
03
The group tunes in
Each listener hears through their own headphones, at the same audio quality as the guide's mic.
Use cases
For anyone speaking to a group on the move
Guided tours
Cities, open-air museums, wineries, markets: the group follows and hears you, even at a distance.
Courses & training
Large classrooms, workshops, outdoor training: everyone hears clearly, no passing microphones around.
Museums & institutions
Assisted tours and guided visits for cultural institutions.
The app
The same app, guide and listener
A minimal interface: whoever is broadcasting is "in the studio" (dark background), whoever is listening is out in the world (light background).
