# World Clock Pro vs GMT Time

The clearest difference is in-app purchases: GMT Time at none against World Clock Pro's 6. World Clock Pro's advantage is ads (none vs shown) and ratings volume (1.3K vs 37). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. World Clock Pro sells 5 in-app purchases, starting at $1.99 per month. GMT Time asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for World Clock Pro against 4.7 for GMT Time. That said, the two scores are not equally well evidenced: World Clock Pro has 1.3K ratings behind it against 37, so its average is the more settled of the two.
