# World Clock vs World Time Clock Master

The clearest difference is rating: World Time Clock Master at 4.6 against World Clock's 3.9. World Time Clock Master also leads on ads (none vs shown) and ratings volume (816 vs 14). World Clock's advantage is monetization model (ad-supported vs subscription) and review sentiment (77% vs 66%). On price, in-app purchases and device support there is nothing between them.

Both are free to download. World Clock sells 1 one-off in-app purchase 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 3.9. That said, the two scores are not equally well evidenced: World Time Clock Master has 816 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 77% of World 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.

World Clock ships an update every 6 weeks, World Time Clock Master fortnightly. The most recent releases landed on June 9, 2026 and September 25, 2026 respectively.
