# ownCloud vs Möbius Sync

The clearest difference is rating: ownCloud at 4.5 against Möbius Sync's 3.8. Möbius Sync's advantage is review sentiment (55% vs 32%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. ownCloud sells 6 in-app purchases, starting at $1.99 per year and Möbius Sync sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ownCloud holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 352 and 140 respectively. Written reviews complicate that: 32% of ownCloud'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.

ownCloud ships an update every 3 months, Möbius Sync every 2 months. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
