# Util Monster vs The Date Calculator PRO

The clearest difference is rating: The Date Calculator PRO at 4.7 against Util Monster's 2.8. The Date Calculator PRO also leads on update cadence (every 4 months vs every 98 months) and ratings volume (2.6K vs 4). Util Monster's advantage is in-app purchases (none vs 7) and review sentiment (100% vs 66%). On price, ads and device support there is nothing between them.

Both are free to download. The Date Calculator PRO sells 7 in-app purchases, starting at $1.99 per 7 days. Util Monster asks for nothing beyond the download.

The Date Calculator PRO holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: The Date Calculator PRO has 2.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Util Monster's written reviews are positive against 66% of The Date Calculator PRO's, so the app with the better star average is not the one people write more warmly about.

Util Monster ships an update every 98 months, The Date Calculator PRO every 4 months. Both last shipped on November 6, 2026.
