What Syncthing-Fork adds on Android
Syncthing-Fork provides a native Android interface around Syncthing and adds controls intended to make synchronization easier on phones and tablets. The project highlights readable folder/device sync progress, per-folder and per-device sync conditions, scheduled syncing and a Recent Changes interface.
It also supports two-way synchronization to external SD cards on modern Android versions and can discover other Syncthing devices on the same local network.
What changed in 2.1.5.0
The current F-Droid changelog lists a modernization of the Recent Changes screen and a fix for the embedded Web GUI not loading correctly.
Why decentralized sync is different from cloud storage
Syncthing synchronizes data directly between devices you control. There is no requirement to upload the master copy of every file to a central storage provider. Users choose which folders are shared, which devices receive them and how synchronization is routed.
This makes Syncthing-Fork useful for people who want phone-to-PC, phone-to-NAS or multi-device file synchronization while retaining control over where data is stored.
Permissions and background operation
File synchronization requires broad storage and network access, and Syncthing-Fork can run background services so transfers continue when appropriate. F-Droid also lists location/Wi-Fi-related permissions that support local network discovery and Android networking behavior.
Users should review battery-optimization settings if synchronization pauses unexpectedly in the background.
Reproducible-build status
F-Droid’s verification service shows a successful reproducibility result for version 2.1.5.0 / code 2010500. That means the verification system was able to rebuild the application and match the published APK for that release.
Direct APK vs F-Droid client
The direct APK button above is appropriate for manual installation. F-Droid recommends using its client when possible because repository installation provides update notifications and repository metadata automatically.

Bottom line
Syncthing-Fork is a high-quality direct-download topic for SSM Apps: it is open source, actively maintained in 2026, has a reproducible F-Droid build and solves a practical Android-to-PC/NAS synchronization problem without requiring a proprietary cloud provider.
