V-Sync — Backup at Light Speed

Why V-Sync

The fastest, simplest way to move everything

Built for people with huge photo libraries, no iCloud space left, and zero patience for slow uploads.

Blazing fast

Real-time speed and time-remaining. Thousands of files in seconds, straight over a cable or your local Wi-Fi.

Dead-simple

No account. No sign-up. Open the app and back up instantly — anyone can use it.

No cloud, ever

Data goes straight to your drive. 100% private, no cloud subscription, no photos on someone else's server.

Every method

USB cable, USB-C drive, Wi-Fi QR between two phones, or AirDrop — there's always a way that works.

Photos, contacts & folders

Back up all your photos and videos, contacts, or any folder you choose — everything or hand-picked.

Verified & safe

Every transfer is checked so nothing is lost — then free up space on your phone with one tap.

Works with everything

No brand lock-in. Ever.

Unlike apps tied to one brand of drive, V-Sync works with whatever you already own.

Real speed, shown live

See exactly how fast — no guessing.

V-Sync shows live throughput and time-remaining as it works, so you always know what's happening. On a modern USB-C iPhone with a portable SSD, that's up to ~1 GB/s of your own data, moving on your terms.

Real speed depends on your phone, cable and drive — V-Sync gets out of the way and runs as fast as your hardware allows.

Questions, answered

Does V-Sync use the cloud?+

No. V-Sync has no servers and never uploads your data. Everything moves directly from your phone to your chosen USB-C drive or device, over a cable or your local Wi-Fi. Your photos never leave your control.

Which iPhone gives the fastest speed?+

iPhone 15 Pro and newer have a USB 3 port and can reach ~1 GB/s with a portable SSD and a USB 3 cable. Older iPhones and the standard iPhone 15/15 Plus use a USB 2 port, which caps transfers around 40 MB/s regardless of the drive.

Does it work with Android and Windows too?+

Yes. V-Sync is cross-platform — iPhone, Android, Mac and Windows. You can back up to any USB-C drive, or send files between two phones with a QR code.

Do I need a special drive?+

Any USB-C drive works — no brand lock-in. For the fastest speeds, use a portable SSD rather than a cheap USB stick, since the drive's own controller is often the bottleneck.

Is it really private?+

Yes. V-Sync collects none of your data and has no account system. Because there are no servers, there is nothing to leak. See our Privacy Policy for details.

Can I cancel anytime?+

Absolutely. Subscriptions renew until you cancel, and you can cancel anytime in your App Store settings. Prefer no subscription? Buy the Lifetime plan once and own it forever.
