In the field
Wherever there's
a guided tour.
From Egypt to Saudi Arabia, on sightseeing tours and Hajj journeys, groups of 50 listened to their guide through a single QURB device.

Tour guide system
A modern alternative to
walkie-talkies and whisper systems.
For years, tour guides have relied on walkie-talkies, transmitter-receiver sets and shared headsets to reach their groups. With these systems a device is handed to every guest, collected after the tour, recharged, and lost units have to be tracked down.
QURB is a tour guide broadcast device: it creates its own local Wi‑Fi network and streams the guide's voice to the guests' own phones. No channels or frequencies to set, no internet required. The group listens through the free QURB Live app or the browser.
Built for cultural tours, museum visits, Hajj and Umrah groups, city tours and corporate trips. One device supports up to 70 people.

Frequently asked
Your questions, answered.
Is QURB a walkie-talkie?
No. QURB is not a two-way radio or an RF receiver system. It is a tour guide broadcast device that delivers the guide's voice to guests' phones over its own local Wi‑Fi network, a modern alternative to walkie-talkies and whisper headsets.
Does it work without internet?
Yes. QURB creates its own local Wi‑Fi network and broadcasts audio without any internet connection. Internet sharing is an optional feature.
How many people can listen at once?
A single QURB device supports up to 70 people. For the smoothest experience in the field we recommend groups of 50–51; field trials were carried out with groups of 50.
Is the app free? Do guests have to download it?
The QURB Live app is completely free on the App Store and Google Play. Downloading it is not required either: guests can join the QURB network and open live.qurb in their browser.
Will guides get used to it? Is it suitable for older guides?
Absolutely. QURB doesn't ask guides to learn anything new. There are no complicated steps like setting frequencies or handing out devices; the guide simply keeps talking.
What is the range?
In a measured field test, listening was trouble-free at 130 metres. Actual range depends on the environment and obstacles; it works comfortably at the distances a tour group stays together.
How long does the battery last?
QURB is built for long tours. The base has a removable power bank mount; swap an empty power bank for a fresh one and keep going all day.
Can several guides use it in the same place?
Yes. Each QURB device creates its own independent network, so several devices can be used at the same location without interfering.
Can it be used for Hajj and Umrah groups?
Yes. QURB has been used in field trials with Hajj and Umrah groups in Saudi Arabia. Since it needs no internet, you don't depend on the mobile network in crowded areas.
Rather than describing it,
try it on a tour.
Pilot use comes with training and technical support.
