Möbius Sync Pro

A Syncthing-based file synchronization client for selected iPhone or iPad folders and compatible remote devices.

Our take

Consider for users who understand peer synchronization

Multiple folders and peers offer a way to move chosen files without requiring a conventional cloud-storage provider.

Keep in mind: Access to other apps' sandboxes is explicitly experimental and can break their functionality. Synchronization is not a versioned backup and iOS execution limits still matter.

What you can do

  • Synchronize selected folders with compatible Syncthing peers
  • Access app-sandbox folders through Files
  • Export photo-library folders send-only
  • Configure multiple remote devices

Good for

  • Users prepared to test a small folder and retain an independent backup before wider synchronization.

Consider alternatives for

  • People expecting risk-free access to arbitrary app data or unrestricted always-on iOS background behavior.

Limitations & considerations

  • Captured minimum: iOS 15.0.
  • Access to other apps' sandboxes is explicitly experimental and can break their functionality. Synchronization is not a versioned backup and iOS execution limits still matter.

Privacy & permissions

Peer devices receive synchronized content. Verify trusted peers and folder direction before adding confidential documents.
