LinSyncLinSync and ChronoSync
The ChronoSync way of working, on every computer
ChronoSync, by Econ Technologies, is a well-loved sync and backup app for the Mac. LinSync was modelled on it: synchronizer tasks, a trial run before anything changes, an archive of replaced files, and schedules. The difference is where it runs, and what comes in the box.

Where LinSync goes further
- The same app, and the same backups, on Windows, Mac and Linux.
- Computer-to-computer backups are built in and free, across a Mac and a Linux PC in either direction.
- Expert's side-by-side view lets you drag files between any two computers or clouds, not just schedule tasks.
- Every copy is checked against the original by fingerprint, on by default, and made again if it doesn't match.
- Space shows what's filling a drive and turns any slice into a backup or a clear-out.
- A five-question wizard for people who just want it done.
- Free, with the code open for anyone to read.
Where ChronoSync is still ahead
- A direct connection to iCloud Drive, which LinSync can only use as a folder.
- Triggers when a drive or server is connected.
- Bootable copies of a Mac. Apple's recent changes make these hard for any app, and LinSync points Mac users to Time Machine.
- A signed and notarised app, with many years of polish and several languages.
If you only ever use Macs and need those, ChronoSync is a fine choice. If you have a mix of computers, or don't want to pay, LinSync does the everyday jobs on all of them.
ChronoSync and ChronoAgent are products of Econ Technologies, Inc. LinSync is a separate project with no connection to them. ChronoSync details and prices are taken from econtechnologies.com in October 2026 and may have changed since.
