ReceptionRating · Positive reviews · Number of ratings

뤼튼 holds the better App Store score, 3.8 against 2.3. That said, the two scores are not equally well evidenced: 뤼튼 has 48 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 98% of GOODDUCK's written reviews are positive against 44% of 뤼튼's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GOODDUCK ships an update monthly, 뤼튼 every 2 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
