# Calculator +ㅤ vs Acute Calculator

The clearest difference is review sentiment: Acute Calculator at 95% against Calculator +ㅤ's 46%. Acute Calculator also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). Calculator +ㅤ's advantage is ratings volume (4.5K vs 116). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days 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 +ㅤ has 4.5K ratings behind it against 116, so its average is the more settled of the two. Written reviews point the same way: 46% of Calculator +ㅤ's written reviews are positive against 95% of Acute Calculator's.

Calculator +ㅤ ships an update fortnightly, Acute Calculator every 2 days. The most recent releases landed on September 23, 2026 and July 16, 2026 respectively.
