Rsync Server
APK
This app makes the shared storage of the device available via the Rsync protocol. Shared storage is what you can see in the "File Manager" app that usually comes with the device. This includes the 'DCIM' camera image folder as well as 'Downloads'. When the "start" button is pressed and the device has Wifi connectivity, the app will open a rsync server on a random port with a random tag ("module" in rsync parlance). It will display all necessary details on how to connect to that server while it is running, e.g. rsync://192.168.123.123:66671/abcdef/ Using a standard rsync client the server can then be interrogated and files moved back and forth, i.e. to and from the phone. The benefit is that the transfers can be driven from the client desktop, the keyboard and mouse interface of which making the process much more convenient. Note: This app has not been widely tested and should therefore be considered alpha quality.

SyncUp
APK
An open-source Syncthing client for iPhone and Android, powered by the Syncthing daemon via gomobile. Syncthing's official Android client was archived in December 2024. No single client ran on both phones from one codebase, so this one was built. The daemon runs in-process via gomobile, with a React Native UI scaffolded from react-native-go. Differences from other clients: Daemon runs in-process on Android. The Go daemon lives inside the app via gomobile. There is no subprocess to manage, no IPC between a background service and the UI, and no service-restart handling. Auto-accept folders from trusted peers. When you add a peer, you can toggle auto-accept so any folder they share is added to your device automatically without a prompt. Other pending offers show up as accept/ignore cards in the Folders tab. QR pairing works both ways. Display your device's QR for a peer to scan, or scan theirs. The 56-character device ID never needs to be typed by hand. UI updates in near real time. Long-polling /rest/events means config changes, folder state, and incoming offers reach the UI in about a second, instead of on a polling interval.

APK

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.

Syncthing-Lite
APK
⚡ Revival of the app which was abandoned years ago. ✅ Safety warning: Please always ensure that you have backed up your data by other means and that this backup is up to date before using this app. The app is still in early development. ⚠️ We assume no liability for data corruption or loss, although we make every effort to deliver quality. This is an Android app which you can use as a client to access Syncthing shares offered by remote devices. It works similar to file sharing apps accessing their server. This is a client-oriented implementation, designed to work online by downloading and uploading files from an active device on the network instead of synchronizing a local copy of the entire folder. Due to that, you will see a sync progress of 0% at other devices which is expected. This is useful for devices where you don't want to download the entire contents of a shared folder. For example, mobile devices with limited storage available where you like to access a syncthing shared folder. This is quite different from the way the Syncthing-Fork app works. Please note that for technical reasons you can't reconnect via relay connection for some minutes after the app was closed. This may happen due to removing from the recent apps list, force close or an interrupted connection to remote device. This constraint does not apply for connections directly established through the local network. Source code: https://github.com/researchxxl/syncthing-lite
