ReceptionRating · Positive reviews · Number of ratings

World Clock Pro holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: World Clock Pro has 1.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 77% of World Clock Pro's written reviews are positive against 100% of Binary Clock by jhale.dev's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

World Clock Pro ships an update every 2 months, Binary Clock by jhale.dev every 4 months. The most recent releases landed on October 11, 2026 and September 21, 2026 respectively.
