Geogram

When the internet goes down, most apps stop working. Geogram keeps going.

Geogram connects people directly - phone to phone, laptop to laptop - without requiring servers, accounts, or infrastructure you don't control. Messages hop between devices over whatever path works: WiFi when available, Bluetooth when it's not, internet when you want global reach.

Every message is signed with cryptographic keys, so you always know who you're talking to. No spoofing, no impersonation, no "trust us" from a company that might not exist next year.

Built for communities that need to communicate when things get difficult: remote areas, disaster response, places where the network is censored or unreliable, or simply people who believe their conversations shouldn't depend on corporate infrastructure.
