Möbius Sync brings Syncthing to your iPhone or iPad, allowing you to synchronize selected files between iOS devices and other devices supported by Syncthing, without the need for any cloud service. Supports multiple folders and multiple remote devices. Synchronized folders can be created either: 1. in the Möbius Sync sandbox and files can be added to and retrieved from shared folders via the iOS Files app; or 2. (PAID feature) by accessing other apps' sandboxes. This feature is EXPERIMENTAL and may break other app's functionality. Uses the open-source Syncthing engine internally. Usage within the Möbius Sync sandbox is free up to 20MB. Unlimited file sync, including files in other apps' sanboxes is available for a one-time purchase. NOTE: The functionality unlocked by in-app purchase is identical to that in Möbius Sync Pro (which is purchased up-front).
