VaultSync for Obsidian
Self-Hosted Vault Sync
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Sync your Obsidian vaults to iPhone and iPad with Syncthing. Your notes stay on your devices — no note cloud, no account, no tracking.
VaultSync brings self-hosted Obsidian vault sync to iPhone and iPad — powered by Syncthing.
If you already run Syncthing on your Mac, Linux machine, NAS, or homeserver, VaultSync turns your iOS device into a peer in your sync setup. Your Markdown files sync directly into Obsidian’s iOS sandbox, so you can open Obsidian and start writing.
No note cloud. No account. No tracking.
HOW IT WORKS
1. Install VaultSync on your iPhone or iPad
2. Connect your existing Syncthing device via QR code
3. Accept the connection on your desktop/server
4. Select your Obsidian vault
5. Open Obsidian — your notes are there
WHY VAULTSYNC?
• Built for Obsidian
VaultSync syncs directly into Obsidian’s iOS folder, so your vault is available where Obsidian expects it.
• Powered by Syncthing
Use the sync protocol you already trust on desktop, server, NAS, and homelab setups.
• Self-hosted by default
Your notes sync between your own devices. VaultSync does not require an account, analytics SDK, or managed note cloud.
• Optional Cloud Relay
For faster server-to-iPhone updates, Cloud Relay can wake your iPhone when your server has changes. The relay only handles wake-up signals — never note content, filenames, folder names, or vault metadata.
• Conflict resolver
When edits conflict, VaultSync helps you compare Markdown changes and choose the right version.
• Clear diagnostics
See sync status, activity, and common setup issues directly inside the app.
IMPORTANT IOS BACKGROUND NOTE
iOS does not allow third-party apps to run an always-on sync daemon. Server-to-iPhone updates can be near-realtime with optional Cloud Relay. Changes made on iPhone sync most reliably when you open VaultSync.
REQUIREMENTS
• iPhone or iPad with iOS/iPadOS 18 or later
• Syncthing running on a desktop, server, NAS, or homelab device
• Obsidian installed on iOS
VaultSync is free and open source under MPL-2.0.
VaultSync is not affiliated with Obsidian or Syncthing.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
In this update, we’ve made getting started with VaultSync even easier and tidied up the settings. Here is what's new for you:
A Quicker Start: Getting started is now a breeze with a short, two-screen introduction. The actual setup has been moved right to your home screen—exactly where you already manage your devices, vaults, and syncing.
Clearer Status Overview: The old setup guide in your Settings is now a handy live status view. You can instantly see what's working perfectly, what still needs your attention, and exactly how to fix it.
Actionable Shared Vaults: If someone shares a vault with you, it's now much clearer when you still need to accept it. Syncing will only show as "ready" once you have at least one fully active vault.
Tidier Settings: We’ve removed some of the technical clutter to keep your settings menu clean and simple. Device discovery now just works smoothly in the background by default.
New Languages: The updated setup and status screens are now fully translated and available in English, German, and Simplified Chinese.
iOS 18 Support: VaultSync is now fully optimized for iOS 18 and iPadOS 18 (and newer).
