Dart - Festival Chat App

Dart is an app for festivals that allows people to communicate in places where normal phone signal fails. It uses Bluetooth to allow messages to be sent between devices. If any other Dart users are in range, they will relay messages between other users, allowing communication over greater distances.

If you're stuck in a crowd trying to find your friend, activate DartChat and anyone else nearby with the app will bounce your messages to your friend.

The app uses low energy bluetooth (same as your smart watch) - so very little battery drain.
