ChronoAgent is an application that runs in the background on a remote Mac and communicates directly with ChronoSync or InterConneX on another device. It provides a direct, high performance, encrypted connection and is the ultimate way to transfer files.

ChronoMonitor is an iPhone app that checks the availability and condition of ChronoAgents installed on a network. It also receives push notifications from ChronoSync, letting you know that your scheduled syncs and backups are running properly.

InterConneX is a file storage, file management, and file sharing app for your iPhone or iPad. Manage files and folders on your device or share them directly with other iDevices or Macs. File management that is safe and secure — no cloud service required!
