Useful but buggy

Random UI and syncing bugs occur, thanks to vibe coding.

切后台就会断连是咋回事?这bug修不了没必要做同步吧

Thank you!!

Superb app, the only solution that made Syncthing work for me on iOS.

App is legit

Great solution for cross-platform file sync

I need to sync a lot of commonly used files across multiple systems, and have used cloud storage for this purpose over many years. But after giving up on Dropbox and then struggling with maintaining my own Nextcloud instance, none of that is even necessary; Synctrain allows for synchronising directories across multiple systems without any need for external network access or monthly storage costs, and because it uses Syncthing behind the scenes, it’s fully cross-platform. Install a Syncthing client in Android, Linux, or others, and it all works seamlessly with Synctrain. 👍

My one complaint is that file ignore lists must be set up per-computer and per-sync-folder. Tedious and unintuitive. But that’s a very long-standing issue with Synchthing, _not_ Synctrain.

Many thanks to the developer, this is a great solution and so much easier than managing Synchthing in Linux, so at least _one_ ecosystem is super easy to set up with syncing (MacOS/iPadOS/iOS). 😅

FAQ

What does Synctrain do?

Synctrain allows you to securely synchronize files and folders between devices that have Syncthing installed. You can choose to sync entire folders or select specific files. It also enables you to stream audio and video files directly from your other devices.

How does file synchronization work?

When you synchronize files using Synctrain, any changes made, including deletions, are mirrored across all your connected devices. This ensures your files are consistent everywhere. However, it is crucial to remember that this app is not for backup purposes, and you should maintain separate backups of your data.

Is Synctrain free to use?

Yes, Synctrain is a free application. It does not have ads or in-app purchases, making it a completely free solution for your file synchronization needs.

What devices is Synctrain compatible with?

Synctrain is designed to work with other devices that have Syncthing installed. The specific compatibility will depend on the operating systems and versions of Syncthing supported on those devices.

Can Synctrain be used for backing up my files?

No, Synctrain explicitly states that it should not be used for backup purposes. While it synchronizes files across devices, it does not function as a backup solution. Always maintain a separate, independent backup of your important data.
