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: Todotxt+ at 4.2 against Möbius Sync's 3.8. Todotxt+ also leads on update cadence (every 11 days vs every 2 months) and iOS requirement (11.0 vs 14.1). Möbius Sync's advantage is review sentiment (55% vs 36%). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Todotxt+ sells 1 one-off in-app purchase and Möbius Sync sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Todotxt+ holds the better App Store score, 4.2 against 3.8. Both are backed by a comparable volume of ratings — 60 and 140 respectively. Written reviews complicate that: 36% of Todotxt+'s written reviews are positive against 55% of Möbius Sync's, so the app with the better star average is not the one people write more warmly about.
Todotxt+ ships an update every 11 days, Möbius Sync every 2 months. The most recent releases landed on August 20, 2026 and September 25, 2026 respectively.
