Get help with Flight Mode Chat and learn how to make the most of Bluetooth mesh messaging.

Frequently Asked Questions

How does Flight Mode Chat work without internet?
Flight Mode Chat creates a decentralized mesh network using Bluetooth LE. Each phone connects directly to nearby devices, creating a web of connections that relay messages peer-to-peer. No internet, no servers—just direct phone-to-phone communication.

Is Flight Mode Chat really end-to-end encrypted?
Yes! All messages are end-to-end encrypted and never touch corporate servers. Your conversations stay between you and your contacts—no data collection, no tracking, complete privacy.

How far can Flight Mode Chat reach?
Bluetooth LE typically reaches 30-100+ meters depending on conditions. The mesh network extends that range as more people connect—each phone acts as a relay, expanding the network outward.

Perfect for flights—how does it work on an airplane?
Enable Airplane Mode but keep Bluetooth on. Flight Mode Chat uses Bluetooth mesh instead of cellular or WiFi. Chat with passengers nearby without WiFi or cellular—completely offline and compliant with flight regulations.

What happens if one person loses connection?
The mesh network automatically reroutes around disconnected devices. Other nearby users relay your messages through alternative paths, so communication continues as long as there's a connected path to your recipient.

Troubleshooting

Not finding nearby devices

  • Make sure Bluetooth is enabled in Settings
  • Confirm the other device also has Flight Mode Chat open
  • Move closer—Bluetooth LE range is typically 30-100 meters
  • Restart the app if devices aren't appearing after a minute

Messages not sending or relaying

  • Check that Bluetooth permissions are granted in Settings > Privacy & Security
  • Verify there's a connected path of nearby devices to your recipient
  • Toggle Bluetooth off and on to refresh the mesh connection

App crashes or freezes

  • Restart the app
  • Update to the latest version of iOS and Flight Mode Chat
