• Quickeo
  
  Private File Sharing
  Quickeo is an application for people who want to share their private digital photos, videos, music and other files with their friends, family and community – not the whole world. It simplifies the transfer of private multi-media files for both the sender (no uploading to a server necessary) and the receiver (no downloading necessary).
