Möbius Sync's advantage is rating (3.8 vs 3.0) and ratings volume (140 vs 2). 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. EteSync Notes asks for nothing beyond the download.

Möbius Sync holds the better App Store score, 3.8 against 3.0.

Written reviews complicate that: 100% of EteSync Notes'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.
