# Time Zone Calculator vs World Clock

The clearest difference is rating: World Clock at 4.4 against Time Zone Calculator's 3.2. World Clock also leads on ratings volume (1.3K vs 6). Time Zone Calculator's advantage is in-app purchases (none vs 3) and review sentiment (50% vs 32%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. World Clock sells 3 in-app purchases, starting at $0.99 per 6 months. Time Zone Calculator asks for nothing beyond the download.

World Clock holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: World Clock has 1.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of Time Zone Calculator's written reviews are positive against 32% of World Clock's, so the app with the better star average is not the one people write more warmly about.

Time Zone Calculator ships an update monthly, World Clock every 2 weeks. The most recent releases landed on June 11, 2026 and September 23, 2026 respectively.
