# Calculator # vs Acute Calculator

The clearest difference is ads: Acute Calculator at none against Calculator #'s shown. Acute Calculator also leads on review sentiment (95% vs 60%) and update cadence (every 2 days vs every 2 months). Calculator #'s advantage is ratings volume (36K vs 116) and iOS requirement (12.1 vs 16.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and Acute Calculator sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Acute Calculator holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 116, so its average is the more settled of the two. Written reviews point the same way: 60% of Calculator #'s written reviews are positive against 95% of Acute Calculator's.

Calculator # ships an update every 2 months, Acute Calculator every 2 days. The most recent releases landed on September 26, 2026 and July 16, 2026 respectively.
