Use cases
Built for when it matters most
Whatever the situation — lost in a crowd, off the grid, or just wanting communication that nobody can monitor — Ndevar has you covered.
Lost your group? Not anymore.
Fifty thousand people in a field, every tower overloaded. Ndevar uses the crowd itself as the network — the more people, the better it works.
- Works when every tower is overloaded
- Share your location in a message — friends get a compass bearing and directions to find you, offline
- The bigger the crowd, the better it works — more nearby devices = better routing
- No app account needed — share and go
Lost you at the gate. Can't call or text — zero bars

- Works in areas with poor or no coverage
- Broadcast channels for announcements
- No platform dependency — works even if Ndevar servers are down

No phone number. No email. Just you.
Most messaging apps require you to hand over a phone number or email address before you can say a word. Ndevar doesn't. Your identity is a short contact address generated on your device — nothing more. No account needed, nothing linking you to a real-world identity unless you choose to share it.
- No phone number or email required — ever
- Your identity is a short address, created on your device
- Share only what you choose — display name is optional
- Works completely offline — no server ever sees you connect

When networks fail, people still need to communicate.
Evacuation centres, emergency shelters, disaster zones — exactly the situations where you most need to communicate are the ones where cell towers are overloaded or offline. Ndevar works through the crowd itself, no infrastructure needed.
- Works when towers are overloaded or offline
- Communicate across an evacuation centre or shelter
- No account or setup required — works immediately
- Share your location as a compass bearing, offline
