Synctrain is the household name in syncthing, but it's far from the only option. We track 248+ alternatives and competitors on iOS — many free, many higher-rated than you'd expect.
Securely synchronize files and folders between your devices. Stream audio and video directly from other devices. Manage file sharing permissions to control access to your data.
Monitor and manage your Syncthing instances remotely. View folder and device status, system information, and logs. Connect securely using API keys and manage multiple instances from your mobile device.
Sync files between your iOS devices and other Syncthing-compatible platforms without relying on cloud services. Access files within the app's sandbox or, with a paid upgrade, integrate with other apps' sandboxes and export photos.
