bnClock holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: bnClock has 35 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 56% of bnClock's written reviews are positive against 100% of Perch Door Sim's, so the app with the better star average is not the one people write more warmly about.
bnClock ships an update every 2 months, Perch Door Sim every 4 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
