SyncUp-Client
A Syncthing Client
Free · Designed for iPad. Not verified for macOS.
SyncUp is an open-source client for the Syncthing protocol.
A peer-to-peer file synchronization protocol that has been around since 2014.
If you already run a Syncthing node on your computer, NAS, or home server, SyncUp lets your iPhone join the same network of devices and keep selected folders in sync.
All transfers happen directly between devices you own, end-to-end encrypted with TLS 1.3.
This app does not host or store your files on any third-party server. It connects only to peers you have explicitly authorized.
FEATURES
• QR code device pairing -> scan a peer's code or display your own. The 56-character device ID never has to be typed by hand.
• Folder sharing controls -> accept, ignore, or auto-accept folder offers from peers you trust.
• Live status -> folder progress, peer connection state, and incoming offers update in near real time.
• Per-folder pause and resume from Settings.
HOW SYNC WORKS ON IOS
iOS reserves continuous background execution for a small set of app categories that SyncUp does not belong to. Sync runs in the foreground whenever the app is open, and SyncUp also registers two background tasks that the system schedules opportunistically, typically a short window or two per day, with the exact timing controlled by iOS.
For an always-online node, run a Syncthing instance on a computer or home server that stays powered on.
Your iPhone reconciles against it whenever it next runs.
OPEN SOURCE
SyncUp is licensed under MPL-2.0.
The Syncthing daemon is embedded in-process and the full source code is available on GitHub.
REQUIREMENTS
You will need at least one other device running Syncthing (on macOS, Windows, Linux, Android, or another iOS device with this app) for SyncUp to be useful. Visit syncthing.net

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
• Web GUI access: open Syncthing's full web interface directly from the Status screen for advanced configuration.
• New "Ignore Deletes" option in a folder's Advanced settings, so remote deletions won't remove your local files.
• Fixed the Activity/Transfers tab so active transfers and recent changes display reliably.
