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.
