From Pat Colucci:
Divvy enables the freedom to chat, share photos, videos, and files without an Internet connection. How is this possible? Divvy uses 'Multipeer Connectivity, which enables nearby devices to communicate over infrastructure Wi-Fi networks, peer-to-peer Wi-Fi, and Bluetooth personal area networks. Connected peers are able securely transmit messages, streams, or file resources to other devices without going through an intermediary web service.Whether you're on the subway, on vacation, on an airplane, or out camping; Divvy allows you to use your iOS device without any borders.Divvy was built on Apple's innovative new programming language, Swift, to operate smoothly on all iOS devices including the iPhone 6, iPhone 6 Plus, and iPad Air 2.
