# World Clock Pro vs iSafeCharge+

The clearest difference is monetization model: iSafeCharge+ at free with in-app purchases against World Clock Pro's subscription. World Clock Pro's advantage is rating (4.8 vs 4.3) and review sentiment (77% vs 53%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. World Clock Pro sells 5 in-app purchases, starting at $1.99 per month and iSafeCharge+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

World Clock Pro holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: World Clock Pro has 1.3K ratings behind it against 77, so its average is the more settled of the two. Written reviews point the same way: 77% of World Clock Pro's written reviews are positive against 53% of iSafeCharge+'s.

World Clock Pro ships an update every 2 months, iSafeCharge+ monthly. The most recent releases landed on October 11, 2026 and October 5, 2026 respectively.
