About Swÿp

Pronounced 'Swipe.' The goal of Swyp is to allow any two apps to communicate with each other with a simple gesture bridging two touch screens.


The core principal of Swyp is "if you export data, you support png."

  • Swyp apps will have native file formats, and usually support many formats, but they must export PNG.
  • Swyp supports streaming-data pathways for music, video, or multiplayer games.
    • This is not an excuse not to support PNG export
    • Get creative! Send album art, a frame from the video, or user's game stats
    • iOS tip-- (just render a special UIView layer into an image context, then into a PNG!)
  • View the protocol outline included in ''


  • Everything in Swyp built on bonjour, sockets and streams
    • Though this is iOS code, there's no reason it can't be brought to Android and OSX
  • Swyp is peer to peer
    • Swyp supports Wifi and Bluetooth pan (in supporting devices like iOS devices) -pending @ iOS 5
    • Swyp visually presents the user with all enabled Swyp pathways (so that users know to connect to the same WiFi, for example, or turn on bluetooth)
    • Swyp could eventually be extended to support connections over cellular connections, providing a service (like Bump's) was created by some future party
  • Swyp currently is as secure as the host network
    • If the feature is widely requested, we can implement a tls certificate system as an extension
    • Insecure networks will have insecure file transfer, making Swyp about average in security
