Mobile Sync

One-way vault sync from PC to Android over local WiFi — no cloud, no account, no cables.

How it works

• PC runs a local HTTP server exposing your vault's files
• Android fetches a file manifest, diffs it against local state, and downloads only what changed
• PC is the single source of truth — mobile vault is kept in sync automatically

Both devices must be on the same WiFi network. Obsidian must be open on your PC.

Installation

From community plugins

Search for Mobile Sync in Obsidian's community plugin browser.

Manual

1. Download main.js and manifest.json from the latest release
2. Create folder .obsidian/plugins/mobile-sync/ in your vault
3. Copy both files into that folder
4. Enable the plugin in Obsidian settings

Setup

PC

1. Enable the plugin — the server starts automatically on port 27123
2. Check the status bar for your local address, e.g. Sync server: running on 192.168.1.105:27123

Android

1. Install the plugin in your Android vault the same way
2. Go to Settings → Mobile Sync
3. Enter the PC address: http://192.168.1.105:27123
4. Tap Test connection to verify
5. Use the ribbon sync button or wait for auto-sync on startup

• .obsidian/ is always excluded from sync
• Files present on Android but not on PC are deleted — mobile is read-only
• Sync processes files in batches of 20 to respect Android memory limits
• Only markdown files are synced
