ReceptionRating · Positive reviews · Number of ratings

Bigger Butt in 30 Days holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Bigger Butt in 30 Days has 993 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 86% of UpDown's written reviews are positive against 78% of Bigger Butt in 30 Days's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UpDown ships an update every 4 weeks, Bigger Butt in 30 Days every 2 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
