Store screenshots supplied by the developer.
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:
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; or
3. (PAID featured) iOS Photo Library folders can be exported to other devices send-only.
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.…

mobius-syncWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
