Offline Anonymous Nearby Chat
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Ever felt completely cut off with no signal?
RelayChat is a new way to reach the people who matter, in places where the internet and cell networks simply don't reach.
Using its own mesh network technology, phones connect to each other directly and relay your messages onward — hop to hop, like a bucket brigade.
A lifeline to family and friends during a disaster. A way to stay connected with your group at a festival or out in the wild.
Your everyday conversations become your emergency preparedness.
Turn "no signal" into peace of mind — with RelayChat.
【Why RelayChat】
▼ Connects even with zero signal
RelayChat uses Bluetooth to let phones talk to each other directly. You can send and receive messages even where there's no internet or carrier signal at all.
▼ A network that grows as you do — mesh networking
Every phone becomes a relay point. The more people using RelayChat nearby, the further your messages can travel.
▼ Privacy-first, anonymous by design
No sign-up, no personal information required. End-to-end encryption keeps your conversations locked down, so you can chat safely and with confidence.
▼ Built for moments like these
In a disaster or emergency
When earthquakes, typhoons, or other disruptions knock out communication, check in on loved ones and share information with people at evacuation shelters.
At festivals and events
Crowded venues and packed live shows often jam cell networks — RelayChat keeps you connected with your group so no one gets lost.
Outdoors and while traveling
From mountain trails and campsites to unfamiliar signal conditions abroad, stay in touch even when reception is unreliable.
In everyday dead zones
Subways, tunnels, or airplane mode — talk to people nearby without needing a single bar of signal.
【Please note】
This app uses Bluetooth. For the best experience, please keep Bluetooth turned on while using the app.
Communication range varies depending on obstacles and environmental conditions.
