# Tmzn vs World Time Clock Master

The clearest difference is rating: World Time Clock Master at 4.6 against Tmzn's 3.8. World Time Clock Master also leads on ratings volume (839 vs 4). Tmzn's advantage is in-app purchases (none vs 13) and update cadence (every 3 days vs fortnightly). On price, ads and device support there is nothing between them.

Both are free to download. World Time Clock Master sells 10 in-app purchases, starting at $2.99 per month. Tmzn asks for nothing beyond the download.

World Time Clock Master holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: World Time Clock Master has 839 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of Tmzn's written reviews are positive against 67% of World Time Clock Master's, so the app with the better star average is not the one people write more warmly about.

Tmzn ships an update every 3 days, World Time Clock Master fortnightly. The most recent releases landed on October 25, 2026 and October 27, 2026 respectively.
