# On vs xCluster

The clearest difference is review sentiment: xCluster at 100% against On's 50%. On's advantage is rating (4.4 vs 4.0) and device support (4 vs 1). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 13 and 5 respectively. Written reviews complicate that: 50% of On's written reviews are positive against 100% of xCluster's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. Both last shipped on November 3, 2026.
