# World Clock Pro vs Sun Clock App

The clearest difference is monetization model: Sun Clock App at free against World Clock Pro's subscription. Sun Clock App also leads on iOS requirement (9.0 vs 13.0). World Clock Pro's advantage is rating (4.8 vs 4.3) and update cadence (every 2 months vs every 33 months). On price, ads, in-app purchases and device support 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 Sun Clock App sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
