Chessbook - Master openings

Chessbook - Master openings has retreated noticeably from its all-time peak of #18, hit on 2026-08-22, with a last-30-day average of around #53. It is currently visible only in the App Store Top Grossing Education chart, and only in four smaller markets: Cayman Islands (#43, down 3), Greece (#43, down 23), Romania (#66), and Finland (#70, down 19). The downward movement across every tracked country, combined with the gap between the recent peak and the current #43–#70 range, indicates a clear falling trajectory. The app is no longer approaching its earlier high-water mark and is steadily slipping down the monetization charts.
