Your Obsidian vault, on your own server, synced to iPhone and iPad — peer-to-peer with Syncthing, no managed note cloud in the middle. VaultSync is the iOS bridge for people who already trust Syncthing with their notes. If your vault lives on a Mac, Windows PC, Linux machine, NAS, or homeserver, VaultSync lets your iPhone and iPad join that setup — without moving anything into iCloud, Dropbox, or someone else's note-sync service. It syncs straight into Obsidian's folder on your device, so you open Obsidian and your vault is just there. WHY VAULTSYNC • Direct peer-to-peer sync between your devices and your own server. • Your Markdown never passes through our servers. We can't read, index, store, or proxy your notes — they never reach us. • No account. No sign-up. No analytics SDK. No tracking. SET UP IN MINUTES • Pair with your computer or server by scanning its Syncthing QR code (Device ID). • Pick the vaults you want on this device. • Open Obsidian — your notes are already in place. BUILT FOR REAL VAULTS • Resolve Markdown conflicts in a side-by-side comparison: keep this version, the other one, or both. • "Sync Filters" keep big folders or attachments off your iPhone and iPad. • Faster, more reliable syncing when your devices are on the same Wi-Fi. • A "Sync Activity" timeline and a "Sync Issues" panel with clear next steps instead of cryptic errors. • Home Screen and Lock Screen widgets show your last sync at a glance. • Quiet conflict notifications that update in place instead of piling up. HONEST ABOUT iOS SYNC iOS does not let third-party apps run a sync service permanently in the background, and we won't pretend otherwise: • Server to iPhone/iPad: near-realtime incoming sync when the optional Cloud Relay delivers a silent push. • iPhone/iPad to server: most reliable while VaultSync is open. Background refresh helps opportunistically, but iOS decides when it runs. • If syncing stops on its own, VaultSync tells you instead of showing "Ready". CLOUD RELAY (OPTIONAL) A small subscription (monthly or yearly) that sends a silent wake-up push the moment your server has changes, so incoming sync feels instant without opening the app. The relay only ever sees a wake-up signal — your Device ID, an APNs token, and a transaction ID. It never sees your note content, Markdown, filenames, folder names, vault structure, or any metadata. It needs a free Docker sidecar ("vaultsync-notify") on your server. VaultSync works fully without Cloud Relay — the relay only makes incoming sync faster. SUPPORT VAULTSYNC (OPTIONAL) Two one-time contributions — Small and Big — for people who want to support the project. They are a tip jar: they unlock nothing, and the app stays fully functional without them. REQUIREMENTS • iPhone or iPad with iOS/iPadOS 18 or later. • Syncthing running on a Mac, Windows PC, Linux machine, NAS, or homeserver. • Obsidian installed on your device. PRIVACY & OPEN SOURCE VaultSync is peer-to-peer by design: no managed note cloud, no telemetry, nothing to sign into. The app is open source under the MPL-2.0 license — read the code, build it yourself, or contribute. VaultSync is an independent project and is not affiliated with, endorsed by, or sponsored by Obsidian or Syncthing. "Obsidian" and "Syncthing" are trademarks of their respective owners.
