오프 - 인터넷 없이 만나는 주변 사람들

"What if you could play pranks on the people around you right now?"

[OFF] is a completely new concept of hyper-local wireless playground that requires neither a central server nor carrier data. Using only the Bluetooth built into your smartphone, it scans people in your surrounding space like a radar to create group chat rooms.

Troublesome sign-ups? Exposure of personal information? With [OFF], it takes less than a second. The moment you open the app, start the thrilling experience of connecting with people nearby immediately without signing up!

🚇 Highly recommended for these people!

Boring subway commutes: "Anyone passing Sadang Station on Line 2 right now?", "Anyone who boarded at Gyodae Station, your backpack is open." A real-time witty banter arena shared only with people in the same train car.

Wireless flings within a 10m radius: "Anyone in this car wearing a subtle mint shirt, please wave a carrot if you've read the message." Wireless signal transmission more thrilling than AirDrop!

Data-crippled festivals/baseball stadiums: When there are so many people that even KakaoTalk doesn't work! Connected by a stepping-stone network among ourselves, real-time festival group chats are activated with messages like, "Let's all turn on our phone flashlights for the encore song," and "I'm jealous of the home run ball in the third base outfield seat."

Apartment resident group chat without verification: "I'm at the Building 103 playground right now; is there anyone who can urgently lend me a green onion?" Communicate instantly with your closest physical neighbors without needing to sign up or verify your identity.

🛑 Important Notice Before Use

Since this app uses direct wireless communication technology between devices, it is most active when users are gathered in close proximity to each other. We would like to inform you that, as there is no central server, the developers can never collect or look into users' conversations.

Turn the internet OFF for a moment, and let's stay ON!
