ReceptionRating · Positive reviews · Number of ratings

Silent library challenge holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Silent library challenge has 3.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of Buzzer's written reviews are positive against 19% of Silent library challenge's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Buzzer ships an update every 23 months, Silent library challenge every 3 weeks. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
