Verdict
The clearest difference is rating: Calculator # at 4.6 against Util Monster's 2.8. Calculator # also leads on update cadence (every 2 months vs every 193 months) and ratings volume (36K vs 4). Util Monster's advantage is review sentiment (100% vs 60%) and in-app purchases (none vs 6). On price, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month. Util Monster asks for nothing beyond the download.
Calculator # holds the better App Store score, 4.6 against 2.8. That said, the two scores are not equally well evidenced: Calculator # has 36K 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 60% of Calculator #'s, so the app with the better star average is not the one people write more warmly about.
Util Monster ships an update every 193 months, Calculator # every 2 months. The most recent releases landed on October 11, 2026 and October 19, 2026 respectively.
