# Crowns vs Duono

The clearest difference is price: Crowns at Free against Duono's $2.99. Crowns also leads on rating (4.5 vs 4.0) and ratings volume (491 vs 1). Duono's advantage is in-app purchases (none vs 1) and review sentiment (83% vs 69%). On ads, device support and iOS requirement there is nothing between them.

Crowns is free to download; Duono costs $2.99 up front. Crowns sells 1 one-off in-app purchase. Duono asks for nothing beyond the download.

Crowns holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Crowns has 491 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 69% of Crowns's written reviews are positive against 83% of Duono's, so the app with the better star average is not the one people write more warmly about.

Crowns ships an update every 4 weeks, Duono every 2 weeks. The most recent releases landed on October 22, 2026 and October 11, 2026 respectively.
