# Kstert vs XiuXiu

The clearest difference is rating: XiuXiu at 4.0 against Kstert's 2.9. Kstert's advantage is review sentiment (37% vs 0%) and ratings volume (36 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

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

XiuXiu holds the better App Store score, 4.0 against 2.9. That said, the two scores are not equally well evidenced: Kstert has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 37% of Kstert's written reviews are positive against 0% of XiuXiu's, so the app with the better star average is not the one people write more warmly about.

Kstert ships an update every 3 weeks, XiuXiu every 2 months. The most recent releases landed on September 21, 2026 and July 6, 2026 respectively.
