Keep a safe copy of everything that matters. Sync is the multi-cloud backup app that backs up, restores, and syncs your files across your iPhone/iPad, USB and external drives, and 5 major cloud services — so whatever happens, you have a copy and a way to get it back. 5 sync modes | 5 cloud services | 4 platforms PROTECT WHAT MATTERS Set up a backup task once — choose what to protect and where it goes — then run it whenever you want. You decide what's backed up, and nothing moves your files in the background. EVERY CLOUD YOU USE Back up and sync your OneDrive, Google Drive, Dropbox, and more — connect as many as you need, all in one app instead of juggling five separate apps: • OneDrive • Google Drive • Dropbox • Box • Amazon S3 BACK UP BEYOND THE CLOUD Back up and sync straight to USB and external drives too, so you're covered even without an internet connection. Or keep files right on your device: Private Drive is secure in-app storage just for Sync, and Public Drive shares files with your other apps through Finder/Files. GET ANY FILE BACK Browse every file across every connected drive from one place, and pull back anything you need — no separate file manager required. CONTROL HOW YOUR FILES FLOW Five modes give you exact control over your file backup and cloud sync — not one-size-fits-all: • Full Sync • Backup • Restore • Backup Sync • Restore Sync The three sync modes — Full Sync, Backup Sync, and Restore Sync — only transfer changed files, so repeat runs stay fast. SHARE FILES OVER WI-FI Turn your device into a local web server: anyone on the same Wi-Fi can browse and download the files and folders you choose, straight from their browser. No cloud upload, no cables. READY ON EVERY DEVICE Also available for Android, macOS, and Windows — so you can back up from whatever device you're on. FREE TO START Connect one drive and try Sync at no cost (ad-supported, with usage limits). GO PREMIUM One upgrade unlocks every cloud service, USB and external drive support, and removes ads — as a subscription or a one-time lifetime purchase. Whatever happens — a new device, a bigger drive, or a file you need back — your files are ready. Download Sync and keep a copy of everything that matters.
