Möbius Sync Pro is a file synchronization app that brings Syncthing to your iPhone or iPad. It enables users to sync selected files between iOS devices and other Syncthing-supported devices without relying on any cloud services. The app supports multiple folders and remote devices, offering flexibility in managing synchronized data.

Users can create synchronized folders within the Möbius Sync sandbox or by accessing other apps' sandboxes, although this feature is marked as experimental and may impact other app functionalities. Möbius Sync Pro utilizes the open-source Syncthing engine internally, ensuring secure and efficient file synchronization. This app variant offers the same functionality as the in-app purchase option in Möbius Sync (Freemium) and provides limited free features for users to explore before committing to the full version.
