AzMesh: Offline Chat & Files

AzMesh connects phones directly to each other over Bluetooth and Wi-Fi. It needs no internet, no server and no account — your messages travel from phone to phone. If someone is out of range, the phones in between pass the message along. Two people who cannot reach each other directly can still talk through the devices around them. WHAT YOU CAN DO • Send text messages to a specific person, or broadcast to everyone in range • Record and send voice messages • Share photos, files and your location • Send an SOS to everyone nearby • See a live map of who is reachable and how far away they are • Make voice calls over the mesh BUILT FOR WHEN THERE IS NO SIGNAL • Hiking, camping and mountains • Festivals, stadiums and crowded places where the network is saturated • Power cuts, earthquakes and other emergencies • Flights, boats, remote work sites • Anywhere mobile data is down or unavailable PRIVACY BY DESIGN • No servers. Your messages, location and files are never uploaded anywhere. • No account, no phone number, no email required. • Free with ads (Google AdMob) — never in chats, calls or SOS. Anonymous usage statistics (Google Analytics) help improve the app; message contents are never collected. • Direct messages and calls are end-to-end encrypted (P-256 key exchange, AES-GCM). Phones that relay a message cannot read it. • Your identity comes from a key pair generated on your own device, so nobody can send messages in your name. • Messages sent to the "Everyone" room are public to the mesh on purpose — the app tells you this clearly on screen. LANGUAGES Azerbaijani, English, Russian and Turkish. HOW IT WORKS AzMesh uses Bluetooth and Wi-Fi Direct to find nearby phones running the app and builds a mesh network between them. The more people nearby who have AzMesh, the further your messages reach. Keep the app running so your phone can stay part of the mesh and pass messages along for others. NOTE AzMesh needs at least one other person nearby running the app. It is not a replacement for the mobile network — it is what you use when there isn't one. Location permission is required by Android itself for Bluetooth scanning on older versions; your location is only shared when you choose to send it, and it never leaves the mesh.
