# Mill Norway vs Duux

The clearest difference is rating: Duux at 4.7 against Mill Norway's 4.3. Duux also leads on device support (3 vs 1). Mill Norway's advantage is ratings volume (270 vs 15) and update cadence (every 11 days vs monthly). On price, ads, in-app purchases and iOS requirement there is nothing between them.

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

Duux holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Mill Norway has 270 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 38% of Mill Norway's written reviews are positive against 29% of Duux's, so the app with the better star average is not the one people write more warmly about.

Mill Norway ships an update every 11 days, Duux monthly. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
