Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 65.21 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

This is a fork of the Syncthing-Android wrapper for Syncthing that brings major enhancements like:
* Folder, device and overall sync progress can easily be read off the UI.
* "Sync every hour" to save even more battery
* Individual sync conditions can be applied per device and per folder
* Recent changes UI, click to open files.
* Changes to folder and device config can be made regardless if Syncthing is running or not
* UI explains why syncthing is running or not.
* "Battery eater" problem is fixed.
* Discover other Syncthing devices on the same network and easily add them.
* Supports two-way synchronization on external SD card since Android 11.

Syncthing-Fork for Android is a wrapper for Syncthing that provides an Android UI instead of Syncthing's built-in Web UI. Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Syncthing-Fork safe to install?
