Who we are

WiFiClash
Room

WiFiClashRoom builds real-time digital solutions that connect people — on the move.


Born from academic research at the ETSIT · Universidad Politécnica de Cartagena, we started with a simple idea: stream a teacher's voice live to every student's phone — no apps, no hardware, no friction. That original tool is still alive as WiFiClashroom Education — free for teachers, forever.


That same core technology now powers our products for tour guides, urban explorers, and live experiences around the world. Everything we build is lightweight, real-time, and works on any smartphone.

Origin story
2016
WiFiClashroom is born — a real-time audio streaming system developed at ETSII / UPCT to solve classroom acoustics problems. Students hear the professor crystal-clear on their own phones.
2020
The vision expands. "It would be perfect for tourist groups, who usually have no way to hear the guide well. Moreover, COVID made things very difficult: sharing hardware was not an option". The technology leaves the classroom.
Now
Two products, one platform. TourGuidePro for professional guides who need a monthly subscription and full features. TourGuideLite for guerrilla tours — buy credits, start instantly, no commitment. PayPal or Lightning Network accepted.
