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.
