# SphereKnight vs YUSEONG

The clearest difference is rating: YUSEONG at 5.0 against SphereKnight's 4.8. YUSEONG also leads on update cadence (every 2 months vs every 4 months). SphereKnight's advantage is ratings volume (6 vs 1) and iOS requirement (8.0 vs 13.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. SphereKnight sells 1 one-off in-app purchase and YUSEONG sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

YUSEONG holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: SphereKnight has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

SphereKnight ships an update every 4 months, YUSEONG every 2 months. The most recent releases landed on September 26, 2026 and October 7, 2026 respectively.
