# Plejd vs Duux

The clearest difference is rating: Duux at 4.7 against Plejd's 3.4. Duux also leads on update cadence (monthly vs every 2 months) and ratings volume (15 vs 5). Plejd's advantage is monetization model (free vs ad-supported). On price, review sentiment, ads and in-app purchases 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 3.4. Both are backed by a comparable volume of ratings — 5 and 15 respectively. Written reviews complicate that: 33% of Plejd'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.

Plejd ships an update every 2 months, Duux monthly. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
