# World Class vs Бассейн Чайка

The clearest difference is ratings volume: World Class at 292 against Бассейн Чайка's 5. World Class also leads on update cadence (monthly vs every 4 months) and review sentiment (69% vs 50%). Бассейн Чайка's advantage is rating (5.0 vs 4.8). 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.

Бассейн Чайка holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: World Class has 292 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 69% of World Class's written reviews are positive against 50% of Бассейн Чайка's, so the app with the better star average is not the one people write more warmly about.

World Class ships an update monthly, Бассейн Чайка every 4 months. The most recent releases landed on October 14, 2026 and October 8, 2026 respectively.
