Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

World Time Clock Master holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: World Time Clock Master has 816 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 73% of Market Clock's written reviews are positive against 66% of World Time Clock Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Market Clock ships an update every 4 months, World Time Clock Master fortnightly. The most recent releases landed on September 9, 2026 and October 17, 2026 respectively.
