Syncthing: Fast, Private File Syncing Between Android, Windows, iOS – My Experience

For years, I struggled with clunky cloud services and complex sync tools until I discovered Syncthing—a blazing-fast, open-source file synchronization solution that works directly between devices with no central server required. After using it to sync files between my Android phone and Windows PC, I’m convinced this is the future of personal data synchronization.

What Makes Syncthing Revolutionary?

Syncthing replaces proprietary cloud services with a decentralized, peer-to-peer approach:

Zero Cloud Dependency: Your files sync directly between devices, eliminating third-party storage and privacy risks .
Military-Grade Security: All transfers use TLS encryption with perfect forward secrecy .
Complete Control: Devices authenticate via cryptographic certificates—only your explicitly approved devices can connect .

“Syncthing is everything I used to love about computers… It’s amazing how great computer products can be when they don’t need to deal with corporate bullshit.”

My Android-Windows Sync Setup

1. Windows Installation (Minutes):

Download the .exe from syncthing.net .
The intuitive interface (shown below) lets you manage folders and devices effortlessly.

2. Android Setup (Critical Tip):

Use Syncthing-Fork (Google Play Link) instead of the deprecated official app .
Key advantages:
Camera Roll Sync: Auto-syncs DCIM/Camera and Pictures/Screenshots .
Battery Optimization: “Sync every hour” mode reduces drain .
SD Card Support: Writes to external storage on Android 11+ .

3. iOS Möbius Sync (Third-Party Client)

What it does: A paid app ($5) that acts as a Syncthing client for iOS (App Store Link).
There is a trail version with 20 Mega limit.
Access files from the Files app on iOS.

3. Pairing Devices:

Scan your PC’s QR code (from Syncthing’s web UI) using the Android app .
Share specific folders (e.g., Screenshots, Documents)—no need to move files to special directories like ~/Dropbox .

Real-World Performance Highlights

Speed: Files sync in seconds over Wi-Fi. Screenshots taken on my phone appear on my PC before I switch apps .
Reliability: Despite initial worries about partial syncs (mentioned in some reviews ), I’ve had zero corrupted files.
Storage Flexibility: Sync any folder.

Advanced Tips I Learned

Exclude Junk Files: Use .stignore to block temporary files (e.g., *.tmp). Check settings page/screen.

Limitations to Consider

Initial Setup Complexity: Pairing devices via device IDs feels technical (typing long IDs is tedious—use QR!) .
Not a Backup Tool: Deleting a file on one device deletes it everywhere. Enable file versioning for safety .

Why I’ll Never Go Back to Cloud Sync

Syncthing isn’t just a tool—it’s a philosophy shift:

No corporate lock-in, no upsells, no hidden limits .
Works offline—syncs resume seamlessly when devices reconnect.
Community-driven enhancements like the Android fork’s “Camera Roll” feature keep improving usability .
