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).

Verdict
The clearest difference is rating: Möbius Sync at 3.8 against QR Shot's 3.0. Möbius Sync also leads on ratings volume (140 vs 2) and update cadence (every 2 months vs every 7 months). QR Shot's advantage is in-app purchases (none vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Möbius Sync sells 1 one-off in-app purchase. QR Shot asks for nothing beyond the download.
Möbius Sync holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: Möbius Sync has 140 ratings behind it against 2, so its average is the more settled of the two.
QR Shot ships an update every 7 months, Möbius Sync every 2 months. Both last shipped on October 21, 2026.
