Is there a truly reliable means of communication in an emergency?

What if you could still communicate with people nearby, even when the internet and phone lines are down? RelayBLE is a completely new offline messaging app that makes that dream a reality.

[Key Features of RelayBLE]
・ Completely offline communication
No internet required. Exchange messages directly with nearby devices within the Bluetooth signal range (a few meters to a few dozen meters). Your smartphone becomes a reliable means of communication, even in large-scale communication outages or areas with poor signal reception.

・ Privacy-first design
No user registration is required. Simply install the app and you're ready to go. Plus, by exchanging QR codes with specific contacts, you can have private conversations encrypted end-to-end (E2E). Enjoy secure, private communication between just the two of you.

・ A special social networking site exclusive to you
A physically local community that connects you only with people in the same space. Valuable communication only occurs when you're in the same place, whether it's checking in on safety at an evacuation shelter during a disaster, reporting live at an event, or exchanging information on a crowded train.

・ Secure blocking feature
Block annoying users with a single tap. Once blocked, you'll never receive their messages again. We provide a safe and secure environment for everyone.

[Great for these situations!]
・ Disasters and emergencies: Sharing information at evacuation shelters and checking in on the safety of family members.
・ Events and festivals: Communicating with friends and exchanging information about the surrounding area.
・ Everyday travel: Checking on delays and casual conversations during your commute to work or school.
・ Offices and schools: A secure communication tool within a specific building.
・ In places where you can't speak: Use it to communicate smoothly even in places where it's difficult to speak, such as in a store, for writing notes, for quiet conversations with customers or staff, or for keeping in touch in the library.

[Usage is Simple]
1. Download the app
2. Turn on Bluetooth
3. Start sending messages to people nearby!

RelayBLE offers a new way to connect.
Now, you too can enter the offline world.

[Note]
Due to the characteristics of Bluetooth LE technology, communication stability may be affected by building structure, obstacles, and surrounding signal strength. For important communications, we recommend using other communication methods whenever possible.
