Sync is the best way to transfer files between your Mac, PC, NAS, and even server.

Create your own private cloud. Connect devices and sync files securely without sending them on third-party servers. We don’t limit your speed or storage space: our technology works especially well with huge files.

No storage limits
• Sync as much data as you have on your hard drives.

Automatic camera backup
• Sync will back up photos and videos as soon as you take them.
• You can then delete photos from your phone and save space.

Direct transfers, no cloud
• Your information is never stored on servers in the cloud, so nobody can access it without your permission.
• Transfer files directly and fast using peer-to-peer technology (p2p).

Any device and platform
• Access folders and upload files to your tablet, PC, Mac, NAS, and even server.

Supports all file types
• Add photos, videos, music, docs, and PDFs from other apps to any of your synced folders.

Save space
• Selective Sync lets you save only the files you need.

To get the best performance and to avoid running up your data charges while syncing folders, we recommend leaving the "Use Cellular Data" setting off.

I've used Sync on all my devices since it was in beta. Fast, reliable, encrypted and easy to set up and use.

Been using it for 4 years

I’ve been using it to backup my photos from iPhone to NAS server and it’s been great. Especially nice to be able to backup to own HDD anywhere in the world and not rely on cloud services.

This app is PERFECT!

I can't believe how lucky I am! I downloaded this app a couple of days ago. Synced it with a folder on my iMac. The syncing was seamless and I was so happy to find such a fast way to sync a folder with your iPhone. Then I found out there was no share sheet available for single files which meant that I couldn't send the file via email or social media. It made the app completely useless for me. I got so unbelievably disappointed.

And lo and behold, this update comes along like a gift from God himself all of the sudden. This app has existed for over a year, and it's not until the very week I download it that the app get this amazing update. Can't be a coincidence. Anyway, I'd give the app a million stars now if I could. Many thanks to the devs! It's amazing!
