Do I need internet or a SIM card? No. Raven Mesh connects phones directly over Wi-Fi Direct or Wi-Fi Aware. No cell signal, no Wi-Fi router and no internet connection are required for chat to work between phones that are in range of each other.
How far apart can two phones be and still connect? This depends on the phones’ Wi-Fi hardware and the environment - typically similar range to a Wi-Fi Direct file transfer, commonly tens of meters, more outdoors with clear line of sight. Messages can also hop through other phones in the mesh to reach someone out of direct range.
What happens if I lose connection to someone mid-mesh? Raven Mesh queues messages addressed to a peer that’s out of range and delivers them once a path to that peer is available again, either directly or by relaying through another phone in the mesh.
Is there a free version? Yes. The free tier supports a small mesh. A one-time in-app purchase removes the peer limit permanently - no subscription.
How do I leave a mesh or wipe my data? Go to Network > Leave mesh to leave and clear local mesh data, or Settings > Clear data to reset the app entirely. If you’ve set a duress PIN, entering it at the lock screen wipes local data (messages, media, mesh membership) behind a disguised error screen.
See the Privacy Policy for exactly what data the app touches and where it goes.
