# World Time Clock Master vs ExplainIn

The clearest difference is monetization model: ExplainIn at free against World Time Clock Master's subscription. ExplainIn also leads on review sentiment (100% vs 66%) and update cadence (daily vs fortnightly). World Time Clock Master's advantage is ratings volume (839 vs 1) and iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases 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 and ExplainIn sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ExplainIn holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: World Time Clock Master has 839 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 66% of World Time Clock Master's written reviews are positive against 100% of ExplainIn's.

World Time Clock Master ships an update fortnightly, ExplainIn daily. The most recent releases landed on October 21, 2026 and October 22, 2026 respectively.
