Synctrain is described as 'With Synctrain you can securely synchronize files with other devices that have Syncthing installed. You can choose to synchronize full folders, or choose specific files. With Synctrain you can also stream audio and video files from other devices' and is a File Sync tool in the backup & sync category. There are four alternatives to Synctrain for Android, F-Droid, iPhone and Android Tablet. The best Synctrain alternative is Syncthing-Fork, which is both free and Open Source. Other great apps like Synctrain are BasicSync, SyncUp (Syncthing) and Syncthing Lite.

Syncthing's official Android client was archived in December 2024. No single client ran on both phones from one codebase, so I built this. The daemon runs in-process via gomobile, with a React Native UI scaffolded from react-native-go.
