# World Clock vs Time Zone Clock

The clearest difference is ads: Time Zone Clock at none against World Clock's shown. Time Zone Clock also leads on rating (4.4 vs 3.9) and update cadence (every 11 days vs every 6 weeks). World Clock's advantage is review sentiment (77% vs 59%) and monetization model (ad-supported vs free with in-app purchases). 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 Time Zone Clock sells 8 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Time Zone Clock holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Time Zone Clock has 253 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 59% of Time Zone Clock'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, Time Zone Clock every 11 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
