# World Cal vs MilliLife

The clearest difference is ads: MilliLife at none against World Cal's shown. MilliLife also leads on review sentiment (100% vs 76%). World Cal's advantage is rating (4.9 vs 4.4) and ratings volume (318 vs 7). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. World Cal sells 1 one-off in-app purchase and MilliLife sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

World Cal holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: World Cal has 318 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 76% of World Cal's written reviews are positive against 100% of MilliLife's, so the app with the better star average is not the one people write more warmly about.

World Cal ships an update every 4 months, MilliLife every 3 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
