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. by accessing other apps' sandboxes. This feature is EXPERIMENTAL and may break other app's functionality. Uses the open-source Syncthing engine internally. NOTE: The functionality in this Möbius Sync Pro app variant is identical to that which can unlocked by in-app purchase is in Möbius Sync (Freemium) - that has limited functaionality available for free for users who wish to try before purchase.

With Synctrain you can securely synchronize files with other devices that have Syncthing installed. You can choose to synchronize full folders, or choose specific files. With Synctrain you can also stream audio and video files from other devices. When you synchronize files, all changes, including deleting files, also happen on your other devices. Do not use Synctrain for back-up purposes, and always keep a back-up of your data. You decide with which devices you share which files. This also means the app makers cannot help you access or recover any lost files. This app is powered by Syncthing. This app is however not associated with or endorsed by Syncthing nor its developers. Please do not expect support from the Syncthing developers. Instead, contact the maker of this app if you have questions.
