Verdict
The clearest difference is in-app purchases: Calculator%. at none against Calculator #'s 6. Calculator #'s advantage is ratings volume (36K vs 4.2K). On price, rating, review sentiment and update cadence 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. Calculator%. asks for nothing beyond the download.
Calculator # holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 4.2K, so its average is the more settled of the two. Written reviews complicate that: 60% of Calculator #'s written reviews are positive against 61% of Calculator%.'s, so the app with the better star average is not the one people write more warmly about.
Calculator # ships an update every 2 months, Calculator%. every 3 months. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
