Flawless Syncthing integration

I’ve been using this app for several months and it has flawlessly been able to keep files in sync across my iPhone and multiple computers. I especially like that I can sync files from other apps.

Thank you for the kind words 🙏

Not good

UI barely works. IP entry silently fails. Accidentally deleted paired device in one click. Endless connection problems with no feedback.

Fantastic App

This is a great app to actually be able to use Syncthing with iOS. The only issue is that I cannot create a folder to sync photos. The UI resets to the folder option after a couple of seconds.

Hands down the best app doe Syncthing

Intuitive UI and fast. I’ve been using this for a couple of months and the connection to Syncthing on my Linux desktop is flawless. I use it to sync Obsidian and it’s a live saver. Thanks to the dev for adding this to the App Store.

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.
