# Market Clock vs World Time Clock Master

The clearest difference is rating: World Time Clock Master at 4.6 against Market Clock's 3.7. World Time Clock Master also leads on update cadence (fortnightly vs every 4 months) and ratings volume (816 vs 7). Market Clock's advantage is monetization model (free with in-app purchases vs subscription). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Market Clock sells 2 in-app purchases, starting at $0.99 per month and World Time Clock Master sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

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.

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.
