# U.F.Moo! vs SphereKnight

The clearest difference is rating: SphereKnight at 4.8 against U.F.Moo!'s 3.0. SphereKnight also leads on ratings volume (6 vs 2) and iOS requirement (8.0 vs 15.0). U.F.Moo!'s advantage is in-app purchases (none vs 1) and review sentiment (100% vs 69%). On price, update cadence, ads and device support there is nothing between them.

SphereKnight holds the better App Store score, 4.8 against 3.0. Both are backed by a comparable volume of ratings — 2 and 6 respectively. Written reviews complicate that: 100% of U.F.Moo!'s written reviews are positive against 69% of SphereKnight's, so the app with the better star average is not the one people write more warmly about.
