Verdict

The call

The clearest difference is monetization model: World Clock at free with in-app purchases against Hours Keeper's subscription. World Clock also leads on ads (none vs shown) and rating (4.4 vs 4.1). Hours Keeper's advantage is review sentiment (57% vs 32%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Hours Keeper sells 9 in-app purchases, starting at $1.99 per month and World Clock sells 3 in-app purchases, starting at $0.99 per 6 months. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

World Clock holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 1.4K and 1.3K respectively. Written reviews complicate that: 57% of Hours Keeper'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.

UpkeepUpdate frequency

Hours Keeper ships an update monthly, World Clock every 2 weeks. The most recent releases landed on October 2, 2026 and October 1, 2026 respectively.
