# World Timezone Calendar vs Timezone Assistant

The clearest difference is rating: World Timezone Calendar at 4.9 against Timezone Assistant's 1.0. World Timezone Calendar also leads on ratings volume (309 vs 1) and device support (4 vs 2). Timezone Assistant's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price there is nothing between them.

Both are free to download. World Timezone Calendar sells 1 one-off in-app purchase. Timezone Assistant asks for nothing beyond the download.

World Timezone Calendar holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: World Timezone Calendar has 309 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 76% of World Timezone Calendar's written reviews are positive against 100% of Timezone Assistant's, so the app with the better star average is not the one people write more warmly about.
