ReceptionRating · Positive reviews · Number of ratings

Beonyeok holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Beonyeok has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Caesar Shift Plus's written reviews are positive against 75% of Beonyeok's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Caesar Shift Plus ships an update every 7 months, Beonyeok every 3 days. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
