Sync lets you share your files directly from device to device without using the cloud. Sync photos, videos, presentations, PDFs, and more with unlimited sharing capacity and no folder size limits.

Sync links your devices with a private identity, which means your information is never stored on servers in the cloud. Sync skips the cloud to keep your data secure and transfers files up to 16x faster.

On-demand access to all of the synced folders on your Mac, PC, or NAS device allows you to sync your files only when you need them to save space on your Android device.

• Access your folders and files from your Android device.
• Add photos, videos, docs, and PDFs from your Android device to any of your synced folders.
• Automatically backup your photos to a folder on your computer to protect your memories.
• Files are encrypted in-flight to keep them private and protected.
• Your information is never stored on a server in the cloud.
• Take a picture of a QR code to easily connect to folders on other devices.
• Sync large folders on-demand.

2.0 Updates:
• Ability to cancel pending file transfers
• Back up your linked devices in two taps
• Change which devices you back up to at any time
• Peer list of connected devices visible for each folder
• View details for each folder including size, number of files, last synced date, and other helpful info
• Updated user interface and performance improvements
• Clear synced files to free up space on your device
• Improved action menu in the main folder list

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.

Please note that BitTorrent Sync is a personal file syncing application. It is not compatible with torrent file sharing applications.

    In the past, syncing files between different platforms was a hit or miss. Now with sync, not only it's easier, but it's way more efficient, effective, and even a joy

    2.0 and limiting to 10 folders for the free account is the reason I made the switch to open source based syncthing.

    Sometimes if I use sync on Windows and don't have it installed with admin privileges, it gets stuck in a loop of updating files and ends up erasing them. But lucky the hidden archive folder keeps everything. Thanks guys

    Neat and powerful, simply does what it claims. Not sure why there are so many bad reviews.

    I used to sync my personal stuffs with btsync, but after my laptop reinstall I realized I'm forced to use 2.0 from now on. If I don't, I cannot sync stuffs between android and PC for free, and the 10 folder restriction is ridiculous. Not to mention that the yearly 40$ for my own storage space is a bad joke. Thank God we have syncthing which does nearly the same thing without any fee and it is open
