# GPS Speedometer vs World Time Clock Master

The clearest difference is rating: World Time Clock Master at 4.6 against GPS Speedometer's 4.0. World Time Clock Master also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). GPS Speedometer's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (4.2K vs 839). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. GPS Speedometer sells 11 in-app purchases, starting at $1.99 per 7 days 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 4.0. That said, the two scores are not equally well evidenced: GPS Speedometer has 4.2K ratings behind it against 839, so its average is the more settled of the two. Written reviews split almost evenly too, at 66% and 67% positive.

GPS Speedometer ships an update every 2 months, World Time Clock Master fortnightly. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
